Who doesn't love lilacs? The ideal lilac shrub has about 10 canes and produces flowers at eye-level—all the better to enjoy that sweet, haunting fragrance.

Lilacs do come in seven colors but most are familiar with the common lilac, Syringa vulgaris, which blooms in the northern states for 2 weeks in late May. However, there are early-, mid-, and late-season lilacs, which, when grown together, ensure a steady bloom for at least 6 weeks.

Lilacs are hardy, easy to grow, and low maintenance. They can grow from 5 to 15 feet tall, depending on the variety. The fragrant flowers are good for cutting and attractive to butterflies.

Planting

  • Grow lilacs in fertile, humus-rich, well-drained, neutral to alkaline soil (at a pH near 7.0). If your soil is in poor condition, add compost to enrich.
  • Select a site where your lilac will get full sun—at least 6 hours. If lilacs don't get enough sun, they will not bloom well.
  • Make sure the site drains well. Lilacs don't like wet feet and will not bloom with too much water.
  • Plant in either spring or fall, although the latter is preferred.
  • If you're lucky, a friend will give you a sucker, or offshoot, of the root system of one of his plants. Your sucker will look pathetic at first but just dig a hole, backfill it with soil, and stick the sucker in. Then water and wait. In 4 or 5 years, you'll be rewarded with huge, fragrant blossoms.
  • Transplanting lilacs from a nursery is also easy. If it's container-grown, spread out the roots as you settle the plant into the ground; if it's balled or burlapped, gentle remove it and any rope before planting. Set the plant 2 or 3 inches deeper than it grew in the nursery, and work topsoil in around the roots. Water in. Then fill in the hole with more topsoil.
  • Space multiple lilac shrubs 5 to 15 feet apart, depending on the variety.

Care

  • Each spring, apply a layer of compost under the plant, followed by mulch to retain moisture and control weeds.
  • Water during the summer if rainfall is less than 1 inch per week.
  • Lilacs won't bloom if they're overfertilized. They can handle a handful of 10-10-10 in late winter, but no more.
  • After your lilac bush has finished blooming, spread some lime and well-rotted manure around the base. Trim the bush to shape it, and remove suckers at the same time.

Pruning Lilacs

  • Lilacs bloom on old wood, so it's critical to prune in the spring right after they bloom. If you prune later in the summer, you may be removing the wood. Here's a tip: If your lilac flower clusters are getting smaller, time to prune!
  • Every year after bloom, remove any dead wood. Prune out the oldest canes (down to the ground). Remove the small suckers. Cut back weak branches to a strong shoot. Cut back tall canes to eye height.
  • If your lilac is old and in really bad shape, remove one-third of the oldest canes (down to the ground) in year one, half of the remaining old wood in year two, and the rest of the old wood in year three. Another option for old lilacs is to chop the whole thing back to about 6 or 8 inches high. It sounds drastic, but lilacs are very hardy. The downside to this option is that it takes a few years to grow back. The upside is less work and more reward, as the lilac will grow back bursting with blooms. 
  • It must be recognized that severe pruning results in the loss of blooms for one to three years. For these reasons, a wise pruning program aims to avoid severe and drastic cuts by giving the bushes annual attention. 

Pests

  • Prone to attack by slugs and snails.
  • Powder white mildew may appear after a summer of hot, humid weather. It may be unsightly, but it does no harm. Ignore it.

Recommended Varieties

The most common and fragrant lilacs are of the S. vulgaris variety:

  • For early bloom, try 'Charles Joly', a double magneta.
  • Mid-season lilacs include 'Monge', a dark reddish purple, and 'Firmament', a fine blue.
  • Late-season beauties include 'Miss Canada', a reddishpink, and 'Donald Wyman', a single purple.

Although common lilacs love cold weather, a few thrive as south as Zone 9, among them the cutleaf lilac, a fragrant pale lavender. Syringa patula 'Miss Kim' is a graceful shrub with pale lilac-blue flowers that fade to white.

Special Features

  • Attracts Butterflies

Wit & Wisdom

  • To improve the flowering of lilacs, keep the grass from growing around them. A 16- to 24-inch circle of landscape cloth placed around the bushes and covered with bark or stone will keep the grass down.
  • Force a winter bouquet from cut branches of lilac. Bruise the cut ends and set them in water. Spray the branches frequently. Keep them in a cool place until they bloom, then move to a warmer area for display.
  • Poet Walt Whitman thought of lilacs when Abraham Lincoln died: 
    "When lilacs last in the dooryard bloom'd . . . I mourn'd, and yet shall mourn with ever-returning spring."

We moved into a house 2 years

By butterflymama5 on November 10

We moved into a house 2 years ago with 2 lilac bushes on the side of the house. They are only about 2 - 2 1/2 ft off the house. They are tall (about 6+ ft) and the backs that are against the house are just sticks, no leaves. The first year they did bloom but this year they only got about a total of 5 flowers between the two of them. I'm not sure whether to dig them up or just cut them low. What would you recommend with them being so close to the house? Thanks!

If you want to keep your

By CindyMR on November 13

If you want to keep your lilac bushes, wait till after they bloom in Spring and then trim. NEVER trim lilac after June. It will take off next years flowers that start setting in July. (Cut to the ground,) any branches with no leaves on them, cut any that are touching the houses, and trim bush to look nice. Sprinkle bonemeal around the bushes to help with next years flowers.

I'm no expert, but I love lilacs and to search and find information about lilacs for me is fun. There are many sites that you can go check out like this one on the net. Do some searches and you will find tons of fellow lilac growers. Good luck and happy growing!

I am ready to plant out two small lilac shrubs and would like to put them in a garden bed on each side of our inground pool waterfall, this spot is in full sun all day.
I read from your responses to others that there should be at least 20 meters from domestic drains...would this apply to our concrete inground pool too?
Thank you.

My wife had a lilac bush

By Jeff Mayer

My wife had a lilac bush about 3' tall planted on a slope at the corner of our paved driveway, There is a long log berm on one side to hold back the slope from the driveway and unfortunately in heavy rains (which we get a lot of) water
pours down through this corner area. She thought the plant would help prevent erosion of the soil in that spot. It doesn't, and mulch and soil got washed away so easily that I had to put a layer of garden stones over the area to help hold it. Needless to say the lilac is not thriving, leaves are brown and curling and falling off. Is there something I can do to help it survive in this location or would it be best to try to move it to a better drained are?

Hi Jeff, You will be better

By Almanac Staff

Hi Jeff,
You will be better off moving the lilac to a different location. Depending on where you live you should do it as soon as possible, before the cold weather arrives. Look att our planting advice on this page for best results.

