Where to buy lilacs: Burpee Gardening

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."

Transplant lilacs when they

By Almanac Staff

Transplant lilacs when they are dormant (not coming into leaf.) The best timing is early next spring before the plant leafs out. Or, you could try fall after all the leaves are dropped. Dig them up on a cloudy, cool day and toward evening. Be sure to get the full root system and don't plant too deep. Water them in well with a water-soluble fertilizer.

By Ted Veremeychik

My dwarf lilac is failing (in NY). 'twas once a beautiful healthy bush but now 'taint. Many branches have become brittle while others are okay. Extensively covered with lichen. It sits in a bed of pakasandra (sp?). Can/should I prune the dead or dying or is this a poor soil issue? Some beautiful blooms appear and even on some of the dying branches. HELP!

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).

I have had my lilacs for many

I have had my lilacs for many years. Over 5 or so years all 3 of my flowers have turned white. Why is this happening? And is there anything that I can do to turn them purple again?

A purple lilac variety may

By Almanac Staff

A purple lilac variety may have been grafted onto white rootstock and sold as a purple lilac. Over time the white flowers from the mohter plant appear.
Sometimes the flower color changes a bit when the soil pH is too low or high. Lilacs need 6.0 to 7.5 pH. Test your soil and amend accordingly.

We have a lilac bush that is

By abs

We have a lilac bush that is about 5 years old. We live in NY and every spring it is loaded with blooms, but they are skimpy..you can't even see them. They open up but don't look like much. The bush has grown nicely since planted and it is lush with leaves. It gets at least 5 hours of morning sun. 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

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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 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.

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?

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.

Plant the suckers in 1 gallon pots. Use a good potting mix and keep the soil moist. You can add a root stimulator but often the suckers will start growing without any help. Good luck!

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.

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.

When I lived in the north bay area, north of San Francisco, I was told we need to put a bag of ice at the base of the lilac in the winter at least once, since it needs a cold season to bloom properly. I did this and my bush flowered fine.

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.

Deer Resistant?

By Almanac Staff

Though NO plant is truly deer-resistant, lilacs fall into the "Seldom Severely Damaged" camp so they're a good choice. As far as a fence goes: Deer will usually chose a different plant to eat, however, all bets are off in a very severe winter so it depends on your climate.

By Almanac Staff

Northern lilacs need a long period of winter chill in order to bloom well. Your area may not have enough cold days.
There are some lilac varieties that may bloom in Texas. ‘Blue Skies', ’Angel White’, 'Lavender Lady', ‘Superba’ and ‘Miss Kim’ are just a few. Search for low-chill lilacs to find mail-order sources.

Dwarf Tinkerbell lilac

By Anonymous

I ordered one of these plants, received it about a month ago (mid October). It has two shoots off the main stem, each with two leaves and tiny buds in the "joint" It shows no sign of preparing to bloom...it's in a container, watered from the base, medium sun. How long before I'll see signs of blooms?

Tinkerbelle lilac

By Almanac Staff

The 'Tinkerbelle' lilac is bred to be hardy from Zones 3 to 7. It blooms in mid- to late spring. Although a dwarf, it reaches about 4 to 6 feet high at maturity, with a similar width. If you are planning to wait a few years before planting the lilac in your yard, make sure that you provide a large container for the growing lilac.

What year the lilac will start to bloom will depend on the age of the plant, as well as other factors, such as climate, cultural conditions (soil, light, water, temperature), pests/diseases, etc. You might ask the nursery from which you ordered the lilac as to what age the plant was when it was sent in October, and if they expect it to bloom starting next spring, or if it needs to age a year or so before it is ready to flower. Some lilacs will not start blooming until they are about 3 to 8 years old.

By Almanac Staff

Leave the lilacs outside. Depending how severe your winters are you may need to add some mulch around the pots. You can also dig holes or a trench and put the pots in the ground. Cover with soil and let go dormant. In the spring you can remove the pots and plant the lilacs in permanent spots.

If it is a lilac variety that is cold hardy it will need to be stored in a cool place (unheated garage is perfect). You can also dig a hole in the ground in a protected area of your yard and place the pot in the hole and cover it with mulch.

