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.
What occurs if hydrangeas are not deadheaded?
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.
If deadheaded, do hydrangeas bloom again?
Hydrangeas cannot be revived by deadheading like other flowers can. Reblooming hydrangeas produce a second set of flowers on fresh stems later in the season compared to regular kinds, which only bloom once each season. When deadheading hydrangeas, the goal is to keep the shrubs looking tidy and to direct plant growth toward roots and leaves rather than seeds.
When should hydrangeas be deadheaded?
Myers asserts that how you deadhead your hydrangeas is just as crucial as when you do it. Make your incision directly above the first set of full-sized leaves, which should be situated beneath the blossom, she instructs. “You are essentially eliminating the faded blossoms to expose a set of sound leaves. This can be carried out immediately following flowering, in late winter or early spring.”
In the summer, do you deadhead hydrangeas?
You ought to be deadheading the spent flowers all through the flowering season. Just above the first pair of leaves that are opposite one another, follow the stem down. You should cut this off to promote new growth.
Your hydrangeas will look better overall and be ready for the next year if you deadhead them. Early April is when the hydrangea growing season begins. The shrub’s longer branches can be clipped by gardeners to display the hydrangea blossoms in vases. Early summer is the ideal time to deadhead to encourage growth.
Your hydrangea is most likely developing new buds for the following year after August. It’s a strong, positive plant! Before cutting, run your fingertips down the stem to feel for any bulging new flower buds. Make sure to avoid any bumps you feel or see by cutting safely over them.

What makes deadheading and trimming distinct from one another?
Fortunately, all you need for this project are some clippers, gloves, and a pail to gather your cuttings. I really appreciate this multi-snip tool that I discovered last spring for this gardening task because deadheading is typically a little more delicate than full-on trimming. Use anything you have, including regular bypass pruners.
Since I normally go through 1-2 pairs of gloves in a season (due to holes in the fingertips…), I bought these gloves last spring. I was impressed by how lightweight but robust they are. Since I have spare pairs accessible for any garden assistance I may hire, I haven’t even pierced the first pair’s fingertips yet.
General Pruning-Deadheading Tips
(Note: pruning refers to removing any portion of the plant, from large to small – what we’re doing in the summer is small, just cutting back some and trimming.) Deadheading is the practice of removing wasted flowers from plants.
The majority of your perennials and shrubs that have bloomed or are still blooming only require that you “deadhead,” or cut off the spent blossoms. To determine where to cut the dead flower, consider the following two factors:
- Like this buddleia in the picture above, you can prune it back to the first sign of new growth. This small variety (Lo & Behold ‘Ice Chip’) will continue to bloom into the fall thanks to those new stems on the sides that will bear additional flowers.
- OR, you might prune it more, taking further cuts to keep it under control for the planting area. To prevent the plant from getting too huge or to assist it maintain a more aesthetically acceptable form, continue to look for new growth, but further down on the stems.
You’ll also find plants with dead flower stalks and leaves, like the daylily in this image. Your garden will look better into the fall if you take the effort to remove the browning, dead leaves and deadhead the flower stalks. The majority of daylilies have finished flowering, but they will continue to provide grass-like leaves as a backdrop to the garden. However, some types, like Stella d’Oro, will continue to bloom if the dead stalks are removed.
Shearing the plant back is the simplest approach to get rid of all the wasted flowers on perennials with tiny blooms, like hardy geranium. Once the majority of the wasted blooms have been removed from the plant, grab pieces with your hand and chop the entire part off. For a week or two, it won’t look its finest, but it will soon sprout new growth and produce more blooms.
The heavy blooms on mature hydrangeas may be causing the plant to bend and dip, exposing the crowns. It’s the ideal moment to remove the oldest blossoms, especially those at the bottom, so that the leaves can reposition themselves. If you cultivate a reblooming hydrangea, such as Endless Summer, it will keep producing new flowers for you.
The act of gathering all the blooms and decorating the home with vases of fresh flowers after hydrangea trimming in the summer is the greatest part!
