Hydrangeas can sometimes be a tricky plant to care for, so it is important to learn when to prune different hydrangea varieties and how to prune hydrangeas. Properly pruning hydrangeas based on your hydrangea’s variety will allow you to have more blooms next year.

Before you start pruning hydrangeas, it’s important to figure out which variety you have. If you prune at the wrong time, you could be cutting off next year’s blooms.

Pruning Hydrangea Varieties

Bigleaf Hydrangeas (Hydrangea macrophylla)

Even though my area is hardy to Zone 5, my ‘Endless Summer’ mophead hydrangea—which usually has huge blue blossoms all summer long—was killed to the ground. Luckily, it has the wonderful ability to bloom on both old and new woodso even though they were a bit later than usual, there were still many blooms.

‘Endless Summer’ in a good year.

My other blue hydrangea is a lacecap-type, called ‘Let’s Dance Starlight’, but instead of the huge, mophead-type of flower cluster that ‘Endless Summer’ has, the lacecap hydrangea bears a flat blossom made up of many small, fertile flowers surrounded by a few showy, sterile flowers. It is also hardy to Zone 5 and blooms on both old and new wood.

Lacecap ‘Let’s Dance Starlight’

Both mophead and lacecap hydrangeas are considered bigleaf or macrophylla hydrangeas, so they can be pruned right after flowering by cutting back the flowering shoots to the next bud. If you have older plants that aren’t blooming well, you can cut up to a third of the stems off at the base in late summer to encourage new growth.

Panicle Hydrangeas (H. paniculata)

The hydrangeas grown most often in New England gardens are the panicle-types, since they are not only beautiful, but also very hardy, surviving Zone 3 winters with no problems. One of the oldest and most reliable favorites is ‘Grandiflora’, also known as Pee Gee hydrangea. Native to China and Japan, it was the first Asian hydrangea cultivar introduced to the United States, in 1862. They were a big hit during the Victorian era. The flowers start out a creamy white and turn a rosy pink as they age. They can be dried and look lovely in a winter arrangement. Find out how to dry these lovely hydrangeas here.

There are many panicle-types to choose from. I have one called ‘Pinky Winky’ that has long, cone-shaped white and pink flowers, and also ‘Vanilla Strawberry’, which has panicles that color from white at the tip to pink in the middle and red at the base. For something different, try ‘Limelight,’ which has chartreuse flowers that gradually turn pink in autumn.

Panicle-type hydrangeas should be pruned in late winter to keep them from becoming overgrown.

Panicle-type hydrangea ‘Vanilla Strawberry’

Smooth Hydrangeas (H. arborescens)

Smooth hydrangeas are North American natives, originally found growing wild in Pennsylvania. They tolerate light shade, begin to bloom in June, and continue to blossom until fall. Their white flowers are round and can reach 12 inches in diameter.

Smooth hydrangea ‘Annabelle’

The popular cultivar ‘Annabelle’ grows to be 3-5 feet tall and can be used to light up a shady path or as a mass planting at the edge of the woods. It is hardy to Zone 3.

Smooth hydrangeas can be pruned back to the ground in the fall or early spring.

Oakleaf Hydrangeas (H. quercifolia)

Oak-leaf hydrangeas are another North American native, having been discovered in Georgia in 1773.

Oak-leaf hydrangea

Also called swamp snowball, it is hardy to zone 5 and though it prefers full sun, it can take some shade and still blossom well. It blooms a little later than the other hydrangeas, beginning in August. Its flowers are large panicles that start out white and turn dark pink as they age. The leaves, which are deeply lobed like an oak leaf, turn a rich maroon red in the fall.

Oak-leaf hydrangeas don’t need a lot of pruning, but if you want to tidy yours up, prune out the dead stems at the base in early spring.

Is there a chart of different varieties that show when to prune, growth on old or new wood, when to fertilize and with what. I find myself reading pages and pages, and depending on who writes the article differ. I'm not new to hydrangeas and have macrophylla, panicle, oak leaf, Bits of Lace, Lacecaps, but its getting hard to keep them all straight. I too had plants that haven't bloomed now for 2 yrs, need to make sure they get the right nutrition. Also I have read where some put coffee grounds on hydrangeas, true or false if so how much and often. is there anything I can do this year to help next yrs blooms?

