With immense billowy blossoms, hydrangeas flaunt an old-fashioned charm that is hard to resist. Colors also beguile with clear blues, vibrant pinks, frosty whites, lavender, and rose—sometimes all blooming on the same plant!

The colors of some H. macrophylla  flowers are affected by the relative availability of aluminum ions in the soil. Acidic soils with a pH of less than 5.5 produce blue flowers; soils with a pH greater than 5.5 product pink flowers. White flowers are not affected by pH.

Unrivaled in the shrub world, these elegant ladies are easy to cultivate, tolerate almost any soil, and produce flowers in mid-summer through fall (when little else may be in bloom). Hydrangeas are excellent for a range of garden sites from group plantings to shrub borders to containers.

Planting

  • Most hydrangeas thrive in rich, porous, somewhat moist soils. Add compost to enrich poor soil.
  • They prefer full sun in the morning, with some afternoon shade; however, many will grow and bloom in partial shade. This is especially true for the bigleaf hydrangeas (see Recommended Varieties below).
  •  Plant in spring or fall.
  • Dig a hole as deep as the root ball and 2 to 3 times as wide.
  • Set the plant in the hole and fill it half full with soil. Water. After water is drained, fill the rest of the hole with soil.
  • Water thoroughly.
  • Space multiple hydrangeas about 3 to 10 feet apart.

Care

For the first year or two after planting and during any drought, be sure hydrangeas get plenty of water. Leaves will wilt if the soil is too dry.

PRUNING!

  • When growing H. macrophylla varieties in Zones 4 and 5, don't prune unless absolutely necessary, and then do so immediately AFTER blooming. Otherwise, remove only dead stems in the spring.

If you need to prune an older hydrangea, it depends on which variety you have.

  • The common Bigleaf hydrangea should be pruned AFTER flowers fade (late spring/early summer). If you prune before bloom, you may not have blossoms the following spring.
  • Oakleaf, panicle, and smooth hydrangeas blossom on the current seasons' wood so they should be pruned BEFORE bloom when plant is dormant, i.e. late winter or early spring.

In the fall, cover plants to a depth of at least 18 inches with bark mulch, leaves, pine needles, or straw. If at all possible, cover the entire plant, tip included, by making cages out of snow fencing or chicken wire, and loosely filling the cages with leaves. (Do not use maple leaves.)

Harvest/Storage

Try drying hydrangea flowers to create a wreath or other decorations around the house:

  • Harvest the heads when the flowers have matured and developed a papery consistency.
  • Remove leaves from stems, and hang upside down in a warm, dry, dark, airy room.
  • When completely dry (usually a couple of weeks), store in a dry location out of direct sunlight.
  • To enhance flower color, spritz dry flowers with diluted Rit dye.

Recommended Varieties

There are two main groups of hydrangeas.

Group 1: Plants that bloom on new growth (this year's stems)

These hydrangeas, which form their buds in early summer on new growth, will flower reliability each year, requiring no special care.

  • Panicle hydrangeas ( H. paniculata) are hardy to Zone 3 and boast fat, cone-shaped flower heads. They are a good choice for a beginner. The most common cultivar is 'Grandiflora', or P.G. (PeeGee) after its initials, a big old-fashioned floppy shrub that is 10 to 15 feet tall.
  • Smooth hydrangeas (H. arborescens) or "snowballs" are excellent for cold climates, flowering reliability in Zone 3. The flowers look like oversized white-flowered pop-poms. Look for cultivars 'Grandiflora' and 'Annabelle' which produce large blooms in late summer.

Group 2: Plants that bloom on old growth (last year's stems)

If you live in Zone 8 or warmer, choose plants from this group.

  • Oakleaf hydrangeas (H. quercifolia) exhibit incredible bud hardiness and thrive in Zone 5. This graceful plant is noted for its spectacular fall colors that range from red to purplish burgundy. The flower heads turn a rich brown that lasts all winter. Try 'Snow Queen', 'Snow Flake', and 'Alice.'
  • Bigleaf hydrangeas (H. macrophylla) are the most common species and come in two flower shapes: Mopheads (or Hortensias) which are hardy to Zone 6 and bear large, ball-shaped flowers and lacecaps which are suitable for Zones 5 to 9 and form airy, elegant, flat-topped clusters of flowers. We love 'All Summer Beauty' (Hortensia) which has profuse, dark blue flowers, pinker on soil near neutral. 'Nikko Blue' (Hortensia) is vigorous, with large, rounded blue flowers. 'Blue Wave' (Lacecap) produces rich blue to mauve or lilac-blue to pink flowers.
  • Climbing hydrangeas are just magnificent, lighting up the trunk of a tall tree. This vine blooms from late June to early July, exhibiting flat, lace, creamy-white flowers against glossy leaves.

