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.
Should you remove hydrangea blooms that are wilting?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
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.
Should I prune my hydrangea’s dead heads?
Since their flower heads were left on during the winter to preserve the buds underneath, most hydrangeas are clipped in the spring. The exception to this rule is climbing hydrangeas, which are clipped in the summer after blossoming.
Hydrangeas can avoid becoming woody and crowded by being pruned, which also directs the plants’ energy toward strong growth and big blooms. Apply compost or well-rotted manure as mulch to the plant after pruning.
As some hydrangea varieties flower on old wood while others do not, different hydrangea varieties require different pruning techniques. Inadequate pruning will have an impact on flowering.
Cut back the old flower heads to a pair of buds below on Hydrangea macrophylla, Hydrangea aspera, Hydrangea serrata, and Hydrangea quercifolia. You can prune Hydrangea paniculata and Hydrangea aborescens more severely.
It’s best to merely deadhead your hydrangea and watch it grow if you’re unsure of what kind it is. You can prune it more severely the following year if you see that it blooms on the growth from this year.

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.
Which month do you prune back hydrangeas?
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.
Are hydrangeas deadheaded in the winter?
Some hydrangeas, but not all, can be deadheaded, or the wasted flowers can be removed off the stem to promote better blooming later.
Only after blossoming in moderate climates, according to the RHS, should dead blooms on mophead hydrangeas be removed. According to their suggestions, it is preferable to leave the flowerheads on the plant throughout the winter to offer some frost protection.
Additionally, by leaving the dried blooms on the plant, you’ll keep the garden interesting through spring and they can make a beautiful sight when coated in frost.
However, after blossoming, the blooms on the more resilient lacecaps can be deadheaded.
Do hydrangeas bloom throughout the summer?
Historically, hydrangeas only had one blooming season. No longer! You may now pick from a wide selection of hydrangeas that bloom all summer long. Even now, you can prune these.
With reblooming hydrangeas, you can enjoy blossoms from June until the first frost since they bloom on both new and old growth. They’ll keep blooming long after other perennials and bushes with flowers have finished. Long-lasting flowers in shades of blue, violet, pink, white, or chartreuse give any garden vibrant splashes of color.
These hydrangeas also pull off a spectacular act. The color of the hydrangea varies according to how acidic your soil is. Beautiful blue hydrangeas are quite simple to make. All you have to do is add Espoma’s Organic Soil Acidifier to your soil.
The Authentic Hydrangea of Endless Summer
A gorgeous game-changer! The first continuously flowering hydrangea was called the Original Endless Summer. It’s also simple to maintain. Its season-long color-changing blossoms will amaze you.
late spring to early fall for blooms. Depending on the soil’s pH, blooms might be blue, purple, or pink.
Examine the blooms for signs of damage.
Look for hydrangeas at the store that have vibrant, robust green leaves and bouncy blossoms. Check the petals for any brown spots, which would signify sun damage, advises BloomThat’s production director Callie Bladow. “Additionally, because cut flowers are stored cold, keep an eye out for black petals that could mean the blooms have been in contact with a refrigerator’s side. A flowering hydrangea should feel solid, not flimsy or spongy.” A healthy bouquet should last up to two weeks if you select one.
Cut garden-grown flowers with a sharp floral knife.
If you’re fortunate enough to have garden hydrangeas, you may easily bring them inside for a lovely arrangement. While working outside, cut them on the bias (a 45-degree angle) using a sharp flower knife or clean kitchen shears, then put them in a dish of lukewarm water. The optimal time of day to trim hydrangea blossoms, according to Bladow, is early in the day. “Leave the others to continue blooming and just select the most fully developed and mature blooms. Hydrangeas with full flowers will appear more “papery” than those with young buds.”
Prep them with alum powder.
The sap that hydrangeas create at the base of their stems needs to be sealed off in order for them to absorb water. After making a bias cut in the stem, Bladow advises dipping it in alum powder, an onion powder that can be found in the spice section of your local supermarket. “All that’s needed is a quick dip of the stem’s bottom, followed immediately by the vase.” If you don’t have alum powder, you can get the same result by dipping the stem in boiling water for around 10 seconds. Additionally, cut the leaves off the stem because they will use up all the water in the vase.
Get creative arranging with different flowers.
You can choose to use a traditional arrangement of only hydrangeas or you can try blending in other flowers or utilizing unusual vases. Bladow explains, “I adore utilizing glass apothecary jars with larger bases and petite vase necks. “Another way we enjoy using hydrangeas in our designs is as grids for other flowers. Simply insert them into the flower head; the hydrangea’s multiple stems will hold other flowers in place.” Hydrangeas can be arranged with any kind of flowers. She suggests combining some foliage, such as lemon leaf or variegated pittosporum, with roses, dahlias, and freesia.
Change the water daily.
According to Bladow, hydrangeas prefer chilly water, which should be replaced every other day with a new snip of the stems. You can fill the vase with some plain cane sugar or flower food from your cupboard. Keep your arrangement away from harsh sunlight. Additionally, Bladow advises soaking the entire hydrangea for around 45 minutes in cool water if your flowers are acting downcast. Shake them off, trim the bottom of the stem, and then submerge them in flower food-infused water. Your hydrangeas’ lifespan could be extended and they might even come back to life.