I have not found a chart but

I have not found a chart but to distill it down, don’t prune until after your hydrangea has bloomed, if you must prune it at all. Fertilize in the spring by scratching in some slow release fertilizer, well-rotted manure or compost around the base of the plant (not touching the trunk). Coffee grounds are slightly acidic and many gardeners claim that they will change the soil pH enough to change the color of a mophead from pink to blue. As far as helping next year’s blooms, if your plant has not been blooming stop pruning it, make sure it gets at least 4 hours of sun a day, gets sufficient water throughout the season, and if frost is damaging your buds give the plant some winter protection.

Hi Brenda, I just found a

Hi Brenda, I just found a good source of info on pruning hydrangeas at the University of Maryland Extension. Here is the link https://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/ornamentals/HG106_Pruning_hydrangea_2018.pdf. I hope you find it helpful!

Hydrangeas & Peonies

I moved from Vancouver Island to Bowling Green KY, both USDA Zone 6B, but oh my what a different climate here; so hot and muggy in summer. My macrophylla hydrangeas suffered die-back last winter and while growing well now, havent bloomed since I got them. They dont seem to like full sun, cowering . Is it too hot? ALso noticed flowers open and fall off peonies far more quickly here in the heat. I am finding it quite an adjustment to go from where things grow so easily to trying to sort out what will thrive and what won't.

Going from Vancouver to

Going from Vancouver to Kentucky is a huge change! Most macrophylla hydrangeas bloom on last year’s wood so if yours died back to the ground this spring you won’t have any flowers this year. Let this years’ growth stay on the plants (don’t prune them) and if it overwinters, you should have flowers next year. The hot summers do take a toll on these plants so plant them where they get morning sun and afternoon shade and be sure they get plenty of water. Instead of a macro, try an oakleaf hydrangea, which is native to the southeast. If a full sun area is all you have to work with try a paniculata type.  Hot summer sun will also blast your peony flowers. Early season varieties are recommended for the south. They will bloom before hot weather arrives and shortens the life of the blossoms.

Non blooming hydrangea

I have the same problem as Linda in Ohio.I have tried cutting them all the way back to base, this year I didn't cut back at all ( someone told me I needed to let old wood there because they would bloom on the old wood).I have 2. blooms on one plant is all. What should I do now (help ) ?

Hi Gary, Look at my answers

Hi Gary, Look at my answers to Linda and they may help you as well. Find out what variety you are growing and go from there. If you got a few blossoms this year on old wood then I would guess that you have a macrophylla too. Continue to not prune at all. If there is a lot of dead wood in the spring you can take that out but not all the way to the ground. Check the amount of sunlight the plants get and don’t over-fertilize. You might consider giving the plants some winter protection like a wire cage full of leaves.


The first year I planted mine I had big blooms. Now some 3 years later I have NONE. I did not prune to the ground but just left them as is for the winter. Each successive year the plants come back but with NO blooms!!! I have white and blue. Now this year (year 4) still no blooms. What am I doing wrong?

First it helps to know what

First it helps to know what type of hydrangea you have. I assume since you had some blue flowers it might be a macrophylla.

There are many reasons why hydrangeas don’t bloom. Macrophyllas bloom on old wood so the buds may be getting damaged by late spring freezes or winter winds if the plants are not protected over the winter.  The buds for macrophyllas are formed a whole year ahead of time so there is lots of time for them to be damaged. The variety you have might not be appropriate for your zone. Lack of sunlight could be the culprit; they need at least 4 hours of sun a day. Have your soil tested. If the plants get big and bushy but have no blossoms they may be overfertilized. Too much nitrogen grows a big plant with no blossoms. If you fertilize your lawn to green it up in the spring that fertilizer can wash into the root zone of your hydrangea and give it too much nitrogen. Phosphorus encourages blossoming. A soil test will tell you what you are lacking. Do some research starting with the variety and if it grows well in your zone. Good Luck!

Article in The Old Farmer's Almanac - Hydrangea Care: Pruning Hy

Thank you Robin Sweetser for your article on pruning Hydrangea varieties.
I have a 4 year old Endless Summer and just love it. Your article was informative, straight-forward and easy to understand. Good, simple, to the point info on how to prune the various varieties of Hydrangea is hard to come by. Loved your article.

Looking forward to learning

Looking forward to learning more plants and how to keep them alive and well.

When can I transplant a hydrangea?