Wit & Wisdom

It is possible to change the flowers' colors but not instantly. Color correction takes weeks, even months. It is easier to change blue flowers to pink than pink to blue. Wait until the plant is at least 2 years old to give it time to recover fro the shock of its original planting.

  • Start with the Hydrangea macrophylla variety. Have your soil pH tested.
  • To get blue flowers, you need to lower the pH, which you can do by adding sulfur or peat moss to the soil.  To get pink to light red flowers, add ground limestone only around the plant; a pH above 7.5 will result in poor growth.

Must the Hydrangea be

By steve Nogreenthumb on April 18

Must the Hydrangea be planted? Is it possible to just move to a larger pot?

I have another quick

By justmissjamey on April 15

I have another quick question, I've read the comments and not quite getting it, I have a hydrangea that's 1 year been in ground, and I can see new growth around the ground of it, and its still brown and crunchy looking, should I go ahead and cut the old flowers off of them, or wait a few more weeks until the rest of the plant starts to "green up"??
Thanks, I'm new at this and don't have a natural green thumb, and am so excited to just see new growth on this one, when I have seemed to kill everything else I planted last year. Lol

You can cut the brown flowers off but leave the stems.

Hello all, Was just in cvs

By justmissjamey on April 15

Hello all,
Was just in cvs today (april 15th, in zone 5) and found a beautiful blue/ purplish hydrangea. I am assuming that it is like a regular one and not the plant that is grown indoors and is good for one season, as the tag says it is easy to grow indoors or out in pots, or beds. The tag also says 18 to 36 inches for height and to plant them 24 inches apart. It does not have a name or species. I'm new at this, but I am wondering is it okay to plant it outside in a day or two?? I'm worried because I have seen the weather and there are some nights looking to get down to 28 at night. What can I do, any ideas or suggestions will be helpful...do I leave in it the pot and leave it inside for a couple weeks until it gets a bit warmer, or can I go ahead and plant it in thee ground?? I just could not pass up this beautiful plant, because not only is it pretty, but I only paid 6.99 for it!!! Yay!! Lol. But I don't want to kill the poor thing by putting it in the ground to early, especially since it more then likely has been in a green house, but also the store where it is a lot warmer then it is outside here at nights right now....any thoughts or advice would be great. Thanks :)

Wait to plant the hydrangea

By Almanac Staff on April 17

Wait to plant the hydrangea outdoors until it has warmed up a bit. Keep the plant in a sunny spot indoors until you are ready to plant it outside.

By Jennifer Lee Sims on April 11

Late last summer I bought a pink blooming hydrangea. I'm not sure of the variety but where I bought it told me to plant it in the morning sunlight and with nutrient rich soil so I planted it in my front bed and it stayed good for a whole but died off. I was told it may be in shock and our neighbor who grows said to cut off all the dead and it would grow back but now it's spring and all my tulips have come up but I have yet to see any evidence of my hydrangea. Did we kill it?

Hi Jennifer,
Some hydrangea varieties take a little longer to start growing in the spring. Don't give up yet.

By Crystal L on April 10

My husband and I transplanted several very large hydrangeas. I am not sure what kind they are (I know the flower clusters were round not cone) and they were very large bushes about 4ft tall. They were transplanted in the mid to late summer last year. As of today April 10 they still look woody and brown... Did we kill them? Is there something I should be doing to them to help them? Any help would be greatly appreciated!!!!

where do you prune the old

By gary poinsett on April 5

where do you prune the old flowers off of the stems

Most pruning is carried out

By Almanac Staff on April 6

Most pruning is carried out in late winter or early spring. However, the climbing hydrangea is pruned after flowering in summer. See our pruning information above; you don't want to prune at the wrong time or you may remove the buds for the next season's flowers.
If you just mean deadheading--i.e., pinching off dead blooms, it can generally be done right after the flowers wilt, though some gardeners in northern climates prefer to leave the dead blooms on the mophead hydrangeas through the winter to protect them from frost.

I have a Hydrangea

By hydrangeaquestion on April 3

I have a Hydrangea Macrophylla "Big Daddy" variety. I am seeing a little bit of green at the bottoms of a couple of stems and what looks like some new buds/stems pushing up through the ground, but my question is on my established stems.