I purchased through the mail

By Byron's LuLu

I purchased through the mail a Lilac about 20 years ago. I planted it and it bloomed. Then for about 17 years it didn't. It remained no taller than about 2'. About 2 years ago it grew a side branch (still short)full of leaves and it had 2 blooms!!..also 2 more shoots from the main plant. I lost my husband and was forced to move from my home..I just felt the need to take the lilac with me. I figured I would lose roots, but it was small, so I gave it a try. That was Los Angeles, CA. I potted it around end of May..or 1st of June this yr. And yes, had to cut a large root. The leaves have begun to curl under, but the ends are FULL of leaf buds that seem to be sleeping but firm. I am now by the sea..Central Coast, CA. Do we have a chance?

Hi Lulu, Well...lilacs are

By Greenwood Nursery

Hi Lulu,
Well...lilacs are typically cooler weather plants. Even here in TN (zone 7) is about as far south as the old fashioned lilac will grow.
Heat and humidity are not welcomed by lilacs and would be the reason for not blooming or growing to it's potential in your location.
After digging and potting your plant, it was certainly stressed, but, it does sound as though the plant is sleeping. Try to keep it in the 'coolest' area of your yard where it is not in direct path of the warm winds coming off the water. A shaded and protected area would be good. Keep watch so that the soil doesn't dry out and it should leaf out in spring. Best!

Hi, I took a sapling from my grandmother's house in northwestern PA and have it in a pot at my house in southern Indiana just outside of Louisville KY. I am worried that it might freeze this winter if I plant it now. Would it survive indoors? How much sun would it need in the winter?

By Almanac Staff

It would be best if you can plant the lilac outdoors as soon as possible. Water well and add mulch around the plant. See our planting advice above. Lilacs need at least 6 hours of direct sunlight.

I have a very old lilac hedge

By PegCityGinny

I have a very old lilac hedge that runs along my fence. I just moved into this house and need to drastically cut it back. I don't think it has been pruned in 5-10 years and it is completely overgrown. I have had to trim the section that runs along the road even though it is fall here because the branches were stretching on to the street and disrupting the view of drivers. I would also like to cut about 1-2 feet off the top of the hedge but am wondering if I should wait until spring to do this? I live in Manitoba. Also, will cutting the top increase the number of leaves that grow further down? The hedge acts as privacy but because it has gotten so tall there aren't as many leaves lower down.

Wait till Spring after the lilacs flower and then prune. If you prune now, you will cut the flowers that are set for next Spring.

By BOB P.

I live in northern NJ on the top of a mountain/hill and have 2 big, purple lilac bushes.
I have a few seedlings that have com up about 2ft. high or so and want to transplant them to another are close by. The soil here seems dry. Do I need to add lime or mircale grow?

Also, the seeds have been coming out brown for a couple of yrs or more. Is there something wrong with them?

Hi Bob, If your soil is dry

By Almanac Staff

Hi Bob,
If your soil is dry or sandy add compost before planting the seedlings. See our planting and care advice above. Lilacs usually produce clusters of brown seed pods after flowering.

Thanks for the quick

By BOB P.

Thanks for the quick response. I forgot to check this.
Compost meaning peat moss or something like that?
How many seedlings should I plant together to have success n do you how long with they take to get about 5/6 ft. high?

Compost is usually made by

By Almanac Staff

Compost is usually made by gathering plant material, such as leaves, grass clippings, and vegetable peels, into a pile or bin and letting it decompose. You can find bags of compost at your local garden center. Don't plant the seedlings too close. Give them some room to develop roots. It will take a few years for the lilacs to grow 5 feet high.

Pale leaves? Last year, I

By Jenny m

Pale leaves? Last year, I planted a row of lilacs I dug up from my mom's bushes. I have very sandy alkaline soil here, just northwest of the Twin Cities by about an hour. I added two new ones this year, and noticed that the older ones, while they otherwise look healthy, have very pale yellow leaves, not the nice dark green of the new ones. I mulch them with compost and a bit of bone meal in fall and spring and they had suckers this spring. They are about 4 feet from the road (and snow plow) and two feet from a natural gas line. Could this be harming them, maybe a leak? Or is it a nutrient deficiency? I am afraid to add lime to an already alkaline soil.

Yellow leaves can be caused

By Almanac Staff

Yellow leaves can be caused by too much or too little water. If your road is salted in the winter that can contribute to the problems.
Spread a few inches of dry aged manure around the lilacs in early spring and midsummer next year. The aged manure helps replenish nutrients to the soil and the manure also helps in moisture retention.

I live in Sac CA and have a 8 yr established dwarf korean lilac. I noticed this year there are less leaves and blooms. Recently I noticed portions of my bush are dying and the leaves are drying from the ends inward. What can I do to try and save this once beautiful bush?

Your problems can be weather

By Almanac Staff

Your problems can be weather related. Hot dry summers or harsh winters can cause a lilac to not put out as many leaves as usual. Have you checked the soil? Potassium and/or magnesium deficiency can cause a lilac not to grow well. Diseases and bugs can also cause leaves and branches to die. Remove and discard the dying branches and inspect for insects. Water well.

By Almanac Staff

Hi, Eugene: Although somewhat difficult, it is indeed possible to grow lilacs from cuttings, but the cuttings need to be relatively fresh -- which yours don't seem to be. That being said, you've got nothing to lose, so dip the cutting ends in water and then in rooting hormone (ask your garden center), and then put them in some (continually) moist peat pots deep enough so that they don't fall over. Keep them well misted and lit for at least a month. Eventually, give them a little tug to see if you get resistance -- then you'll know. In the meantime, nurture what remains in the ground by making sure that it does not dry out. Good luck!

I recently planted a young

By Juliett Jones

I recently planted a young Dwarf lilac, its been a week and a half or so since I planted it. Roots were in a huge ball in the planter, but I didnt see any rope or burlap that needed removing. We have had good rainfall amounts so I don't think it's thirsty, but its leaves are drying up and brittle. I'm told it may still be suffering transplant shock but I'm worried that maybe I should have un-balled the roots or planted it deeper then I did. I listened to my mother when she said to just take it out of the planter and plop it in the ground as I have never planted anything before. SHould I dig it back up and check the roots, then plant it deeper or leave it be and place some compost or plant sticks around it? I don't know what to do but it's my 1st plant so Im a bit attached to it and worried that I killed it somehow.

By Almanac Staff

You didn't mention where you live. Generally the best time to plant a lilac is in the fall or spring. Leave the lilac in the ground for now and try to shade it if you have hot weather. Make sure that the soil is moist.

By Almanac Staff

It sounds like stress from being dried out. Lilacs need deep and infrequent watering not shallow, frequent watering. You can water about 9 to 12 inches deep in one go, then wait until the ground is dry down to 6 inches deep, then repeat. We would also mist the leaves of a newly planted lilac.
Do not prune it! That's more stress. Do not overwater. Do not fertilize. If the plant is still green beneath the bark, there is a chance for recovery. Continue with normal care and see if it recovers. If it's too far gone, you'll need a new plant. Good luck!

30 years ago, my wife and I saw lilacs 25-35 feet tall with 6-8 inch dia trunks. They were limbless to about 10 feet above the concrete and had a 12 to 16 foot dia drip line.