You’ve undoubtedly been deadheading individual rose blossoms as they appeared over the previous few months, but your shrub will bloom more quickly if you trim back to a five-leaf junction, where new growth and blooms will develop.
Additionally, you should prune back to new growth to remove any damaged leaves and stems (like I obviously have on some of my roses – if you live in the Pacific Northwest, every rose will get blackspot…). This not only improves the appearance but also helps prevent disease from spreading to the new 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.
What should hydrangeas be used for after flowering?
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.
Are hydrangea blooms chopped off?
When should I prune my hydrangeas? is one of the most often asked gardening topics. We all have a tendency to want to hurry outside with the clippers and start hacking away when those billowy large flowers change from cheerful blues, purples, pinks, reds, and whites to uninteresting browns.
When to Cut Back Hydrangeas
The timing will vary according on the variety of hydrangea you have. First of all, be aware that hydrangeas do not require pruning unless the shrub has become unruly or too big for its location and requires some shaping up. Otherwise, simply deadhead wasted blooms and remove any dead branches from the plant.
How to Prune Hydrangeas02:07
But if you do decide to prune one, bear in mind to time it so that it blooms on old wood or new wood depending on the species of hydrangea you have.
If you wait too long, you can chop off the buds that are developing on old wood (stems from the year before the current summer), which would prevent flowers from blooming the following spring. Therefore, as soon as the flowers on these bushes have faded, they should be clipped.
The shrub should be clipped in the early spring before that new growth appears, but, if the shrub flowers on fresh wood (stems generated during the current season), which means that its buds are set inside the season.
Should I remove the fall blossoms on my hydrangeas?
Maintaining your hydrangea can greatly impact its blooms the next year. When given enough time and the right care, hydrangeas are resilient and can recover from virtually anything.
See our comprehensive growth guide for hydrangeas here after reading the fall maintenance advice below!
Because some hydrangea kinds do not like to be clipped in the fall, it is crucial to first identify your variety.
If you have hydrangeas in your garden, you should be aware that there are two different varieties. Both types develop blossom buds, one on new wood and the other on old wood. If a stem has remained on the plant since the previous summer, it is referred to as old wood. Stems that form this season are considered new wood. The majority of hydrangea species that are found in gardens are old wood bloomers, including as Mophead, Big Leaf, Lacecap, and Oakleaf types. Check your variety once more at the neighborhood garden center.
Hydrangeas can grow for many years without being pruned, but it’s time to cut them if they become unkempt, take over a portion of the garden, or stop producing new growth. But when should they be pruned?
After the summer blooms on old wood bloomers or fall blooming hydrangeas, prune them. Old, woody hydrangeas that are pruned in the fall will not bloom the following season.
Hydrangeas that bloom in the summer or those that do so on fresh wood are clipped in the fall, after their flowering season has ended.
Early in the season, hydrangeas are brilliant and colorful, but they are difficult to preserve after being cut. Once they begin to dry on the bush, they are simpler to maintain.
Your plant will have weak, wispy growth near the bottom. Reduce them. They will consume energy that could be used by your plant to produce blossoms.
On your stems, look for any dead stumps. They won’t have sprung any buds or new wood from the original old wood. To totally remove the dead stumps, cut them to the ground at the base. This will give the new growth below a chance to flourish.
To make way for new buds to emerge, old and dead blossoms must be eliminated. To promote flowers for the following summer, remove the flower head immediately above the first few leaves.
Observe the plant’s shape from a distance. The shrub should be pruned into the shape you desire; a spherical is the traditional shape, but you can prune it however you like!
Clean up any leftover debris from the plant’s foundation. Make sure your soil is devoid of all weeds, dead flowers, and leaves.
Feed your blue hydrangeas with Holly-tone to maintain acidic soil and vibrant flowers. Alternatively, choose Flower-tone.
Feed your hydrangeas two to three times each week from spring till fall for the greatest results.
Your hydrangeas will remain healthy and vibrant for many years if you follow these simple instructions.