There are several brown buds on some of the stems. I don't know if they tried to bud recently and turned brown with the cold, or if they were there when winter started and maybe I just didn't notice/remember.

I don't know whether to prune/shave those brown buds off, or would any new buds maybe break through those and I should leave them alone?

Thanks.

The brown buds are dead. You can remove them or just leave them on the stems. The new growth will cover them up.

Some creature is eating the buds off of my old growth stems on my hydrangeas at night. Would it make sense to cover the plants w/plastic bags at night? I think kitchen size plastic bags (white?) shld be big enough. If I were to leave town for a few days, would it be ok to leave the bags on? The buds arent opening yet. (Zone 5)

It is recommended to transplant hydrangeas in late fall when they go dormant. You can try to transplant the hydrangea as soon as you can dig in the soil (the sooner the better).

Hortensia is a compact bushy

By Almanac Staff on March 28

Hortensia is a compact bushy shrub. We would always recommend that it goes in the ground over a pot, but you can grow them in containers. The size of the container depends on the size of your hydrangea. If it's a small cutting, you could use a pot about 6 inches in diameter. A year-old hydrangea would usually fit in a medium pot about 8 to 10 inches in diameter. After two to three years, you might need a pot about 24 inches across.

I received a Hydrangea

By Rhonda W. on March 28

I received a Hydrangea Macrophylla "Ravel" for Valentine's Day. It was in bloom when I received it. The bloom has since died, but now the leaves ane turning brown and cruchy. It starts at the tip of the leaf and works its way inward,even on the new leaves. I water it every 2-3 days. What could the problem be? Even though it is now March, does it still need to go dormant? If so, do you still water it and how long does it need to stay dormant? Thank you so much in advance for your help.

Hi Rhonda, The smaller

By Almanac Staff on March 28

Hi Rhonda,

The smaller potted hydrangeas sold for special holidays or events have usually been grown in greenhouses for a one-time, spectacular show often at the expense of the future health of the plant. The best thing you can do is to plant it outdoors in the ground or in a big container as soon as possible and keep it watered. See our planting instructions above. It may come back and show new growth.

When is the best time to begin to fertilize a Hydrangea to get blue flowers? I live in Zone 5 and have the Endless Summer Variety. I have the Espoma for lowering PH. Is now too early?

What is a good way to frost protect my old growth buds if we start moving into a warm spring w/occasional frosts? I lost most of my old growth buds to frost last year.

Behind the hydrangeas (4 plants ~5 yrs old ranging 2.5 - 3.5 feet last summer) I plan on planting blueberries. How far away from the Hydrangeas should they be?

By Almanac Staff on March 24

It sounds like powdery mildew. Improve the air circulation and put the plant in a less humid location. You can spray the leaves with a solution of 2 drops of dish soap, 1/2 tablespoon of baking soda and 1/2 gallon of water. Or you can mix 1 1/2 tablespoons of apple cider vinegar in 1/2 gallon of water and use it in a spray bottle.

I bought a container of what

By Laynis on March 23

I bought a container of what I think is macrophilia blue hydrangea las year at my local Costco. I leave in Miami, which is zone 10, but last year my hydrangea did great. It had beautiful blooms that eventually turned green of old and finally I cut them because they were turning brown. This year the plant has a lot of new leaves, but so far no indication of flowers. Also, after I watered them with "miracle grow" a few days ago the leaves lost some of ots luster and the bigger ones are now sometimes floppy. I water it every day and it is in a spot that receives sun part of the day and some shade too. Can I expect flowers this year? What is the best way to care for my hydrangeas? I'm thinking about re-doing my garden and would like to plant hydrangeas but I'm not sure if they will do well. Any advise would be greatly appreciated as I'm new to gardening. Thanks!

By jennifer H

I cut all of the dead stems off of my hydrangea and dead puffs, will they bloom this spring? They are starting to get new buds in the tips and green leafs at the base of the shrub. Late year they turned every color from pink to blue is this normal for them to change colors as the months go by?

Hi Jennifer, If you are

By Almanac Staff

Hi Jennifer,
If you are seeing new growth already your hydrangeas will be blooming in no time. It's the chemistry of the soil that determines the bloom color. In alkaline soil the blooms will be pinker and when grown in acidic soil, the color is bluer. You may have added fertilizer that changed the soils pH or heavy rains could change the chemistry.