Non blooming lilac

Add some lime to the soil

By Almanac Staff

Add some lime to the soil around the lilac now and then again in the spring. Also make sure that the bush gets plenty of afternoon sun. If the lilac is located in a lawn area that is fertilized the roots may get too much nitrogen which promotes leaf growth.

By Almanac Staff

If you have dark black streaks on a young lilac, then you probably have lilac bacterial blight. It overwintered on the wood 1. Prune and burn all infected parts asap. 2. Provide good air circulation; make sure the leaves don't rub against another plant. 3. Do NOT fertilize. High nitrogen in young plants favors disease development. 4. In early spring, spray copper sulfate. 5. Purchase blight-resistant varieties.

lilac bush dying?

By Anonymous

hi there.we have an approx. 10 foot lilac bush in our backyard that gets full sun. No idea how old it is. We've lived here for 2.5 years and it's always been pretty sparse looking. there are few branches and even fewer with leaves. Right now the top foot is full of lush green leaves, the middle has light green-yellow leaves that are turning brown and falling off very easily. The bottom portion has a few healthier leaves. i noticed that there where several large branches from the ground that were completely dead so started to cut them back and they pull right out of the ground! When it does bloom it only has maybe 12 flowers and they don't last long. What should we do? It's the end of August and has been a very hot summer. Thanks in advance!

Lilac bush

By Almanac Staff

Your lilac bush will benefit from some pruning. You can cut the entire bush back to about a foot tall in the early spring before new growth starts. This will rejuvenate an old/overgrown lilac, but it will not bloom until the following year. Or, you can try the 3-year plan to keep some blooms going. Take out a third of the bush each year by cutting the large branches to the base of the plant. Be sure to prune in early spring before new growth appears.

It is drastic but lilacs are very hardy. See our pruning tips above. A less drastic method is to prune 1/3 of the bush in early spring. The following spring cut back another 1/3 and prune the last 1/3 the third spring. See our pruning pointers above.

Lilac leaves turning brown and curling inward

By Anonymous

In May we planted three lilac bushes on the west side of our house, usually gets about 6 to 8 hours of sun. They seemed to be doing fine until about a month ago, and I have noticed that some of the branches appear dead and are not bearing any leaves. Also, some of the branches have leaves that are browning around the edges and curling inward. We are in Columbus Ohio, and I am not sure when I am watering too much or when I need to water more frequently. Is it me or did we get unhealthy plants?

Lilac leaves

By Almanac Staff

Lilacs are usually not fuzzy about the soil but you may be lacking magnesium that they need (symptoms are brown curled leaves). Or you may not be watering enough. During dry hot weather the bushes need frequent deep waterings. Use a hose and soak the soil around the bushes a couple of times a week.

If it's a white, moldy look,

By Almanac Staff

If it's a white, moldy look, then it's powdery mildew. Don't worry. This is common on lilacs and often arrives in late July or August. It doesn't harm the plants and it will be gone when the leaves drop after a few frosts. Next year: To keep under control, spray before the disease shows up. (Consult with your local garden center on sprays.) In terms of the branches: Are they dead? Cut the old, dead branches out completely back to the ground. This will also help with the mildew by improving air circulation.

Wilting leaves ...

I received a healthy lilac bush for a gift. It was doing fine for a week or two in a container. After planting, almost immediately the leaves started drooping and have continued to get worse. It's super hot and dry right now, and I've been trying to balance watering enough w/not watering too much. But it's not looking good.

Your lilac is probably

By Almanac Staff

Your lilac is probably experiencing transplant shock (lilacs are best planted when they are dormant). To help your plant, keep watering when the soil gets dry (not too wet, not too dry); make sure that it isn’t planted too deeply; and provide good drainage. Water from the base; water will burn leaves in hot, sunny weather. Do not fertilize the first year. Provide light shade during the hot weather the first year so that the plant won’t lose as much water as its roots establish themselves; you can create shade by securing burlap to stakes and setting these temporary walls on sunny sides of the plant. Burlap allows some sunlight to penetrate so that the leaves can make food, but the light shade helps to reduce evaporation.

