Deadheading your hydrangea plant in the early spring is the best approach to maintain aesthetics.
Once the bush has blossomed and survived the rigorous winter, this is typically done.
Using only a pair of scissors or secateurs, deadheading your hydrangea is fairly simple.
To uncover the layer of growth that is budding in preparation for the summer, just cut back the stem to the first robust, healthy pair of buds that are just below the faded blooms on top.
Avoid cutting too quickly; these tiny buds represent the beginnings of a new plant development.
These won’t produce the same stunning blooms the following season if you accidently cut them.
When should I prune my hydrangea’s dead heads?
These are your macrophylla hydrangeas, also known as mophead and lacecap, which come in purple, pink, and blue. They also include hydrangeas with oak-shaped leaves. While reblooming kinds flower twice, some cultivars only bloom once per season on stems from the previous year (old wood).
The initial set of hydrangea blossoms should be deadheaded as soon as they start to turn brown and dry. Cut the stem immediately above the first set of leaves and below the flower head. When this second set starts to fade, you can deadhead once again for reblooming varieties, but only until about mid-August. Your hydrangeas will then produce buds for the flowers of the next year; you don’t want to unintentionally cut these off. After the summer has ended, dried flower heads can remain on the shrubs to add visual interest over the winter.
Pruning mophead hydrangeas
Mophead hydrangeas bloom from buds that were created the year before. To avoid chopping off flower buds, they just need deadheading and very little pruning.
Mophead hydrangeas should not be pruned until late spring since the old flowerheads provide some shelter from late frosts for the young buds.
- Cut back to the first pair of robust buds beneath each flowerhead while deadheading any old flowerheads.
- Remove any stems that are crossing, dead, or damaged.
- To encourage the plant to develop new growth, prune one or two old stems down to the ground on older plants.
Pruning lacecap hydrangeas
Lacecap hydrangeas are maintained similarly to mophead hydrangeas and bloom on buds that have developed over the previous year. Mophead hydrangeas need to be clipped in the spring, whereas lacecap hydrangeas can be pruned in the fall.
- Cut back to the second pair of buds beneath each flowerhead while deadheading all old flowerheads.
Pruning Hydrangea paniculata and Hydrangea arborescens
Both of these species need new growth to produce flowers, therefore prune them in the early spring to encourage the emergence of new stems carrying flowers.
- Remove any damaged or crossed branches as well as any dead timber.
- Cut the stems from last year’s plant by roughly a third, just above a pair of robust, healthy buds.
Pruning climbing hydrangeas
Because climbing hydrangeas take a while to take off, pruning is typically unnecessary for the first two to three years following planting. Once they do begin to grow, they can develop into very vivacious plants that can grow as tall as 10 m (32 ft), therefore it’s a good idea to cut them each year to keep them in check.
- To reduce the chance of removing any future flower buds, prune as soon as possible after summer flowering.
- Cut back any exceptionally long, straggling shoots to a pair of lower, strong, healthy buds. Since the majority of the blossoms will grow at the plant’s top, try not to remove too much of it.
A mature climbing hydrangea can be pruned in the spring to make it smaller. Hard trimming won’t harm climbing hydrangeas, but it will probably result in less flowers for a year or two following. To lessen the stress on the plant, if you are drastically shrinking the size of the plant, do so gradually over two or three years.
Other hydrangea varieties, such Hydrangea aspera and the oak-leaved hydrangea (Hydrangea quercifolia), just require a mild spring pruning to maintain size, give the plants a pleasing form, and remove any dead wood.
It’s fairly easy to prune hydrangeas, and the benefits are well worth the work. If you follow our detailed instructions, your borders will be covered in blooms this summer.
Do my UK hydrangeas need to be deadheaded?
To keep your hydrangeas looking their best and promote the development of new flowers, deadhead regularly during the blooming season.
But in mid- to late-fall, stop deadheading hydrangea shrubs, leaving any spent blooms in situ. This not only adds beauty to the winter landscape but also guarantees that the buds that will bloom the following spring are not removed.
Should I remove the hydrangea’s dead blooms?
Because hydrangea blossoms are so large, deadheading a hydrangea can help the plant focus energy on other, more crucial aspects of its growth. To promote new blossoms and keep your plant appearing healthy, you should continue this approach throughout the flowering season. The time of year determines the best way to deadhead hydrangea blossoms.