Assuming they were grafted what would be a good choice for root/trunk stock?

There are several types of bracket fungi. These fungi usually attack old and weak trees and bushes after a tree has been damaged by man or nature. Some suggest to remove branches with the fungi to prevent further spread and also to improve the soil and growing conditions. The fungi likes moisture so make sure the soil drains well and that the lilacs don't stand in wet soil. There is not much else you can do.

Hello! Last year we planted three tall lilacs in our backyard and are having issues with droopy leaves. We thought we killed them last year, but they have come back. They are planted in an area with full sun, are spaced appropriately and we are careful not to over water or over fertilize. Unfortunately we can't seem to get them looking healthy.

By Almanac Staff

Pine trees are tough. They suck up moisture, cast lots of shade, and are generally not especially hospitable. Lilacs are not the best choice as they require lots of sun and moisture. If you wish to plant near the pine, the best options are plants that tolerate some shade, acidic soil, and low moisture. Examples: hydrangea, azalea, rhododendron, and bleeding heart.

By Almanac Staff

Hi, Helen, This is not something we have direct experience with (yet), so we'll tell you what we would do. Wait a while. Hopefully, the mower blade was set high and there is something left of the plant, some shred of a stem. It might have enough root to come back from this. If/when it makes an adequate recovery (as seen by new growth), then gently clear the grass from around it and mulch it. In the meantime, make sure that it is clearly marked on your property. You don't want someone stepping on it. Or mowing it again. Good luck!

I bought a very healthy looking 4-feet tall Little Kim Lilac in a pot, it was full of blooms.

I was busy so it was left inside the garage for 3 days, after I took it outside and watered it, the next day the leafs were all curled up and blooms look wilted and lost their fragrance.

By Almanac Staff

This is a generally low-maintenance variety; however, it likes full sun and medium water. If the garage takes direct sun and it was closed, it may have become oppressively hot in there and weakened the plant. A full soak or two, allowed to drain off, in moderate sun could help but it could take a couple or a few days. In the meantime, consult the folks that you bought it from or a local nursery.

I have a lilac bush that has been therefor 5 years. I fertilized my lawn ( next to the bush) and sprayed a weed killer on same lawn this year. The lilac was very happy and blooming and now some blooms are dead in their tracks and the leaves are wilting in some spots, but not the whole bush. Please help! Have I killed it?

We can't tell if you killed

By Almanac Staff

We can't tell if you killed it, Amanda, but the chemicals could certainly be affecting it. Read the labels on the ferilizer and weed killer packaging. (If you discarded it after using, revisit your source and read it there.) Some provide warnings about use near other plants, and many provide phone numbers for specific questions such as this. Call and ask about the ingredients (especially the weed killer's components) and what effect they might have. They might advise watering to dilute; you won't know what to do until you know what it is.

I live in Buffalo New York and have a lilac bush that is many years old.. for years the flowers have been all over the bush and plentiful but now the just grow at the top (for the past 2 years or so ) . Please help I love lliacs but would love to see more flowers ???

Hi Lisa, This is a common

By Almanac Staff

Hi Lisa, This is a common question. Many old lilacs only flower at the top--and you really do want those gorgeous fragrant lilacs at eye-level.
The best practice is to cut back the entire plant within 6 to 8 inches of the ground before they leaf out (usually March or early April). You won't get flowers the first season but this severe pruning induces shoots to develop during the growing season. The following year, select the strongest, healthiest shoots and cut back to just above the bud to encourage branching. Remove all other shoots at ground level.
Or, for a more reserved approach, try a three-year program: Chop off one-third of all the older canes back as close to the ground as possible. The plant will send up a flush of leafy growth that should bud this summer and look better next year. Repeat the process every year until you have pruned all the older canes. Don't prune too late (after July) or you remove the flower buds for the next growing season.

I recently bought 3 lilac

By KSouthern

I recently bought 3 lilac bushes, I planted them last weekend. I have been watering them regularly, some of the leaves are turning dark green and curlying under. Am I over watering or is something else happening? I am just starting to try and plant things. My soil is very sandy, I put composte and top soil into the holes that I dug. Thank you for any information!!

Curling leaves are often a

By Almanac Staff

Curling leaves are often a sign of dryness. Try digging into the soil to see if the moisture is getting to the roots. Your noting that your soil is sandy is a clue, even if you did the right things by adding compost and soil. The question is, is there enough of these ingredients for the plant to have a chance to absorb the water? Although lilacs don't like to sit in water, water passes quickly through sand—maybe too quickly for your plant to get any. Water more often, even laying the hose running lightly to moderately (not gushing and pushing soil around) and see if there is improvement. You might have to remove it, enlarge the hole, add more compost and soil, even peat moss (which holds water), and replant.

Not sure how to plant too ( no green thumb here). I know you said spring and fall is the best time to plant. I live in Central PA..

Miss Angie, We would never

By Almanac Staff

Miss Angie, We would never argue with directions on a plant tag. Soak the roots in a bucket or under a running hose or the like until saturated. This will help them adjust to being underground, however, you still meed to water the plant in its new spot.
See "Planting" above for more advice on planting. (Note that we say above that lilacs do not like "wet feet," but yours says right on it to soak it. If you have further questions about that, you might consult the source from which you got the plant.)
Enjoy it!

I live in MA and have 5 old

By echogirl3142

I live in MA and have 5 old fashioned purple lilacs lining my property line. I bought and planted then 5 years ago, and even the first year-when the nursery deemed them dead, once we got them home and planted they shot up, out and bloomed profusely. They've done beautifully each year up until now. This year we have TONS of blooms on each plant, but 4/5 have almost no leaves. There don't appear to be any signs of distress,mold, borers etc..and we've had an "average" spring with normal rain, and temps, but we did have a bitingly cold winter. Any ideas one why the plants would be in full bloom but with minimal leaves?!

Thanks in advance!

The severe winter can have

By Almanac Staff

The severe winter can have caused some of the leaf problems. We recommend that you add bonemeal and compost to the soil around the lilacs and also add some mulch on top to keep the soil nice and moist. After the blooms have faded prune out any dead branches and cut some of the longer branches.

By Ruth Joress

Four years ago I got lilac cuttings for a gift and planted them in my yard in full sun. The purple bush is now about 6 feet tall and very lush but only has a few blooms at the top ( 2nd year of blooms). The white plant is smaller and has more blooms. The flowers are gorgeous! How do I get my large bush to flower more? The bush looks like it's thriving but hardly any flowers! Thanks for any advice,

Lilacs need time to mature

By Almanac Staff

Lilacs need time to mature before they begin flowering. Your plants are still young. The blooms for the first few years will be sparse but should increase with time. Most varieties start blooming after three or four years.

By Almanac Staff

Lilacs do not like to be planted too deep but 7 inches is a bit shallow; recommended depth is about 12 inches. If the tire is only a ring around the tree and and not a true container, the plant's roots should grow into the ground. Your bigger question is will it survive a hungry moose.