Best time to transplant hydrangea when the plant is dormant ( late Fall to early Spring )

Hydrangea shoots

My hydrangea plants that have bloomed beautifully this year are now hidden by huge shoots. Can these be removed or do next year's bloom come from them?

Cut stemmy shoots or not?

I am not sure what is proper pruning of these that will encourage flowering each year. These are 20 year old plants....


Hiw and when do you prune the Endless Summer hydrangea? I didn't see it in the article. Maybe I missed it.

Should I cut Endless Summer back to about 15" each spring

I have several Endless Summers & 2 huge big leaf Mopheads. Should I cut them back in spring to about 15-20" high, or will I get no blooms if I do that ?

Cutting Hydrangea blossooms for bouquets

My hydrangeas are gorgeous! If I cut some for bouquets, will they bloom again this season? I know that is a trait for annuals but thought I'd ask. I love looking at the plant and love indoor bouquets.

Dead Heads

Can I cut off the dead flowers or am I better off letting them fall off? My beautiful blue mophead is looking horrid. We planted the bush in early May, and it bloomed so pretty. I cut a few of the lower flowers off because I could not help myself. Did I hurt it? We do have a few new blooms growing in but can't see them well through all the deadheads.

Hydrangeas pruning

I have a very hardy mophead hydrangea planted many years ago by my mother. My problem is that all of the stalks seem to die off every winter, so I've been pruning them back to the ground each spring. It becomes a big beautiful bush again every year, but doesn't bloom. What am I doing wrong, and what can I do to keep it from dying off every winter? I live in southern New York state, have never fertilized them, but sure do miss the blossoms!

Hi Craig,

Hi Craig,

You have removed the new buds with your spring pruning. Mophead hydrangeas bloom on old wood and produce flower buds on the stems in late summer for the following summer’s blooms. If those stems are pruned in the fall, winter, or spring, the buds will be removed, and there may be no blooms the following summer. Cut the bush back about ⅓ in July and hope for blooms next year.

Caring/pruning Blue Hydrangea

I live in S.Fla and growing my Blue ( PINK) Hydrangea in a container outside in east morning sun. It requires deep watering every other day or the six med. size balls of flowers droop. I feed it MiracleGro twice a month as directed. Am I doing right by my plant??? When is a good time to Prune and how is it done? When I purchased my plant, it was just a dried stick of wood and in a few weeks, it turned into a beauty...

It sounds like you are taking

It sounds like you are taking good care of your potted hydrangea. Watering is critical for any container plant  but especially for water-loving hydrangeas. After it has finished blooming you could cut it back and repot in a larger container with fresh soil.

Hi should i prune my plant now or wait for spring.

Very few blossoms last year a lot of rain in Oklahoma in the Spring.

Hi Norman, If you are unsure

Hi Norman, If you are unsure what type of hydrangea you have it is best to wait until after it flowers to prune it. Some plants bloom on old wood and you would be cutting off next year’s blossoms if you prune it now. Usually a plant that blooms before June 15th blooms on old wood and those that flower later in the season flower on new wood. Some varieties - like ‘Endless Summer’ - bloom on new and old wood. Other than removing dead wood, I would wait until after it flowers to do any serious pruning.

I just received a beautiful

I just received a beautiful Endless Summer hydrangea. What type of fertilizer should I use & when should I use it? Also, I was told it needed at least 5 hours of sunlight. Is this correct? Thank you so much!!

Most hydrangeas benefit from

Most hydrangeas benefit from an application of fertilizer in the spring and one again in the fall. The Endless Summer website recommends using a slow-release granular 10-30-10 fertilizer. Follow the directions on the package for the amount to use. Overfertilizing will cause your plant to grow large lush leaves but stunts blossoming.
Five hours of sun sounds right. Full morning sun and dappled afternoon shade is recommended.

Thank you so much for your

Thank you so much for your quick reply! I sure do appreciate it and the information provided.

I usually wait until Spring

I usually wait until Spring when my hydrangeas begin to leaf out and after a couple of weeks, the dead branches are obvious and I cut them off at that time. I have never failed to have blooms until this year and I failed to cut back the dead wood and don't know if it made any difference, but I never had one bloom on that plant. Have others that I did trim back and had blooms in profusion on those. Anyway, I love my hydrangeas. P.S. mine are all mop heads.

I have a Bridal Veil

I have a Bridal Veil hydrangea. When is the correct time to prune this variety? At this point it seems to die back almost to the ground in hard winters and I have been cutting back the dead parts. There are lots of blooms late summer on this plant now and just a few during the early summer. Is this the correct way to prune this?