Hot weather can cause brown leaves. Water the lilac deeply once a week and add 1/2 cup of lime around the base of the tree to sweeten the soil.You can prune some of the old branches. This will encourage new growth.

Brown leaves

I too have the same brown leaf issue in coastal South Carolina. My lilacs are not in the ground. They are in a large jack daniels barrel and though some of the older canes have a few wilted leaves, the plant is still sprouting new canes and the old canes show new leaf buds. My parents brought these lilacs from Bucks County, Pa to Richmond, Va in the late 70's and I brought some to South Carolina when I moved from Richmond. Excited about new canes but not sure what to do (if anything) about the wilting. Been humid, hot, and lots of summer storms here this season. I'm going to try to pull the barrel under the porch during next few rains to try to dry the moisture-heavy soil a bit and just put it out in full sun when not raining. Should I cut old canes or just let it roll?

Brown leaves

By Almanac Staff

In wet weather lilacs get a fungal disease that causes the leaves to wilt and turn brown. The lilac will recover from this when the weather improves. Let the soil dry out. You may want to prune some of the old canes to encourage new growth.

Make sure your plant is receiving lots of sun. We recommend pruning in in spring.

Any of the suggested tips in the 'Pruning' section above will be helpful in trying to get your plant to successfully bloom. You may want to start fresh by cutting down the plant to about 6 inches in height and "start over." However, this will also take a few years of patience while waiting for blooms.

Cutting lilacs down

Our lilacs are 5-7ft high and I want to cut them much lower and promote more growth next year. My wife insists that the "insides" are all just wirey and says we should just cut them down and replant new. I say cut them low and they'll regrow anyway. Are EITHER of us right?

I hope it's OK with your wife

By Almanac Staff

I hope it's OK with your wife is we say that you are right! Lilacs are very hardy and they regrow (as long as they're not dead). You can either: 1. Cut the bush back to short stubs (about 6 inches long) in the early spring before new growth. It will rejuvenate an old/overgrown lilac, but it not bloom until the next year. 2. OR, try the 3-year plan to keep some blooms going. Take out a third of the volume each year by cutting the large branches to the base of the plant. Be sure to prune in early spring before new growth.

By Almanac Staff

Although yellowing leaves can be a sign of one of several problems, our best guess would be overwatering. Too much water can rot lilac roots, which in turn causes yellowing leaves. In general, lilacs don’t do well in wet areas.
When planting a lilac, make sure that the area has good drainage, air circulation, and sunlight. Water the lilac immediately after planting, and then 2 to 3 times per week for the first month. After that, provide about 1 inch [about 2.5 cm] of water per week (just one deep soak once per week is good, to reach the lilac’s deep roots). Water a little more during hot weather.

A very old lilac

We have a very old lilac and it's main stem is on it's side and others are coming out of it. It has one other main stem about 8 inches away. Almost like two plants. They reach up to just under the second story window in the dining room. It looks like it was chopped down at one time to about 4 feet, then all the rest of the growth on top of that. How would you prune it since it is already July 4th? Is it too late to prune this year to still have flowers for next year? It is my mother-in-laws and she is 92. She would probable get upset if it was too drastic. but whatever if it needs it.

Old Lilac Care

By Almanac Staff

For your old lilac tree we suggest a three-year plan. This allows the lilac to bloom every year. In late winter of year one remove one-third of the old canes (down to the ground), remove half of the remaining old wood in year two, and the rest of the old wood in year three. Then, follow a normal pruning schedule. Every spring 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.

The "bloomerang lilac" can be planted like any other container-grown shrub. Lightly fertilize with organic seaweed extract, fish emulsion, or slow-release fertilizer in early spring and again after the first (mid-May) bloom. And lightly prune after each bloom. Both of these techniques will encourage more blooms. It's a dwarf shrub variety -- about 4 to 5 feet diameter -- which is helpful to reach the flowers at the top for pruning! All the best.

I didn't think that lilac root systems were deep or invasive. Do I need to be careful how close to plumbing pipes I plant the lilacs? thank you!