I live in upstate SC near the mountains. I planted a lilac in my new neighborhood yard last spring. It had a little bloom. We had a ton of rain. It dropped all leaves and looked dead for the rest of the year but came back this spring. This year, we had a late freeze but a few weeks ago, it bloomed and looked very healthy. Now the blooms and leaves are dead again....Its only May but we had hot weather. I have been watering. It gets about 6 hours of sun no evening sun. Why do the leaves keep dying off? We have red clayish soil.

Lilacs drop leaves if they get too much water or too little water. You clay soil is not the best choice for lilacs. Try amending the soil around the lilac with compost and sand. Then add some mulch to the top of the soil.

Hi, I have a lilac bush that's about 5 yrs old planted on the west side of my apt that has never bloomed. It's right next to the brick of my apt. I'm wondering if it may be too hot in the summer and not getting enough sunlight? It's still only about 2 feet tall. Should I transplant it into a large container? Our apts won't let us plant out in the yard and I'm in a four-plex type apt so I've got western and southern exposure in my part of the yard and we have a large live oak in the yard next door to me so my front yard gets shade for most of the morning and then the late afternoon sunlight.

Hi Joan,
Growing lilacs in Texas can be tricky. Not knowing what variety of lilac you have you can try to plant it in a container and see what happens. You need a lilac variety that is heat tolerant and accepts mild winters. The cut-leaf lilac with small clusters of fragrant flowers will do well. Here are a few other lilacs that also do well in the south: 'Lavender Lady', 'Blue Boy, 'Sylvan Beauty'  and 'Miss Kim'.

My son lives in Northeast Utah and has lilac bush growing on his side of a chain link fence, but his neighbor has the same bush which flowers more abundantly. Soon after the bush flowers, it seems to die back and leaves turn yellow and die off. I have read all the comments here, but don't seem to see a situation that would apply to him. His bush does get abundant sun exposure. Watering is not an issue as they have sprinklers in their yard. Any other suggestions?

Overwatering can sometimes cause yellowing leaves; check if the soil offers enough drainage. Also, check for signs of insect pests or diseases, which can hamper the energy of the plant.

By Almanac Staff

According to your own Cornell University (and other sources), common lilac (Syringa vulgaris), as the name implies, is the best known of all the lilacs in the United States. This shrub can be as tall as 20 feet, and the flowers are fragrant and usually lilac-colored, although they can be of other hues. Leaves are somewhat heart shaped and smooth.
If you want something more unusual and are convenient to Rochester, head to Highland Park Gardens for the lilac festival there on May 9 through 18.

By Kgabby

I live in northeast Ohio and am trying to grow a lilac bush in a large pot, since I don't have a yard/garden for the time being. I bought my lilac last summer and it bloomed. In late fall I brought the plant indoors and it bloomed again, then turned brown and dry. I am not sure if it was hibernating or dying, but watered it periodically throughout the winter. I have had it back out on the balcony now for 2-3 weeks where it gets plenty of sun, but no signs of green leaves. Any advice for how I can help it come back, or when to leave it for dead? Is there any benefit to trimming back all the branches now while it still looks dead?

Lilacs need a cold winter in order to grow and produce flowers. Although you meant well, your protecting it from last winter's cold contributed to its failure to thrive. Cut it back a bit at a time and see if you see any green(-edged), or fresh, wood. That would be a sign of life. If you do not, it is probably gone.

I had a wonderful dark purple

By garden love

I had a wonderful dark purple lilac tree growing near our old house. I took a cutting and dipped the end of the cutting in a rooting hormone, it rooted and now it's outside my present house. If you do this take a nice smaller branch thats not booming, cut with sharp tool at a 45* cut then follow the instructions on the rooting hormone package. It's not the whole tree but it's a nice way to take the tree without possibly losing the whole thing. I've also taken part of the bush using a sharp shovel, but that was another variety (bush). The dark purple was a tree.
wishing you luck.

It may be difficult to

By Almanac Staff

It may be difficult to transplant an old lilac. The root system is big and you want to get as much of it as possible. It can also be stressful to the plant. However, it can be done with care. Be aware that it may also take 1 to 3 years for it to recover and bloom. The timing must also be right: when they are dormant in early spring before the plant leafs out or in the fall. If you decide not to move the bush you can transplant suckers (offshoots from the bush). Use a sharp shovel to cut the underground stem that joins the offshoot to the lilac bush. and then carefully lift the sucker, trying to retain as many roots as possible.

For a lilac wall or hedge,

By Almanac Staff

For a lilac wall or hedge, just make sure you leave plenty of room between plants (6 feet for most varieties).  Chinese lilacs make a nice hedge. If you mix the lilac with trees, just avoid any trees that will grow tall and produce shade because lilacs need sun to flower. Perhaps a conifer shrub would work. Visit your garden center for local varieties. As the lilac trunks can look bare after the flowing season, we would consider planting hostas and perennials at ground level.

If your lilac will get around

By Almanac Staff

If your lilac will get around 6 or more hours of direct sunlight, then it should be fine. Lilacs can grow in partial shade, but they will not bloom as profusely and may look more scraggly.
 
Choose a dwarf or shorter variety, such as 'Bloomerang', Korean dwarf lilac, 'Miss Kim', or 'Little Boy Blue', so that it won't overgrow the space; (still, some dwarfs can grow to 5 to 8 feet, so you'll need to keep up with pruning). Prune and water as needed. Provide good air circulation and good drainage. You may need to repot as the plant grows; allow a good amount of space for the roots to grow. Avoid black plastic pots, as these may get too hot.
 
Chicago is USDA Plant Hardiness Zone 6, so make sure that your cultivar is hardy in that Zone. Still, it might be good to provide winter protection (wrap the base and bush with burlap filled with leaves or straw; remove in early spring before new growth starts, but after last expected spring frost).
 
Good luck!

By Almanac Staff

In terms of pruning: this is done right after flowering. Otherwise, you are removing this year's blooms.
If your lilac looks more like a tree than a bush and is overgrown, you could do a severe pruning. Each year for 3 years, remove a third of the volume by cutting the large branches to the base of the plant.
In terms of transplanting, lilacs are quite hearty and if they are not too old, they will transplant well as long as they are not coming into leaf. It's ideal to transplant lilacs (and divide them if you wish) in early spring while it's still dormant. For many areas, that might be April 1 but it depends on your location.

By Almanac Staff

Hi Tommie,
A hard pruning is not going to kill a healthy lilac. Your lilac may be weak from the borer damage and may die. If you have some new growth this spring you can take a few soft wood cuttings before all the leaves open. Make the cuttings 6 to 8 inches long and make sure each cutting has two or three nodes. Remove the leaves from the lower half of the cutting and dip the bottom into rooting hormone before planting in a pot with well-draining staring mix. Mist the leaves and keep the soil moist. The cutting should root in about 6-7 weeks.