Hydrangeas prefer full sun in the morning, with some afternoon shade. Impatients usually grow best in shade. Just make sure that your hydrangea gets enough sun.

My husband gave me a beautiful hydrangea plant for Valentine's day and it is larger than your typical "gift hydrangea" that has been mentioned in previous posts. It had two fully bloomed "heads" and two new ""heads growing but I noticed recently that the stems were turning brown and limp. One of the new ones even broke off. I have tried to keep it close to a window where it can get light and have been watering it about a cup of water every two or three days.

We live in a condominium complex and I am not sure when/if we will be able to put it into the ground. We live in Nashville and have also experienced this horrific winter. Any advice to keep this beautiful plant alive would be helpful!

The hydrangea needs bright sunlight and even moist soil. Don't let the soil dry out but don't overwater. Too warm indoor temperatures may also cause stress to the plant.

Assuming the hydrangea is dormant, keep it that way it in a cool, dark place that will remain between 40 and 50 degrees. You only want to water it before it goes dormant and then leave it alone until early spring, when you will take the plant back outside as soon as the weather warms. Water them well right away, and until we get rain.

Hello Almanac Staff
I live in Edmonton, AB Canada, (zone 3) and garden on a southern exposure balcony with a shady corner. I would love to grow a hydrangea but I have not been successful at over-wintering anything other than a Clematis, which I bring. Which variety will thrive here in a container?

Hydrangea paniculata, also

By Almanac Staff

Hydrangea paniculata, also called PeeGee hydrangea, is hardy to zone 3. There is a ‘compact’ variety available with smaller foliage and flowers. Hydrangea Annabelle is also a Zone 3 hardy variety. If you keep the plant on your balcony you need to protect it somehow during the winter months. Wrap a large blanket around the pot or place the pot in a box filled with newspaper or other insulating materials.

By Almanac Staff

Work organic matter into the soil periodically; garden compost is what we use. However, bone meal is a great source of phosphorus which helps establish good roots; sprinkle around the shrubs after the snow is gone; follow the directions and don't overdo it or you could harm the plant. We wouldn't use blood meal (which adds nitrogen) unless the leaves are yellowing; nitrogen keeps those leaves green.

By SassyMolassy

Hi. I tried finding a comment that was the same as my situation, but could not. I apologize if I missed it.

I received a beautiful hydrangea plant today, January 17 for the passing of my grandmother. I don't have any florist information so I do not know the variety. The plant has large shiny heart-shaped leaves with sawtooth edges. From what I understand, the flower structure is mophead. The larger flowers have blueish/lavender/periwinkle on the outer portion, with pale green centers. The smaller flowers are pale green only. I live in hardiness zone 7b. I would like to keep this plant and put it in one of my beds. Would I be able to do this? How would I go about this since it is currently January? I appreciate any insight and tips. Thank you!

Many hydrangeas grow well in

By Almanac Staff

Many hydrangeas grow well in pots and you can keep your plant healthy buy watering and maybe repotting in a bigger pot. If you keep the plant indoors during the winter months and then plant it outside in the spring it will not have had a dormant (cold) period and will probably not bloom next summer.

I purchased a beautiful

By redline metro

I purchased a beautiful potted hydrangea this spring- the label said it was a "Saxon" hydrangea. I have looked all over the internet, and have had a hard time getting information about it, and most of the information I have found is from Europe. What little I have learned is that it may be a dwarf form of hydrangea, and that it may be able to take more sun, and something about blooming a bit later to protect against frost. Can you verify any of this for me? I want to plant it soon, but am not sure exactly where.
My other issue with this poor plant is that in spite of growing beautifully this spring, I came out one morning to find it completely stripped of leaves and half its height. Unfortunately, we have discovered with a motion activated camera, that deer browse our yard quite frequently to snack. This plant grew back nicely, only to be stripped again. I put a tomato cage over it, and covered it with plastic fencing. It has since grown back some foliage, but not much... Does this poor baby have a prayer?

If the hydrangeas are hardy

By Almanac Staff

If the hydrangeas are hardy to your zone, they'll probably be fine.  They will eventually produce new growth from dormant buds. Keep them mulched with 3 to 4 inches of mulch up to the drip line and maintain the soil evenly moist. Do not add fertilizer while the plant recovers. Do not cut anything back until you see new growth.