You are correct: Lilac roots

By Almanac Staff

You are correct: Lilac roots aren't that invasive though they can ramble and lilacs need room to grow in all directions. You shouldn't have to worry about foundations or pipes. We advise folks to plant the lilacs about 12 feet or more from a house foundation if they wish to avoid worry. The roots are about one to one-half times the length of the branches. A 10-foot shrub would have roots about 15 feet in every direction.

A lilac is fine in a container for the short-term, given plenty of water and sun. However, after a year or two, they'll get too large and they'd do better in the ground. In a pot, the lilac will also need fertilizer in early spring and after bloom--and also add a handful of lime once a season.

Suckers are plant sprouts

By Almanac Staff

Suckers are plant sprouts from the root system. New lilac suckers grow into new lilacs! For some folks, this is desirable. For many homeowners, who don't want more growth, it is not. Your lilacs also need pruning. If you just have blooms on the top, then your lilac is overgrown. You must prune RIGHT after they finish flowering this year, and before mid-July. If overgrown, also cut down about a third of the older canes as close to the ground as possible next bring before they leaf out. You may not get blossoms that year but you'll send out new growth and the shrub will start to look better next year. Always thin out your thickest canes as low as you can cut them.

Black leaves may mean: 1)

By Almanac Staff

Black leaves may mean:
1) Frost injury on newly emerging tissue. If the black parts on more prominent on the margins of leaves, it's probably just the cold temperatures.
2) Lilac blight. This looks a bit different--starting as brown water-marked spots and progresses to blackened leaves. A cool, wet, rainy, spring season can lead to lilac blight, especially if rainy after a late frost. In this case, you want to prune and burn all infected areas.
You may wish to bring a sample to your local cooperative extension or garden center.

This drawf is 3 years old and has about ten 18" suckers growing I want to transplant them but need advice too. Hope someone has the answers, thanking you in advance.

Lilacs are relatively low

By Almanac Staff

Lilacs are relatively low maintenance, just be sure to trim the blooms after they’ve expired in the spring. Lilacs grow on old wood. The seeds should just be cut off, planting them will most likely get you nowhere. Also cut away the suckers. Lilacs are clump forming and produce new shoots from the base of the trunk. Use these shoots for propagating lilac bushes. Dig down from the main clump, exposing the roots and carefully cut the shoot away from the “mother” plant. Make sure you include roots. Then plant the shoot in a suitable location and water regularly until it takes hold.
Good luck!

I live in northern Alabama and planted a lilac bush about 4 years ago. It bloomed the first year, but although it is growing in size, it has not bloomed the past 3 years. I have tried everything, including soil acidifier. I was really hoping it would bloom this year, as I had been doing research on how to prune. But it never did, and now I'm not sure which canes to cut back, as I have read that you should only prune the canes that have produced blooms in spring. The only other thing I can think of is that I have not removed the grass and mulched around the bush. Could that really be the reason for its not blooming?

By Almanac Staff

There a few things that could be going wrong:
Check your soil’s acidity. Lilacs prefer soil pH from 6 to 7. You can find soil testing kits at most garden centers.
Perhaps your lilac is not getting enough sun. Lilacs need at least 6 hours of sunlight per day.
Lilac bushes tend to not bloom for the first few years, though it sounds like you were lucky to have blooms in year 1. They spend the first 3 years getting established and start to bloom regularly by age 6.

Bees are eating my lilac leaves

By Anonymous

I live in Tucson and have two lilac in large pots. Each year about May they get many holes in their leaves about the size of a quarter. We have seen bees cutting away the leaves. Is this damaging to the plants and is there anything to prevent it?

leafcutters?

By Almanac Staff

Are the holes round and perfectly shaped? If so, they are not honeybees or your traditional bees. As you live out West, you may have "leafcutter" bees. The damage is only aesthetic and minor as they're just cutting bits of the leaves for their nesting. They are not aggressive with humans. Importantly, they are valuable pollinators for your garden so we'd leave them be. Pesticides don't work and their nests are hard to find so you don't have much choice.