Hi, Donna, This is an unusual

By Almanac Staff

Hi, Donna, This is an unusual question. Our only thought is that this is a pruning issue. When lilacs don't fully bloom this is often due to late or early season pruning. If you prune, do so immediately after flowering, as the flower buds on lilacs develop on subsequent new growth. Pruning in August, for example, would remove those newly formed flower buds; pruning in March would also remove them just prior to flowering.

Why, lilacs bloom when

By Almanac Staff

Why, lilacs bloom when grasshopper eggs hatch! I don't suppose this is the answer you're seeking.
They are one of the first flowering bushes/shrubs to bloom just after the forcythia (another cue!)

Lilacs generally bloom in late May for 2 weeks and, as you said, their blooms don't last long. However, there are late-blooming varieties which bloom in early June.
June 14 seems a bit late, however, it is highly dependent on weather and hard to predict. It's possible that the lilacs will still be blooming if we have have a late, snowy spring.

Lilacs transplant very well and spring is the best time to do it. Make sure to get as much of the rootball as you can.

Hi, I live in central California, and I have a lilac tree that is over 10 years old. Every spring, it has bloomed beautifully; however, this last spring, we had some really cold winds, and neither the leaves nor the flowers opened all of the way. Since then, I have had no new foliage, and what I did have has turned brown. I do not believe that water is a problem, and when I cut off a small cutting, the wood is clearly green and still alive. I would appreciate any advice that comes my way. Thanks! Kim

By SherylR

I have a lilac tree (unknown variety)I planted a 6-7 years ago. It grew tall very quickly and flowered wonderfully but last year it got very spindly so after it flowered I cut it back. This year I have new leaf growth on the trunks but they are small and colored differently than the regular leaves. And my regular leaves are growing with splits on their sides and are curling strangely. Any ideas on splitting leaves or tall spindly bushes? I have planted a couple small volunteers under the tree hoping to have them grow to fill in the empty spaces in the tree. I live in Colorado and I have to admit this year we have had the strangest weather, very hot and humid with cold/cool spells from one day to the next.
Also, I used to live in Alabama and there were several french lilacs growing in the area, they were the most fragrant lilacs I've ever smelled. Will that type of lilac thrive here on the front range? I would love to plant them here.

I have moved back north Saulte Ste Marie, MI. There were 2 large bushes on the west side of the house, so big they had been tied up with rope and not taken care of for several years. I cleaned them up and cut them back, not to the ground however. They are leafed out and looking full, they are old, old lilacs. Should I cut them back more, trim them, leave them alone?? What can I do about the many shoots growing around each bush, are they taking away from the main plant. There are too many for me to dig up. Help and Thanks.

Just continue to remove any

By Almanac Staff

Just continue to remove any dead wood and prune out the oldest canes each year. If this doesn't work, you could try more serious pruning as discussed on this page. In terms of suckers, here is more detail:  If your lilac grew on its own roots, it is not "required" to remove the suckers but know that they wll grow into new branches which will flower in a few years. It depends on what you envision for your property. It's only the grafted lilac that requires removal of suckers. If you leave the suckers from below the grafting, the suckers will overtake the graft.

Young lilacs generally take

By Almanac Staff

Young lilacs generally take time to bloom. Most flower after 3 or 4 years though some take longer. Some tips: Prune at the right time as lilacs bud off old wood and you may be removing the flowers. Prune 2 or 3 weeks after the time when they would have flowered. It's good that you have sun. Give them slightly alkaline soil (pH 6-7) as too much acid can affect blooming.  Don't give lilacs too much nitrogen fertilizer which encourages lush leaves at the expense of blooms. Hope this helps!

I have mature lilacs that bloomed beautifully last year. I cut back extensively late fall/early winter. This spring the foliage was abundant but just a few blooms. We've had a dry year here in western Oregon could it be from lack of water? I did not give any additional watering I left it to nature. I live on a horse farm with lots of good horse compost. Should I amend soil annually? I have not done that in the past. Thanks!

Hi, Alex, Every year we

By Almanac Staff

Hi, Alex, Every year we receive letters from people who are disappointed that their lilacs bloomed sparely. Sometimes older lilacs need a big prune, but if you prune lilacs back extensively, it may also take a number of years before they bloom again. They should produce flowers in time, but it could take one to three years, sometimes longer. See pruning section above.
Fertilizer is rarely the answer to a plant that isn't blooming. Lilacs are not heavy feeders; if your soil is fertile, that is usually fine. Amending with manure or organic matter is helpful; the only "rule" with lilacs is to avoid fertilizer with excess nitrogen which causes leaf growth at the expense of bloom.
Moisture isn't usually related to lack of blooms; it's associated with plants' roots and how well they thrive. Lilacs do best in well-drained soil.
You did not do anything wrong. It's OK to prune extensively. For older plants that need complete renovation, we often prune with a foot of the ground. However, it must be recognized that severe pruning results in the loss of blooms the following year(s).

Hi Lori, We do get lots of questions from southern readers who would like to grow lilacs (just as northerns would like to grow tropical flowers!). Lilacs simply don't thrive in warm climates. It's not just the Sun; lilacs need a long period of winter chill in order to bloom well. A good substitute for lilacs in the South is lilac chaste tree (Vitex agnus-castus).  If you find a lilac that blooms well in your region, we'd love to know! There are always new experiments.

Hi Sarah, There are many

By Almanac Staff

Hi Sarah, There are many reasons why the lilac may not have established well. For example:
Did you plant in the spring before the buds starting to unfold?
Did you plant too deep? You wan to set lilacs 2 or 3 inches deeper than it grew in the nursery.
Did you get a soil test? (Lilacs aren't picky but they don't like acidic soil).
Is the soil fertile? Did you add in compost?
Does the soil drain well? Lilacs hate "wet feet" and you don't want the roots to rot. 
Did you water it in -- and keep the soil moist (not wet) for the first 3 to 4 weeks? 
Do you have mulch around the lilac--if so remove! 
Lilacs do naturally send out roots to survive.
You may wish to get a sample to your cooperative extension because there are many reasons why the lilac may not be doing well. Normally, they transplant well (assuming it was healthy when you planted it!).

By Almanac Staff

Summer is not a good time to plant a lilac. It may be in transplant shock which is why it is wilting. The best you can do to save it is to keep it well-watered and closely monitor its soil moisture. Make sure the root ball and surrounding soil isn't dried out. Water deeply, then let the surface dry between the next (deep) watering. Also, while compost in the hole is a good idea, we would not advise putting fertilizer in the hole itself; this can cause root burn. You may want to bring back your receipt to the nursury if you have a guarantee.

Need some advice! Hope I did

By TheWizardTim

Need some advice! Hope I did not just kill our Lilac bushes.

I believe they are Miss Kim / Manchurian Lilac based on pictures I've seen. I had previously gotten advice and seen tips online on how to prune when they get too big. Ours were about 8' tall, had finished blooming a few weeks ago, and have started to sprout a lot of extra shoots and leggy branches in recent years, despite trying to cut those away at the base. Basically only the top 15" or so of the plants were producing leaves (but did bloom very well the last couple years).