Hi Pat,
Your hydrangea will come back next year but may not flower depending on the variety you have. You may have cut off the new flower buds for next year. See pruning advice on this page. To see your hardiness zone go to http://www.plantmaps.com/interactive-ontario-plant-zone-hardiness-map.php

By Almanac Staff

If your hydrangea blooms on old wood you may have cut off the buds when pruning in the spring. Don't prune this spring. Wait and see if you'll have some flowers. Then prune after the flowers fade. Add some compost to the soil around the bush to give it some extra energy.

I have a HUGE hydrangea that needs to be divided. I see that fall is the best time to move them, but is it also the best time to divide them? It also needs to be cut back before & I understand that I may not get blooms next year if I do so, so is this a good time to do this while dividing & transplanting?

You can transplant or move

By Almanac Staff

You can transplant or move hydrangeas anytime that the plant has gone dormant--so fall or early spring before new growth has emerged. All the leaves should be off before attempting to move your plants. If you are doing all this work with dividing, perhaps early spring is better as you have less risk of winter damage.

I have three hydrangeas that

By Natejte

I have three hydrangeas that I planted in the spring...and they have struggles the entire summer season. They have brown edges and the leaves are the color of mint spearmint gum. What am I doing wrong? They did not bloom at all. Thanks

In terms of brown edges, you

By Almanac Staff

In terms of brown edges, you might want to check your hydrangeas for spider mites. Look under the leaves for tiny specks that move and treat with insecticidal soap. In terms of best growth, consult this page. They like moist soil that also drains well. They do not like dry conditions; it's best to amend your soil with organic compost and also mulch to keep the soil cool. Be sure to mulch and protect them if you live in a cold-weather place for winter.
In terms of blooming: lack of flowering is often due to pruning at the wrong time or over-feeding with fertiliser too high in nitrogen or a late spring freeze.

I planted two hydrangeas 3

By Helen Shaw

I planted two hydrangeas 3 weeks ago from my local nursery, they were over crowded in the pots and some leaves were spotty, they each had two blooms. I dug the holes and added compost, set the plants in, leaving the top of the dirt slightly above the ground level as instructed. The leaves are shriveling and I am pulling them off, there are signs of new growth, but some of the new growth is shriveling as well. I am watering them every two days, they get morning shade and some morning sun, with more afternoon sun, but are planted on the left of a japanese maple, so are getting shaded from the strongest afternoon sun. Why are they continuing to lose their leaves?

Hi. I purchased a hydrangea

By Liezl

Hi. I purchased a hydrangea last May during a trade fair. It was in a pot and was in full bloom. The color of the flower is white/yellowish. I transplanted it immediately when I get home. I noticed some of the flowers started to wilt until nothing is left. But fior the first two months,it started to have some growth so I was glad and thought it will live. It's located under a tree but has full sun when it's a sunny day. But since august, it's been raining almost everyday and then the leaves started to turn yellow. What should I do? We have clay soil.I don't want it to die.. It's too beautiful when I bought it.

The rain may be the culprit.

By Almanac Staff

The rain may be the culprit. Hydrangeas do not like to be overwatered. You should amend your soil with coarse sand, compost, and peat moss.

I have two hydrangeas in two different areas of my yard. This is my second season with them and I'm disappointed they haven't bloomed. We thought they were in the perfect home. They have 6 full hours of direct morning sun and are in full shade from about 2pm on. We want to change the soil but I don't want to remove the plant, change the soil and re-plant because I don't want to shock them. Can we change the soil all around it or is it best to remove it, root and all and then re-plant it?

By Almanac Staff

Best time to divide is when the bush is dormant in late fall or early spring. Carefully dig up the plant trying to get the entire rootball. Find a good spot in the middle of the root ball to cut into. Use a spade and/or a pitch fork to cut into the roots and carefully seperate the two sections. Plant and water.

By Almanac Staff

You did everything right. It's OK to prune if there are some brown petals. As you said this was a "gift" hydrangea, our suspicious is simply that this type is different than the nursery container. The foil wrapped hydrangea has usually been grown for a one-time, spectacular show. It's fed just for a big bloom and no thought has been given to its long-term health. It is often grown in a greenhouse and just not hearty enough for the "wild."

Hydrangeas are really meant

By Almanac Staff

Hydrangeas are really meant for cooler climates than Arizona. That said, some readers have tried to grow them. H.quercifolia can tolerate heat. H. macrophylla is adaptable. You will need rich, porous soil (not clay) and may need to add acid to the soil, too. We're not sure it's all worth the effort, but let us know how it goes! There are some gorgeous flowering bushes in Arizona (Bougainvillea is a favorite) and we always advise a more native plant.