Bridal Veil is a Pee Gee type

Bridal Veil is a Pee Gee type of hydrangea which blooms on the current year's growth so pruning it in late winter/early spring is perfect!

I have some Endless Summer

I have some Endless Summer and some Lady in Red (lacecap) hydrangeas. I planted them two years ago, and they have been blooming and growing well. My problem is I planted them too close together, and they're too crowded. When can I move a couple of them to new homes?

The best time to move your

The best time to move your hydrangeas is in late fall or early spring when the plants are dormant.

I have two Smooth hydrangeas,

I have two Smooth hydrangeas, white with dozens of big beautiful blooms. These plants are at least thirty years old. Unfortunately, after it rains, the stems and blooms fall to the ground due to the weight of the water. I try and shake off the excessive water but usually they stay down. I have tried to use rope, individual stem supports and peony rings to support the stems but that looks awful! Would you have any suggestions, please? Thanks.

I've tried all manner of

I've tried all manner of supports too - tomato cages, wire fencing, peony rings and stakes of all sorts. There is no pretty way to support them. Green bamboo or green wire supports tend to disapper better in the foliage than other devices. I try to place peony rings that have wire criss-crossing on top early in the season and let the plants grow up through the wire. It supports the stems pretty well and is hard to see. My personal solution is to cut a lot of the bigger flowerheads for bouquets or to dry for winter arrangements.

I have oak leaf hydrangea.

I have oak leaf hydrangea. They grow very fast and have to trim them down to see out the window.
When is the best time and how far down should I prune.

Prune your oakleaf hydrangea

Prune your oakleaf hydrangea right after it flowers. It blooms on old wood so you don't want to take out too many branches or you will sacrifice next season's flowers. They can grow to be quite tall so if it causes a problem every year you might consider moving it to another location.

I do not know what kind my

I do not know what kind my hydrangea mine is but,it looks like a mophead. I was told by my neighbor that his Father-in-law told him to put a piece of copperwire in the ground next to the main stem to help it to grow and bloom. It has the prettiest blue, purple and pink flowers. I also fertilize it with my leftover coffee and grounds. I dilute it so that it does not burn it.
I Hope this helps. My hydrangea is 3 yrs. old given to me for Mother's Day by one of my adult sons.

Often a plant that is has

Often a plant that is has lush growth but no flowers has been fed too much high nitrogen fertilizer. It could even be leaching from your lawn if you fertilize that. Check the location. Is it getting enough sun? Lastly, it might just be the wrong variety for your area.

i have an Endless Summer that

i have an Endless Summer that is about 5 years old. I always waited until it started growing in the spring and at that point I cut off the dead wood. It was a beautiful plant with lots of flowers. A few summers ago someone clipped a bunch of flowers and branches. It has never bloomed since. Do you think the middle summer plant thief damaged the plant? And will it ever bloom again?

Plant thieves should be

Plant thieves should be sentenced to hard labor in the gardens they spoil! Your poor plant should have recovered by now. Do you get late spring frosts where you live? Sometimes they damage developing buds. Perhaps it just needs a little bone meal or other fertilizer that's high in phosphorus to encourage it to bloom.

It may be planted in the wrong place. They need morning sun and afternoon shade. The farther north you live the more sun they can handle, but they will not grow well in heavy shade. They need well drained soil and like to be kept evenly moist but not too wet. Your soil my be lacking key nutrients. Have a soil test to see what you need.

I have Endless Summer and I still do not understand from your article when to prune. I just prune the dead stalks. Can you advise?

Sorry I was not clear, Chris.

Sorry I was not clear, Chris. I do the same as you. I just wait until I see what has died over the winter and cut that back to living wood to not lose those early blossoms.

I improperly pruned my

I improperly pruned my hydrangeas two years ago. They still haven't bloomed. I believe they are mop head variety. They had beautiful blue blossoms on one plant and pink on another. Will these hydrangeas ever bloom again? I live in Tennessee.

If they have successfully

If they have successfully bloomed for you in the past they will recover from their bad haircut and bloom for you again.

This is very helpful. I have

This is very helpful. I have mopheads and they did not even bloom this year. Any thoughts?

There are many reasons why hydrangeas don't bloom. Did they die back to the ground this spring? If so they won't bloom again until next year since most mopheads bloom on old wood.