I was told I could do a "10 year pruning" where I leave the biggest, healthiest trunks intact but cut them back by 1/2 to 2/3 (not all the way to the ground - more like 2-3 feet with the taller cuts in the middle of the plant), with the idea that the cut-back trunks will produce new spouts this summer, that can then start thickening / growing next spring and summer and hopefully blooms the following year.

Now I'm reading people recommend you do it in winter, and 6-8 INCHES off the ground! Which is it? Did I just kill our lilacs because I cut them in summer? Also I didn't disinfect the shears... we don't have any diseased plants on our property so didn't think it necessary. Should I tar-cap the exposed trunks on the tops?

Main reason I cut them back is they were covering our windows and to the point I needed a ladder to prune the tops of the bushes (which still seem to add another 6" every year despite pruning / thinning. Was trying to "reshape / reset" the plant so the good stems that would contribute to a more rounded form (not sticking out at odd angles), would regenerate leafy growth and eventually flowers in a couple years.

What should I do now... put a hose at the base of the plant for 5-10 minutes each week maybe?

Miss Kim's do have a tendency

By Almanac Staff

Miss Kim's do have a tendency to outgrow their space. For lilacs, the most important rule is timing. Prune soon after flowering -- not in late summer nor winter nor early spring -- or you remove their buds and blooms. Also remove all dead limbs. You can also rejuvenate older lilacs by completely cutting all stems down to 4 to 6 inch stubs, generally in February and March. However, some readers have found that the Miss Kims do not respond well to this method (unlike the old-fashioned lilacs). Miss Kims seem to prefer regular pruning--starting early in their life--before they get out of control.

About 4 years ago, my husband

By LilacLane

About 4 years ago, my husband gave me a lilac bush for my birthday. It was purchased from a local horticultural services business. We planted it in the late spring - following the directions which came with the bush. However, while the leaves are green and it has grown a little bit (maybe half again as tall as it was when we bought it), it has never bloomed. There have never even been any buds. I'm wondering if there is anything that can be done to encourage my little bush to bloom?

We're guessing that the most

By Almanac Staff

We're guessing that the most likely cause in your case for no blossoms would be that the bush is still too young to flower. Some lilacs may take up to 5 or 7 years to start blooming.

Although you have followed the directions which came with the bush, it might be good to double-check that the plant is still getting at least 6 hours of sunlight (has other growing vegetation started to shade your bush?), and that the soil is slightly acidic to slightly alkaline (pH 6.0 to 7.5). A fertilizer high in nitrogen promotes leaf growth over blossoms; if you need to fertilize, choose one whose N-P-K ratios are about even, and only apply a small amount; lilacs don't do as well in rich soil. Also, make sure that the plant is getting enough water (about an inch per week).

You can propagate lilacs by either digging up suckers or taking cuttings from the bush. Your best bet is finding a sucker (ideally 2 to 3 foot tall). With a spade dig down around the sucker. You'll find a connecting root leading back to the main stem. Cut this root off just outside of the sucker's root ball. Remove the sucker with the roots and plant it in a big pot with potting soil. Water well.

By Almanac Staff

It is possible to grow a new lilac from a very young cutting, but it is very challenging and it usually fails. You need to use a cutting that from new growth that is between 4 and 6 inches in length, no more. Dip the fresh-cut end in water and then rooting hormones; then plant in a hole with moist potting soil If it takes, roots will form in 6 to 8 weeks. Grafting is much more successful than propagation by cuttings.

By Amy From

We have 4 very large bushes of lilacs at our new house in Manitoba that we just moved into and I just noticed blooms(June 20) but they are very sparse and small. There seems to be a lot of brown hardened blooms (are these old blooms from this year or pevious years) and there is quite a few empty holes with just branches, no leaves. What is the best way for me to get these big and healthy again?

Barring any diseases, such as

By Almanac Staff

Barring any diseases, such as blight, your lilacs may just need rejuvenative pruning. When lilacs get older, they may stop leafing out along the lower branches, and they flower less vigorously, and usually only at the top of the bush. Many lilacs bloom best on wood that is about 3 to 5 years old.

To rejuvenate an old lilac, to renew its form and encourage flowering, you can prune all stems in late winter, when the plant is dormant, down to about 6 or 8 inches high. This will encourage new shoots to develop during the growing season. The next late winter, select a few large, healthy stems and prune out the rest. For the stems that remain, cut back to a bud to encourage branching. With this drastic method, you may not get flowers until two or three years later.

Another way to rejuvenate an old lilac, and one that is easier on the plant but takes longer, is that first late winter, remove about a third of the old stems (to ground level). The next late winter, remove about half of the remaining old stems, and a little of the new growth. Keep some strong stems of the new growth. The third late winter, remove the remaining old growth, and thin out the new growth. With this method, you might have a few flowers the first two years, and then the plant should start flowering fully the third year.

In both methods, once the plant is re-established, prune out a bit of the old growth every 3 to 5 years, in spring after flowers have faded, to keep it productive. (Lilacs bloom on old wood, so are usually pruned for maintenance just after flowering in spring, so that the next year's flowers aren't removed.)

You'll see similar comments

By Almanac Staff

You'll see similar comments on these pages from fellow lilac lovers. Common reasons for lack of bloom: 1. Pruning at the wrong time since lilacs bloom on old wood. 2. Providing less than 6 hours of full sunlight in present location. 3. Using fertilizer (don't). If you feed your lilacs, particularly with a fertilizer that has a lot of nitrogen, you will get a large, lush plant but few if any blooms. 4. Wrong soil pH. Lilacs prefer slightly alkaline soil (pH 6-7). Finally, note that most lilacs should start blooming after three or four years but some may take as long as six or seven!

This is a bad time to transplant. Lilacs transplant well IF they are dormant. The best time is early spring before the bush they come into leaf.

The lichen will not damage

By Almanac Staff

The lichen will not damage the bush, but it usually indicates that the plant is older (because it takes a while for lichen to grow). It may be that your lilac is suffering from a disease, such as the fungal disease called Botryosphaeria canker. You might take a sample of an affected branch to your county's Cooperative Extension for diagnosis. Otherwise, you could prune out the dead or dying areas to try to prevent any possible disease from spreading: Every one or two years, prune out about 1/3 of the old wood just after the lilac flowers. Be sure to sterilize your pruning tool with rubbing alcohol after each cut to avoid spreading any disease.

Make sure that your lilac has plenty of drainage and full sun, and that there is no injury along the trunk or branches (such as from a weed whacker).

It is planted on the down side of a huge pine tree in the path of heavy rain run off, but it doesn't sit in water. Any ideas why the blooms are so skimpy?