You should cut the wasted blossoms with a long stem still attached if it’s before August. Look at the stem’s junction with the larger branch; there ought to be several little buds there. Make sure to keep the buds whole when trimming the stem back as short as you wish.
The plant is probably developing new buds along the stems in anticipation of the following spring if it is August or later. Check the area between each set of leaves as you work your way down the stem from the faded bloom. You should see buds at the first or second pair of leaves. Offset the spent bloom far above those buds with a knife.
Carry a cloth that has been dipped in denatured alcohol while you work. To stop disease from spreading throughout the bush, wipe your pruners clean with the rag in between cuts.
What happens to hydrangeas if I don’t deadhead them?
Deadheading too-tall hydrangeas can occasionally be challenging. Your other option is to keep them on if you don’t have the skills to reach spent flowers or all of the spent blooms. And you can do that without suffering too much harm.
Simply omit deadheading hydrangeas, and your plant won’t suffer. At least nothing major enough to need worrying about.
Your hydrangea might not produce as many or as large of blooms as it would have if the spent blooms had been removed. It will nevertheless continue to bloom.
Having said that, you can think about pruning hydrangeas that have gotten too tall in order to make them smaller and easier to handle.
This will make it simpler for you to maintain the tidy appearance of your hydrangeas. Additionally, it will make it simpler to remove spent blooms from plants and promote future blooms with greater vigor.
Do I need to remove Brown hydrangea blossoms in the winter?
Myers advises leaving the dried blossoms on your hydrangeas if you’re looking for an easy way to spice up your winter yard. Bigleaf hydrangeas produce their final rush of flowers in the fall, so to enjoy the dried blossoms all winter long, stop deadheading at that time. To aid in the production of healthy buds in the spring, these can be removed.
When should hydrangeas be pruned?
Depending on which group the plant belongs to, the timing and extent of pruning are determined:
Advice on Pruning for Group 1:
- As the days get shorter and the weather gets colder in the late summer and fall, buds for the following year’s blooms start to form.
- Typically, removing dead, diseased, or damaged branches is all that is required to preserve shape, size, and a healthy plant. Otherwise, gentle pruning ought to be practiced.
- In the summer, trimming should begin as soon as flowering ends, but no later than August 1. Pruning should not be done in the fall, winter, or spring because you risk removing fresh buds.
- Tip-pruning the branches in the spring as the leaves begin to appear can promote more numerous, smaller flower heads as opposed to fewer, larger flower heads.
Advice on Pruning for Group 2:
- On the growth of the current year, flower buds form.
- Early in the spring, as the leaves are starting to emerge, prune.
- Just above a node, prune branches back by half to a third.
- After that, prune any fragile or spindly branches.
- Minimal trimming encourages huge, strong bushes with many of tiny flower heads in H. arborescens. Hard pruning between 12 and 18 inches from the ground, or even all the way down, will result in fewer but larger flower heads that may flop if unsupported.
- For H. paniculata, remove the surrounding smaller wood while leaving the larger stems in order to establish a sturdy foundation.
Pruning may be connected to flower head size. Shoots will grow more vigorously and flower heads will be bigger and fewer with more rigorous trimming. Smaller but more numerous flower heads may result from less aggressive or tip pruning.
Consideration of hydrangeas’ mature size is the best piece of advise. Place them in a location where they won’t outgrow and won’t need a lot of pruning to keep them in check. Hydrangeas don’t need to be pruned precisely or often; as long as dead wood is removed, they will remain healthy and continue to develop and bloom.
What should you do if hydrangea blooms start to deteriorate?
The beauty of hydrangeas is expected to last a lifetime! The garden’s most perfect, essential blossoms! However, you can see dark stains on the leaves of your hydrangea. Or even worse, the blossoms are fading to brown!
If you stay with us, we’ll have your garden favorite looking fantastic once more. Here’s a quick cure for those typical hydrangea issues.
Simple Steps to Stunning Blooms (Again)
How to Address Typical Hydrangea Issues
Not a Spot! Hydrangea leaves get unattractive, black stains when it rains unusually much (or if you overwater them). This Cercospora leaf fungus is relatively innocuous despite its frightening name. Remove badly impacted foliage and leaves with spots to stop the fungus from spreading.
Will to Wilt 2. Are the hydrangea blossoms withering or drooping? Your plant is most likely receiving insufficient water and too much light. Verify that the soil is moist one to two feet down. If not, deeply spritz. Repeat weekly for optimum hydrangea care. Mulch can also help you save water, so add some. If that isn’t the case, perform a soil test to determine the nitrogen levels in your soil. Make the necessary changes.