I have a lilac bush that my aunt gave me a long time ago. The bush is probably 10X10ft. It's at my childhood home where my brother lives. You have inspired me to go dig up some of the suckers to plant in my yard . I will wait until Fall to do so as I think it may be too late now. I'll be going for the 4 ft or taller suckers on the outskirts of the main plant. Again, thanks for sharing your knowledge and letting us all know how easy it is to grow these beautiful plants. They have been my favorite since I found them as a small child in my aunt's yard.

Lilacs not in South

By Anonymous

Being from Illinois, the one thing I miss in spring is the Lilacs. South Alabama is no place to grow them, all Northerners enjoy!

Lilacs

I live in South Carolina and have a lilac bush in my yard. It blooms in April every year. I don't understand why you say South Alabama is no place to grow lilacs. I have even separated my bush and replanted it with great success. Have you tried growing lilacs in Alabama? If not, you might want to give it a try.

will my plant die?

the next door's workmen have hacked at my lilac plant and its in a right mess, if i up root it to re plant it, will it grow ok?

Hacked Lilac

By Almanac Staff

If the roots are still in the ground, leave it. Lilacs are very tough plants and should survive. You may see some growth but not blooms this year. Cut out any hacked stems. Unfortunately, this would be a bad time to replant. The best time is early spring and the next best time is the fall after the leaves have dropped. Wait til then if you can.

early spring sun only?

By Anonymous

I want to plant a lilac bush in a spot where it will have full sun in winter and early spring, but only partial after mid-May. This means it will have good sun through it's blooming season (I am in the north east), but then less through summer and fall. What do you all think? Enough sun? Thanks!

As long as they get 6 hours

By Almanac Staff

As long as they get 6 hours of sun through the end of their blooming season, they should be OK. They really need the sun to bloom profusely.

Color variations

We've taken shoots from the same original purple lilac bush over the years and planted them in different places through out the property, all in full sun. But the blooms of each new bush seem to be a shade or 2 different than the parent, some darker, some lighter, some redder. What causes this?

Would lilacs do well in an area like Houston Texas. Not too much chill here, even in the winter.

lilacs for texas

By Almanac Staff

Some of our readers have had success with the 'Miss Kim' lilac and the Persian Lilac (Syringa persica) as they are low-chill hybrids. However, it's not a sure bet because lilacs just love that long winter chill and simply aren't native to this area. Here are some possible substitutions: Crepe Myrtle, Texas Mountain Laurel, and the Lilac Chaste Tree (Vitex agnus-castus).

Lilacs don't change color based on the soil or surroundings (unlike hydrangeas and some other flowers).

curling

I transplanted three dwarf lilacs last fall. They all bloomed this spring and seemed to be thriving then the leaves began to curl and one bush died, and the other two are marginal. I sprayed Seven but had no effect. Can you help?

curling lilac leaves

By Almanac Staff

Curling leaves often means not enough water or improper watering. Take a trowel and dig down into the soil below the lilac to if water is getting down deep into the roots. If not, put the hose on and let it trickle for a good 20 minutes as they are thirsty.

Bees

Do lilacs attract bees or wasps? I am hoping to plant my lilacs around our deck to close in the bottom, but i don't really want to be fighting the bees and wasps all summer and not be able to enjoy my deck.

Lilacs and bees

Yes, lilacs do attract bees (and wasps). They have nectar-rich blossoms. Consider foliage plants instead.

My lilac bushes don't have enough leaves???

By Anonymous

I planted 50 lilac bushes 7 yrs ago, they were in an area where they got little water in summer, they look meager and a bit sparse. How can I make them produce more leaves for a full or lush look?? I recently transplanted all of them to our new home since the buyer didn't want them. They are 3-5' tall. Will severe pruning cause them to " flesh out"??

Prune your lilacs properly

By Almanac Staff

Pruning is the best way to rejuvenate lilacs. The best time to prune is after May bloom but before new flower bud set for next year in early July. Cut out any dead wood and remove the spent flowers. Prune out the oldest canes (down to the ground) and cut back some of the newer branches by 1/3. Do this again next spring and you should see healthier bushes with more leaves and flowers.

tiny blooms

By Anonymous

Why is it that some years there are Huge blossoms on my lilacs and some years like this year, they are tiny?