Too much nitrogen promotes

By Almanac Staff

Too much nitrogen promotes leaf growth over blossoms. The plant might be planted too deeply. Or, the cultivar that you have is not totally hardy to your area. Weather can also be a factor. But perhaps the most likely possibility is that it is not getting enough sunlight; at least 6 hours of sun (8 hours even better) is needed for a good floral display. Lilacs in partial shade may do OK if pruned so that the sun can penetrate the center of the plant. However, if too little sunlight is the culprit, you might consider transplanting the lilac to a site in full sun.

My Lilac was a gift 4 years

By D'dee

My Lilac was a gift 4 years earlier, I transplanted it this spring due to damage @ the base w/much of it dead. The main branch was moved to a sloped area which gets sun/shade. I went on vacation, there was considerable rain, when I returned, leaves were curled, it is still alive tho', I was told it might be infested w/aphids, I sprayed w/Neam's Oil. I'd be sorry to lose this as it was a gift from my daughter. Should I cut it back, transplant it, need help here!

Don't prune or transplant

By Almanac Staff

Don't prune or transplant now. Let the lilac adjust to its new spot. Check for bugs and spray again if needed. The lilac is a hardy plant and will survive if it wasn't damaged too badly.

Hello! I just planted a Miss

By Kristyn

Hello! I just planted a Miss Canada lilac from a 2 gallon bucket to the ground yesterday, and today it is drooping and the blossoms on it are dying. I am worried I shocked it too much and it may die. Any suggestions as to how to keep it going strong? It rained heavily last night during a thunderstorm but I haven't watered it since for fear of too much water. I have it 4 feet from my deck in a sunny location next to a mulched walkway. I am located in Northwestern PA.

By Deloma Lusk

I have a Lilac bush that has been planted for about 6 years, all that grows on it is leaves. It's always had 2 suckers and they are only about 2 ft.tall. Is there something I need to do with the soil to help it grow more suckers and flowers?

If your lilacs are in full

By Almanac Staff

If your lilacs are in full sun and aren't overfertilized, they should flower. To shock your lilac into flowering next season, try driving a spade into the soil around the base of the plants to cut off some of the roots, but not all. Avoid any lawn fertilizer near the root zone. Do not prune. If they don't grow next year, then they need to be in a sunnier spot. Also: If you are pruning too late in the season, they will not bloom.

Have you had any luck finding an answer? I too have a beautiful Miss Kim lilac about 3 years old, lots of healthy leaves but no buds or blooms....maybe the soil is too acid?

By Almanac Staff

Yes, it is also possible that you don't have the right soil pH. Lilacs do not like acid soil. Get it tested. Call your county cooperative extension.

Lack of blooms is usually

By Almanac Staff

Lack of blooms is usually related to lack of sunlight or using nitrogen fertilizer (don't). Another common reason is pruning at the wrong time. If you prune in July or later, you are cutting off next season's flower buds. Just stop pruning. We're not sure where you live, but winterkill of flower buds could be another reason; if so, you need milder winters or a heartier lilac. Finally, it is important that lilacs aren't planted too deeply. The top of the roots should be slightly exposed; pull back the soil if needed.

Hello! I recently moved into

By Flamingo

Hello! I recently moved into a house on Cape Cod. The yard has not been maintained and I just noticed that we have two lilacs on the property. I almost missed them because they are really tall and very skinny! One of them only has one branch and is about 9 feet tall with 3 flowers at the very top!! Should I trim the one branch to eye level like you suggested? Is there any way I can get it to spread its wings, so to speak? thanks for any help!

You need to prune your lilacs

By Almanac Staff

You need to prune your lilacs drastically, to eye level or even lower. After you cut them down you'll get lots of new shoots and these will develop into new flowering branches. You may not have any flowers next spring but the reward will be great the following years.

Here are a few tips. Pick lilacs when the flower cluster is half open. Use pruners or clippers to cut the stem a couple of inches up the center. Put the lilacs in a bucket with cool water covering the stems and leaves all the way up to the flowers. After a few hours arrange the lilacs in a vase and keep them out of direct sunlight.

Korean lilac varieties do not require the long cold periods before flowering that common lilacs do. ‘Miss Kim’ (Syringa patula) is a southern favorite that will do well in Georgia.

No leaves on 2/3 of the canes

My Miss Kim lilac is about 4 -5 yrs old and has always bloomed well. This year 2/3 of the plant didn't leaf or bloom but there is a small bud on the end of each cane ( branch). Are they dead or dying? What should I do?

I'm in a similar situation as

By Spunky Monkey

I'm in a similar situation as this poster.

I have Korean lilacs that have performed beautifully the last 5-6 Springs. Now, all of a sudden, they are not doing so well. There's about 1/3 of the blooms, they are not leafing out as they should, and I have buds but no flowers. I've check for dead wood - although there is some, it's very minimal.

I have pruned sparingly in the past after flowering, but I did not do so last year. We had drought conditions last summer, a late & wet spring, and some late frost. We haven't mulched but my hubby did build up some soil around the base of the foundation, and this is a foundation shrub.

My neighbor's Korean lilacs did beautifully this year, and she has the exact same plants from the same nursery with the same exposure and similar heavy clay soil conditions.

I intend to cut out dead wood and prune back all flowers and buds as recommended, plus fertilize which I also haven't done this year. I'm hopeful that will help. However, I am concerned because of the lack of leafing. Is something else going on?

Any advice, ideas or recommendations are welcome.

Thank you.

Miss Kim's blooms are pale this year.

By Anonymous

Usually our Mss Kim has gorgeously colored fragrant flowers, but this year although prolific as usual, they are very pale in color? Lack of water? Too much fertilizer from the lawn it borders? The whole bush is pale and only the north side borders the lawn. Missing a nutrient? Is it just getting old? I planted it about 13 years ago. I would welcome any ideas.

wilting

By tagg

I live on the Oregon coast (zone 8a I believe) very near the ocean. I got a nice sized Ludwig Spaeth Lilac in 2.5 gallon container. It has been planted for almost 2 months and doing great and now this week it looks wilted. It's all droopy and all the new leaf buds have turned brown. It gets full sun. We have not had rain for two weeks so I've been watering every other day. I was told here the windy salt air dries out plants and they need more water. I may have over watered it? I'm hoping that's it and it will recover. All my neighbors have lilacs in full bloom right now. I wasn't expecting blooms, but I don't want to kill it. thanks.

lilac in pot

Is it draining properly? I have an all-container garden and struggle to learn what needs just how much water/drainage. Drainage usually fixes my problems. I mix in some vermiculite and/or sand to lighten it up some and make sure the container has holes in the bottom. Watering without a mess gets tricky, but i've found a nice middle ground.

Just remove the spent blossom and wait another year to prune. The lilac is still young and will spread on its own.

By Almanac Staff

Yes, you can leave the lilacs in the pots. Keep them outside in full sun during the summer. Make sure to water them so that they don't dry out. Add a little fertilizer (10-10-10) to the pots. If they have grown bigger you can plant them in the fall.