Three. Brown Blooms Your hydrangea blooms may need extra water if they are prematurely turning brown and fading away. The same applies if your flowers start to wilt during the day and don’t recover at night. Look for brown stains on the leaf edges to confirm. Once a week, deeply water hydrangeas to mend.
4. Holy Grail Foliage. Hydrangea leaves have holes chewed through by fruit bugs and slugs. Open a holey leaf. A fruit worm is what you should locate if it resembles a caterpillar. Utilize soapy water to get rid of them. Slugs are probably responsible if nothing is found. They can be hand-selected at night or given a nightcap. Bury a plastic cup so that the rim is level with the ground next to the hydrangea. Then pour half a beer into the cup.
Blooms Be Gone, No. 5. Your hydrangea is barren of blossoms. You probably pruned your hydrangea at the incorrect time, removing all of its fresh blossoms. Instead of trimming hydrangeas this year, read our hydrangea pruning recommendations to ensure that you never prune them at the incorrect time again.
Purple Pout, 6. Remove the leaves and branches that have the purple stains from your leaves. You may not have enough phosphorus in your soil if the entire leaf is purple. Test your soil, and adjust as necessary.
Abracadabra! Your hydrangea issues will shortly be resolved. Then, you can concentrate on all the wonderful aspects of cultivating hydrangeas, such as enjoying their enormous, fluffy blossoms.
Cut back these shrubs in late winter before new growth begins
Shrubs that flower on young wood typically start blooming later than old-growth bloomers, beginning in June and continuing until the first frost, because they need to grow and set buds the same year that they bloom. As long as you avoid trimming when the flower buds are opening, these shrubs are understanding if it is not done at a specific period.
1. Trim the flowers all the way back for larger blooms.
These bushes can be completely removed from the ground in late winter or the beginning of spring. If cut severely like this every year, smooth hydrangeas will produce much larger flowers, but many gardeners prefer smaller blooms on stronger stems.
2. Maintain an old growth foundation to lessen flopping
Especially after watering from above or after a heavy storm, the branches of some hydrangeas frequently topple over from the weight of their blooms. Cutting the stems to a height of 18 to 24 inches will help to reduce this flopping by creating a strong framework for fresh growth.

Should I remove the spring blooms of my brown hydrangea?
Pruning is not typically thought of as one of the many gardening activities that may be done in the fall, despite the fact that there are several. It can be difficult to cultivate hydrangeas successfully in New Hampshire, and if you want your plants to blossom, there is frequently very little room for error in pruning.
Wait until Spring to prune hydrangeas
In New Hampshire, hydrangeas come in a variety of kinds, and each one has quite distinct growth patterns and pruning needs. Some plants only produce flowers on fresh growth, while others mostly produce flower buds on older wood. In any case, it is better to postpone all hydrangea pruning until spring. Hydrangeas, as with all other trees and shrubs, go dormant in the fall. Not much new growth is produced by them until the next spring. As new growth is more vulnerable to harsh cold at the location of wounds, plants that have been trimmed now run a higher risk of winter damage. Additionally, fall pruning may lessen the quantity of June blooms.
Considerations for pruning hydrangea species commonly grown in New Hampshire gardens
The gigantic blue mopheads or lacecaps known as bigleaf hydrangeas (Hydrangea macrophylla), which are familiar to most gardeners, form their flower heads at the tips of stems on old wood from the previous year. Although lower buds along the stem have the capacity to grow blooms as well, the hydrangea’s blossoming potential is decreased if those buds are died or damaged throughout the winter. Wait until new growth sprouts in the spring before pruning your bigleaf hydrangeas. Approximately 1/4 inch above the first group of live buds, prune the plant. A hint: the interior of living stems will be green, whereas the interior of dead stems will be brown. Cut completely dead stems flush with the base.
The three other hydrangea species that are frequently planted in Fresh Hampshire—oakleaf (H. quercifolia), panicle (H. paniculata), and smooth—all bloom on new growth. Before the emergence of the leaves in the late winter and early spring, remove wasted flowers and prune the plant to improve its general structure and habit.
In conclusion, there are a ton of other activities you can engage in to stay occupied in the garden during fall. Save the spring for hydrangea pruning.