By Patti Seugling

I moved about a year ago, and inherited tons of hydrangeas. I prune away the dead stems to the first sign of life on them, and cut out any completely dead ones. My hydrangeas bloom fully, and without problem. However, once they have bloomed, I'm not sure what to do with them. Should I cut off blooms to make way for new growth? Should I cut them as they start to wilt? If I leave them be, as I did last year, they turn colors and right now they are more of the antique hydrangea color of white/pink/green blooms... is this a good thing/normal or are they dead blooms that I should be cutting off? Confused. (they are the droopy kind, not the ones that are compact and stay in a neat little ball)

It is important to understand

By Almanac Staff

It is important to understand which type of hydrangea you own. There are many varieties and they have different plant care guidelines. Take a sample to a nearby nursery.
Based on your description, you probably do NOT have Hydrangea macrophylla which are the bulby type.
The most common type is Hydrangea paniculata 'Grandiflora' -- Pee Gee Hydrangea; you can remove the dead flowers if they bother you, but it is not necessary, For pruning: Thin and/or cut back the previous season's growth in early spring before growth; flower clusters occur on newly developing branches. You do want to prune annual so that you don't get an overgrown hydrangea.

Thanks

Our first guess is that you

By Almanac Staff

Our first guess is that you are overwatering. On doing further reasearch, it seems a strong possibility: One source suggests that this plant tolerates full sun when/if the soil is consistently moist. It sounds like, with your making sure to water every evening, in a setting that has morning sun (which is not the hottest sun of the day), followed by shade, your plant is just too wet. Leave it go for a while—say, until the soil dries out. And then water only occasionally. As for deadheading, this plant benefits from deadheading. That is, it wil continue to produce blooms (until the first frost). We hope this helps.

MY HYDRANGEA LEAVES ON TWO SMALL BUSHES ARE LIGHT GREEN, ALMOST YELLOW. WHAT IS WRONG WITH THEM?

First, monitor the moisture

By El Brant

First, monitor the moisture level and try to make sure that the plants are not being 'over watered'. The other possible culprit is soil ph levels. Take a sample of your soil near the plant to the local arboretum (county extension office). They may offer soil testing - which will tell you what you need to do to correct the soil ph. Either way, this is going to be a relatively easy fix.

I got a plant for Mothers Day, since then it's lost almost all of its leaves and all the blooms died. It was poted in a larger pot in good soil and watered 2-3 times per week. Why is it in so much distress? I do see new growth on it now, but not sure what else to do for it. Can you help?

Florist hydrangeas (the kind

By La

Florist hydrangeas (the kind they sell for mother's day) are much more delicate than shrubs you would buy at a garden center. They are really bred for short-term beauty and most people throw them out when they wilt. If you water it well (not soggy, but don't let it dry out) and keep it in a partly sunny spot (not too hot, protect from full afternoon sun) you might be able to keep it alive and next year get more flowers. Eventually you should plant it in the ground.

Too much shade reduces blooms. You may need to transplant your hydrangea to a sunnier spot. Morning sun is best. Add compost to the soil and add mulch around the plant to keep the soil moist.

Hydrangea flower buds and

By Almanac Staff

Hydrangea flower buds and blossoms turn brown if the plant becomes stressed. It can be caused by not enough water or too much sun. If the buds are exposed to full sun for many hours, the plant cannot provide enough moisture to the buds and they dry out. About 4 hours of morning sun is perfect.

By Melissa Dempsey

I have (2) endless summer hydrangeas, which were just planted March 2013. I live in zone 8. Both are nearing the end of their first flowering. Should I deadhead these? I've read mixed things about deadheading the first growing season.

Also, I have a Nantucket Blue hydrangea, planted the same time as the endless summers. Do I deadhead this one as well? Some of the leaves are brown; should I cut these off? What could be the cause of this?

Thank you!

Do deadhead the spent

By Almanac Staff

Do deadhead the spent flowers. It will encourage new blooms. Don't prune the stems or branches this year. Let the plants get bigger and more established first.
Brown leaves is a sign that the plant isn't getting enough water. Hydrangeas need lots of water. Add some mulch around your plants to keep the moisture in the soil. It's OK to remove the brown leaves.

Many hydrangeas will grow well in pots. Choose a pot that is about 2 to 4 inches bigger than the pot the plant came in. Follow the planting advice above and put the container in a sunny or semi-sunny spot on your balcony. Depending on where you live you need to protect it with mulch or other coverings over the winter months.