Tiny blooms

By Almanac Staff

The size of the flowers may be caused by the weather this past winter and early spring.
Too much nitrogen in the soil can also cause poor blooming. Use a fertilizer high in phosphorus. A tip from the Almanac archives is to spread your fireplace ashes around the lilac bush for bigger, better blooms.

Question about blooming

By Anonymous

We have had a lilac tree for about 3-4 years now. It has yet to bloom. It's aprrox. 7' in height. After we bought it and planted it, we found a better spot for it so decided to transplant it. I thought perhaps it was in shock. The leaves look great as does the tree itself. Any help would be greatly appreciated. I have no idea what kind of lilac it is though. Thank you in advance. Lesley

Lilac not blooming

By Anonymous

I had the same problem. Lilac plant beautiful but would not bloom. I removed trees that kept the lilac in the shade and
fed it lots of lime. The next year it bloomed.

why lilac is not blooming

By Almanac Staff

If your lilac plant is only 3 to 4 years old and you have never seen blooms on it, it may not be mature enough to produce flowers. You may need to be patient and wait another year. Or, it may be due to other factors. Does your new location have full sunlight and dry soil? No sun, no blooms. Did you plant too deep? Is it the right type of lilac for your region? Are you using a fertilizer with too much nitrogen? And you pruning incorrectly--see this page on how to prune lilacs so that you do not remove its very buds for next next year's growth.

Given the heat, try Persian lilac or Chinese lilac. They are low-chill lilacs (which normally need a chill) and best for desert areas.

clay and dirt

By Anonymous

I bought a Charles Joly lilac bush from a nursery and was ready to plant it, but when I started to dig the whole, I found that about a foot into the dirt, I hit clay and rock. Now I'm afraid to plant it there. Although there are trees and bushes growing all around. Should I find another place?

planting lilacs in clay

By Almanac Staff

Lilacs are actually one of the plants that will tolerate clay soil with a pH of 6 to 7. Working compost in with the soil will help provide nutrients.
In terms of proximity to other trees and shrubs: Be sure they are spaced properly. A Charles Joly Lilac is a medium-size lilac shrub and should be spaced 4 to 7 feet apart to allow it to spread. Also, lilacs prefer 5 to 6 hours of sun so you don’t want them shaded by other trees and shrubs.

Dead buds?

I am not sure but my lilac has dry ends on 3/4 of the stems this year-I have had them before-it visually looks like a spent bud-open with nothing in it-they snap right off-I don't know why one has to trim back the spent flowers every year-My aunt has been gone for many years-she always had large full lilac bushes-they are still that way at her place-house is gone but lilacs are still there-never get pruned or treated in any other way-they are gorgious-I even took one to plant at my home-whats up with the dry ends and whats your feelings on my aunts lilacs-never been touched-

Mild winters and few blooms

By Anonymous

The past few winters have been very mild (I'm in Maryland, zone 7a) and my lilacs are barely putting out any flowers. Is there anything I can do to encourage blooming despite this?

Lilac Bloom

By Almanac Staff

There are five main reasons that lilacs fail to bloom: insufficient sunlight, too much nitrogen fertilizer, improper planting (planted too deeply), improper pruning (pruning at the wrong time) or winterkill of the flower buds. Also, lilacs will typically not bloom the season after a harsh pruning, so you may need to wait until next year before you see flowers. If nothing works, you might take a sucker from your lilac bush and try growing it in a new location.

When & which ones to plant

We are outside Philadelphia & want to plant lilacs Any suggestions as to which types work bests & when is then best time to plant?
Thanks

Lilac varieties Philadelphia PA

By Almanac Staff

On variety, it depends on whether you want a tree, shrub, border, etc. A classic is the common lilac (Syringa vulgaris). It's 7 to 15 feet tall and spreads 6 to 12 feet once grown. For a smaller lilac, consider the Persian lilac tree. Then there is the ‘Miss Kim’ (Syringa patula), a hardy compact shrub (five feet high by five feet wide). April and May are good times for planting. Enjoy the lovely lilac blooms!