Blooms

I planted a lilac in Indiana that I bought from a nursery in Ohio 3 years ago in June. The last two years it has been covered in buds but they never actually bloom. I thought last year it was because we had a freeze after it budded but this year all we had was a little frost.

The freeze last year probably killed your buds. The frost this year may have delayed the blooms and you may still get some blooms when you have a nice stretch of warm weather.

LOTS of full grown suckers

My lilac bush has probably 20 to 30 suckers that have grown. Should I cut some back? I live in Missouri. It's also so tall the limbs aren't straight up. Is there a way to attach a photo on here?

You need to cut some or all

By Almanac Staff

You need to cut some or all of the suckers out and prune some of the limbs by about half to maintain a good shape. We recommend to prune 1/3 of the bush each year to still have some flowers in the spring and to bring the bush to a manageable size. Prune right after the flowers fade this spring.

Less Blossoms each year

Have an old lilac bush (6 to 7 feet tall)that seems to have less blossoms each year. Should it be trimmed down and if so how much and when?

Prune the bush after this

By Almanac Staff

Prune the bush after this year's flowers have faded. Cut about 1/3 of the shrub's stems down to about 3-4 feet. That will keep the plant rejuvenated. Next year cut another 1/3 of the stems and keep doing this each year to keep the bush flourishing and manageable.

Will suckers prevent my grass from growing?

By Anonymous

I have a suckering lilac in a large garden and I want to keep the lilac but remove the rest of the garden and put in grass all around it. I figured that to get the soil primed for grass growth I would dig up the soil all around the lilac. I have realized that I'm cutting a bunch of roots from the lilac bush, is this OK? Also, if I plant the grass will it help prevent suckers from sprouting up to the surface? Or will the suckers and the intense root system prevent my grass from growing? Many thanks.

Leave a small area around the lilac without grass. Add mulch to this section to keep moisture in the soil and help keep the suckers from growing. It will also make it easier to mow the lawn around the lilac.

HELP! When to Transplant?

By Anonymous

Hi! I have a lilac bush that is about 4 years old & hasn't ever bloomed. I planted it when it was very small (like a stick). I read your comments above about adding Lime to the soil (which I plan to do), but I think I may need to move it to a sunnier location. Is there a best time to transplant a lilac bush (i'm in IL, south of Chicago)? What about pruning, when is the best time to do that? Also, i'm not familiar with lime. Do you have a brand or type of lime I should be looking for? Thanks for your help, much appreciated!

Spring or fall are the best

By Almanac Staff

Spring or fall are the best times to transplant trees including lilacs (fall is preferred). Lilacs don't need annual pruning. Prune lilacs after they have bloomed in late spring or just remove the spent flowers. If your lilac doesn't bloom this year you can wait to prune.
Add ground limestone or hydrated/slaked lime to your soil. Good luck!

Lilac not leafing out

By Anonymous

I planted three lilacs last fall and carefully researched the needs and requirments before planting. Two have leafed out and seem to be thriving, however, the largest of the three still hasn't started to leaf out and it is mid-April here in southern illinois. I have broken a small twig off and the plant is still green inside but it is refusing to leaf out. If it's just being slow how long could it take to show signs of life?

Assuming everything else is

By Almanac Staff

Assuming everything else is equal (soil, moisture, overwinter)—and it sounds like it is, it's hard to tell how long it could take. Certainly if your other two plants and every other one that you see in town is in leaf and this one is not, consider consulting the source from which you acquired the lilacs.

By Almanac Staff

We also love the fragrance of lilacs! The fragrance is from the blooms, so you'll have to wait until next spring. To ensure you have blooms next year, be sure to prune at the right time--AFTER flowering. Lilacs bloom on old wood. The flower buds are set during the summer for flowers the following spring. Therefore, prune within six weeks after bloom so you give your lovely lilac time to grow new wood and buds for the next spring season.

Is it OK to transplant Lilacs in Spring (in New Hampshire)

By Anonymous

We have to burn a house to the ground. There are very mature lilacs and other flowering trees around the house that will die from the fire. We were told by a local gardener that there is no way we can salvage these plantings and we should just let them burn. Our local nursery manager told us that we could move them, but there is a chance there may be some damage and that they probably will not bloom this summer. I think its worth it to try to save them? What do you advise? Is the gardener that told us she wont move them wrong?

By Anonymous

I had two "Miss Kim Lilac Bushes" that I had for three years and they always bloomed profusely. When we moved...I dug them up and took them to my new house. The first year after replanting..I got a few flowers on each bush. But in the last two years, I haven't had one bloom. The bushes are healthy, get the right amount of sunlight and the bushes are only 6 years old. I wonder if moving them, did something to cause them not to bloom. I wish you the best of luck with your lilacs.

Based on what you have told

By Almanac Staff

Based on what you have told us, you could try digging up the lilacs and transplanting. If they are large and old, it may be difficult; transplanting could remove part of the root system which is stressful to the plant. However, it can be done with care. Be aware that it may also take 1 to 3 years for it to recover and bloom. If you do it, the timing must be right: when they are dormant in early spring BEFORE the plant leafs out. In general, small lilacs do transplant well as long as they are not coming into leaf. We hope this helps.

By Almanac Staff

A gem of a lilac! Ideally, lilacs prefer to be planted outside to truly thrive. They can grow in pots though. In terms of fertilizer: do not overdo it. A little phosphorus is fine but nitrogen feeds foliage instead of flowers. I am unclear as to the size of your lilac but can tell you that a 4-inch container is good for starting a cutting (one per pot) and they you'd want to move to a 1-gallon container by late summer. Hope this helps.

No Blooms??

I have had my (2) Lilac bushes for 4 yrs now and they have not bloomed at all. I planted them when they were very small and now they are about 3' high with beautiful green leaves, but no Lilacs. I need to know what to do with them to get them to bloom.

See some of the advice above

By Almanac Staff

See some of the advice above and also the questions and answers below. It may take a few years for a young lilac bush to bloom. Add some lime and compost to the soil this spring and make sure that the bushes get plenty of sun (afternoon sun is best). If the bushes are close to a lawn that is fertilized they may get too much nitrogen from the lawn fertilizer. Nitrogen promotes leaf growth.

lilacs for warm climates

By Almanac Staff

Some lilacs (genus Syringa) are hardy to USDA Zones 8 or 9, but we haven't found any information that indicates that these would flourish in Zone 10. We suppose that it might be possible for lilacs hardy to Zone 9 to get by in a protected area of Zone 10, given the right conditions. However, we'd suggest that you contact your county's Cooperative Extension to find out if there are certain cultivars that can survive in your area.

As an alternative, there is a bush called "California lilac," which is actually a different genus called "Ceanothus." These have fragrant flowers which resemble those of Syringa lilacs. There are a few species and cultivars of Ceanothus available that do fine in Zone 10. The Cooperative Extension or a local nursery should be able to recommend varieties that will thrive in your area.