First, you need to know what

By Almanac Staff

First, you need to know what type of hydrangea you have. For mophead, lacecaps, and oaklead varieties, the best time to prune is actually in the summer before August. They form their buds on "old wood" in Aug/Sept/Fall for the following season's bloom. If it's cut back in June or July, it won't harm the next year's bloom.
However, PeeGee hydrangeas can be pruned any time except for the spring/summer when they are preparing to bloom. You can prune them in the fall, winter, or spring. If you prune at the wrong time, you may harm the next season's blooms but it's not forever!

Hydrangeas grow well in pots.

By Almanac Staff

Hydrangeas grow well in pots. The main disadvantage is the difficulty of keeping them watered. Plant a larger size plant (if you bought the plant in a 3 or 5 gallon container) in a large container. Smaller hydrangeas should be started in smaller pots and then moved into bigger pots after 1 or 2 years.

By Almanac Staff

Plant hydrangea outside after the danger of frost is long past. Use a soil mix rich in sphagnum peat moss. To maintain acidity, fertilize once a month with aluminum sulfate. Only remove the blooms when they turn brown. If your flowers are droopy, you can use a peony hoop or stake them with cloth straps. What is your variety of hydrangea? Be sure to prune properly so that you do not mistakenly remove next year's buds! See this page on varieties.

Often hydrangea plants that come with foil around the pot are are one-time bloom. However, if yours has a tag indicating hardiness zone, then that suggests it's from a nursery. It is always best to plant the potted hydrangea outdoors whenever possible. Hydrangea plants need winter dormancy to "chill" if they are to bloom. Unfortunately, you did not receive a variety meant for your gardening zone. You can try it out; early or late freezes may damage flower buds and you may have less blooms. Plant in early to mid summer so it has time to acclimate before winter arrives.

Potted hydrangea need large

By Almanac Staff

Potted hydrangea need large quantities of water and should never dry out. Check the soil several times a day. Do not allow the pot to sit in a pan of water for long though. If the plant still wilts severely, submerge both the pot and soil in a pan of deep water and allow it to sit there until the soil ball is thoroughly soaked. Drain. Also, make sure your hydrangea gets a lot of sun. Place it in a sunny window but not so direct that the blooms will burn. Hydrangeas like cool temps. At nighttime, keep in a room that is 50 to 60 degrees F.

I'm so glad I found your site! We moved into a home last Nov. that has three hydrangeas. Two of them are large, one much smaller. They all three bloomed beautifully in early spring. After the blooms died, I waited a while, then dead-headed them after reading a post on-line. I noticed a lot of dark spots on the stems, then the leaves began to turn brown on the tips, It has been unbearably hot, but I have been watering them most mornings. It will appear they are trying to bloom again, but the buds just die away. Part of the two bigger ones look ok, but have the dark, crispy tips. What can I do to save them? They were beautiful, and I"m afraid I killed them somehow. Oh, Plus, I've noticed an ant hill right beside the middle one. If I get bitten by one when watering, it turns into a small cyst-like bump.

By Almanac Staff

Unlike pruning, just removing dead blooms (called deadheading) can be done at any time without harming the blooms for the following year. You can remove old blooms down to the closest set of leaves. This can prolong a bloom season. However, it's not necessary to remove old blooms. Some folks think leaving the old blooms on the plant for the winter protects the buds and deadhead in early spring when the shrub begins to leaf out.

As far as testing your soil's pH, you can send samples in to a soil lab testing site or pick up an at home pH kit from your local gardening center.

Change the color?

By Anonymous

Is there a way to make the white Annabelles stay white longer? If not, can they be changed to pink or blue?

Hydrangea color

By Almanac Staff

The flower color of these plants varies depending on the pH level of the soil that they live in. For example, pink flowers enjoy neutral soils while blue flowers tend to enjoy soil with a higher acidic level. Whites tend to fall into the same category as pink.

Start by testing the pH level of the soil to learn whether or not you need to increase or decrease the amount of acid to treat your soil in order to achieve the color you desire.

I hope this helps!

My friend has one plant that is 6ft wide by 4 1/2 tall. This plant has purple,pink,& blue blooms.
Can we split it, sort of like you can do with hostas?

Yes, with care. Divide in the early spring by using a shovel to divide the clump. You're going to need to water, water, water all season to help it restart growth.