My Mom has a lilac bush that has been near her bedroom window ever since I can remember it must be at least 50 years old?. We are selling her house but I would like to know if you can take a cutting from this and plant in my yard to remember her by?

Old Lilacs

By Anonymous

Established lilacs such as this will have smaller off shoot plants growing around the perimeter of the bush. You can easier dig up some of the smaller lilacs plants growing around the main bush. The roots are not very deep - less then 6". Don't feel timid to only dig up a lilac plant that is a foot high - you can easily replant ones that are 3 to 4 feet high - just looked for slender upright growth.

These replanted lilac bushes will be smaller and resemble a small flowering tree until they begin to fill out over the years.

I moved an established lilac bush which was over 6' x 6' without in sections without damaging it (it was over 20 years old). Lilacs are really a single bush but a cluster of bushes which lend themselves to be relocated in desired.

The usual reasons that I lilac languishes is: too much shade or too much nitrogen. Move the plant if needed and make sure you fertilize correctly. One way to get your hydrangea blooming is to drive a spade into the ground around the lilac--about where its foliage ends. Do this in a circle around the lilac about 6 times.

By Almanac Staff

According to some sources, it may take up to 7 years after being transplanted for lilacs to bloom. Also, lilacs should be pruned in the spring, immediately after they blossom. If they are pruned later in the summer, you may be cutting off the new growth that has the flower buds for the following year.

lack of bloom

my tree bloomed tons last few years, everyone else's are flowering but mine won't even show buds. Help. I love these plants and want flowers

lack of bloom

By Anonymous

I had the same issue with two large bushes both over 10 years old. Both had robust growth in years prior. Last year I was away for their blooming season and missed out on the amazingly fragrant flowers which I always cut to put into vases for myself and all my friends since there was always so many.

I suspect the low flower rate this year was caused by the fact that I did not cut the flowers the prior year and I didn't prune back after the flowering.

cut spent blooms

By Almanac Staff

Also, be sure to snip back the spent blooms right after they fade (back to the leaf, just past the bloom). This can take a while but it will rejuvenate your lilacs.

lilacs not blooming

By Almanac Staff

The most common reason lilacs stop flowering is pruning at the wrong time of the year and too much nitrogen fertilizer. Lilacs flower on wood grown the previous season, so any pruning must be done immediately after the shrub blooms. Pruning in summer or fall or early spring will remove flower buds. Prune as directed on above page and withhold fertilizer.

we planted our bushes 2 years

By Anonymous

we planted our bushes 2 years ago and had a frost i mistakenly covered them with black trash bags and they burnt since then the bushes look very healthy but have never bloomed will they ever?

Lilac Care

By Almanac Staff

Some varieties of lilacs need a few years to mature. Other reasons for not blooming: A late freeze, too warm a winter (lilacs need chilling), lack of sunlight (6 hours of full sun needed), overfertilizing (not needed), soil that's too acidic (get a soil test and amend with lime if needed), and incorrect pruning (the most common mistake). Pruning helps a lilac flower. Avoid drastic pruning while your lilacs recover. See the pruning tips above.

Lilac roots

By Anonymous

How big do the roots get? Can I plant it next to my house near my bedroom window?

lilacs near house

By Almanac Staff

Plant the lilacs about 12 feet or more from the foundation to avoid worry. Lilac roots aren't invasive though they can ramble and lilacs need room to grow in all directions. The roots are about one to one-half times the length of the branches. A 10-foot shrub would have roots about 15 feet in every direction. However, the roots aren't invasive and don't worry too much about foundations.

lilacs and frost

By Almanac Staff

Most lilacs are quite cold hardy (to USDA zone 2) and the plant itself will be fine. However, if you have buds already (given this strangely warm winter), you can throw a cloth sheet over the bushes if they're not too big. The buds are damaged easily. Either you'll lose the flowers totally or the panicles will not be filled out---dead spots, a few flowers, etc.