Espoma Soil Acidifier

By Anonymous

Ok, so I bought some Espoma Soil Acidifier for my soil that tested at 8.0 alkaline pH but now i don't know how much to put per plant. I have two hydrangea's and a lot of roses. the instructions are below:

Soil Acidifier Recommendation
In the absence of a soil test, follow the rates below. Results can take up to several weeks depending on rate, soil temperature and timing of application. Reduce the rates by one-third for sandy soils and increase by one-half for clay soils. In general, the optimum range for blue hydrangeas is 5.5 - 6.0, and for blueberries it's 4.5 - 5.0.
Pounds per 100 Square Feet of Loamy Soil
Desired pH:
Present pH 6.5 6.0 5.5 5.0 4.5
8.0 3 4 5 6 7
7.5 2 3 4 5 6
7.0 1 2 3 4 5
6.5 NA 1 2 3 4
6.0 NA NA 1 2 3

Any help would be welcomed!
Thanks

Me again...

Sorry, just me again. I haven't opened this Espoma Acidifier yet. It is 18% free sulfur and 12% combined sulfur. I have two small hydrangea's that I just planted and about 13 rose plants. I have no idea how much of this stuff to use. It says on it to use 1 1/4 cup on hydrangea's? Seriously? And it doesn't specify all at once or multiple treatments. Also it doesn't specify for roses! Broadcast rates: 12lbs per 100 sq ft for each 1 point reduction pH required. My soil is at 8.0. That would be a heck of alot! I am not sure if I should take it back and find something else that would do better or just use this and how much to use? I just now that my plants really need the help. Just using some coffee grounds right now.

Anyway, thanks for any help!

By Almanac Staff

We suggest that you use 1 to 1-1/4 cups of Espoma around each plant. Spread evenly around the plant out to the drip line and water well. Repeat in 60 day intervals until desired pH or bloom color is achieved.

When is the best time to

By bluejeanbaby on March 23

When is the best time to begin fertilizing Hydrangea plants in the spring to encourage blue flowers? I have the Espoma fertilizer. My plants are several years old (~5) and range from 2.5 to 3.5 feet high. I live in Zone 5.

Also, what is the best way to protect them from a late spring frost. I only got a few blooms last year. Admittedly, I was not good about fertilizing them, but I think our sometimes late spring freezes were the major culprit.

Alkaline soil...

By Anonymous

I am so grateful for this site!

I live in Indiana and just bought 2 hydrangea's. A Forever and Ever blue heaven and a forever and ever peppermint hydrangea. I planted one next to the house where it gets about 7 hours of sun and then shade in the afternoon. Anyway, I had tested the soil with a store soil test kit and according to the color it turned dark green which means alkaline (I tested it with a gallon of water that said spring water). Then I tested it 3 ft away but used the bottled water I drink and it was a lighter green which means 7.0 to 8.0. I have well water that comes out of my faucets and didn't use that. Should I try again with my well water to see exactly how much pH?

I read that compost can help and grass clippings and peat moss and coffee grounds. I don't know since I just planted it if I should use sulphur or sulphate or just coffee grounds and peat moss?

Thanks for the help. (I also have about 20 rose bushes and the plants are doing ok it seems, but I still need to lower the hP for them also...)

When you test your soil, you should NOT use bottled spring water, bottled drinking water, or well water. All may have high levels of dissolved minerals that can skew your test. Invest in a gallon of distilled or reverse osmosis purified water, and use only that water for your pH testing.

I wrote that comment. One more thing... I don't think I have that good of drainage. I planted the hydrangea so it is slightly higher than the ground around, kind of like a small hill and put some tiny pebbles in the soil when I planted it. I also tried to pack some of the soil down so to not have any air pockets. Is there anything I should change for the next hydrangea?

Thanks again.

To lower the pH quickly add

By Almanac Staff

To lower the pH quickly add sphagnum peat. It is also a good source of organic matter and helps drainage. (The pH of Canadian sphagnum peat generally ranges from 3.0 to 4.5.) Add a 1 to 2-inch layer of sphagnum peat and work it into the top 8 to 12 inches of soil before planting (work as much peat into the soil around your established hydrangeas as you can). Keep adding your coffee grounds too. Soil with pH level of about 5.2-5.5 will produce blue flowers, soil with pH level above 6.0 will produce pink flowers.
The hydrangeas need an evenly moist well-drained soil for best growth and benefit from being planted in a relatively sheltered location with morning sun and afternoon shade. Apply organic mulch around the plants to conserve soil moisture and protect them from temperature extremes. All the best!
