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.
Do you remove hydrangeas’ dead flowers?
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 favour by deadheading because this strengthens and makes plants healthier.
When should hydrangeas have their dead blossoms removed?
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.”
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 vigour.
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 towards roots and leaves rather than seeds.
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 tonne of other activities you can engage in to stay occupied in the garden during fall. Save the spring for hydrangea pruning.

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 towards 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.

Do I need to remove the Brown hydrangea leaves?
If newly emerging hydrangea leaves or flower buds are exposed to a late-spring frost or chilly winds, they will turn brown. A unexpected cold spell can harm the newly emerging buds and leaves, which are exceptionally delicate and susceptible to injury. This can cause the buds to turn brown and wither away.
Naturally, hydrangeas grow in protected regions under trees that block chilly winds and produce a more stable microclimate that allows the young flowers to open up without facing a serious risk of frost.
Hydrangeas’ newly formed buds and leaves can become mushy and their leaves can turn brown when they sustain frost damage.
Since it is more exposed to the environment, the outermost growth is typically the one that suffers from the worst damage.
Sadly, the harmed flower buds are therefore unable to bloom, and the freshly growing growth is probably not going to recover.
Frost damage to hydrangea flower buds and foliage is more common in exposed areas, so plant or move your hydrangea to a more protected area of the garden, close to your house, or close to some other plants and hedges.
Particularly hedgerows are great wind breakers since they shield your hydrangea from the elements and might lessen the effects of frost.
There isn’t much you can do to save flower buds or younger leaves after they turn brown. As a result, prune back to healthy growth any growth that has been harmed by the frost.
In contrast to the flower buds on the plant’s outermost part, which are naturally less protected, hydrangeas frequently have growing flower buds farther down each branch. These flower buds typically survive a frost.
This implies that your hydrangea can still bloom, but much later and with fewer flowers emerging. With a little patience, you should still be able to enjoy some lovely blooms throughout the Summer.
Do I need to remove the dead flowers?
Simply taking off the dead flower heads from your plants is known as deadheading. I’ve got good news for you if you’re new to gardening and are wondering how to deadhead a flower—deadheading is simple! And eliminating dead flowers has a number of advantages. In addition to improving a plant’s appearance, the procedure also prevents seeds from sprouting and encourages your flowers and plants to keep growing thicker and fuller than before. This simple gardening task doesn’t take much time or thought if done frequently. While on the phone or watering the garden, I enjoy deadheading plants. I actually find it to be calming (and satisfying, believe it or not; when I’m finished and the garden is crisp, clean, tapered, and tailored, it was well worth the time in the sun).
How to Deadhead Flowers
If pruning and deadheading your flowers makes you cringe, try not to picture the daunting task of doing it all at once. Instead, divide your yard into portions and work on it gradually. The procedure could be relaxing and joyful for you. Simply go outside to the garden whenever you have a few spare minutes to take care of a little deadheading maintenance, one area at a time. I like to always have a small bucket, Fiskars PowerGear2TM Pruner, and Fiskars SoftGrip Micro-Tip Pruning Snips on hand. When you’re prepared, simply carry out these actions:
1. Deadheading should be timed. When deadheading flowers, timing is actually not a concern. Throughout the entire growing season, from spring through fall, this gardening task can (and should) be completed. Flowers can be deadheaded whenever they start to wilt. Single blossoms on single stems make this obvious. When 70% of the blooms have faded, plants having several blooms on a stalk, such as salvia, begonias, and delphiniums, should be deadheaded.
The type of plant and the climate will determine how frequently you should deadhead. You might want to give some plants a chance to set seed towards the end of the summer and into the fall. Some plants produce eye-catching seed heads that, during the cooler months, serve as food for wildlife.
2. Decide where to clip a deadhead.
It could be difficult to decide which place to deadhead. You can end up with a dry and ugly stem if you cut near to the bottom of the flower. Depending on the species, there may be different places to deadhead or prune a plant. Deadhead your spent flowers and stems down to 1/4 inch above a fresh lateral flower, lateral leaf, or bud as a general rule of thumb. This promotes fresh growth and wholesome foliage.
3. Cut off the deadhead. I like to use my Micro-Tip Snips to deadhead most plants, even if others can just be pinched. They let me to reach into a plant rapidly and make a precise cut with no harm to the plant.
Stronger tools might be necessary for larger, woodier stems, like roses. I use my PowerGear2TM Pruners to make precise, clean cuts on these plants. A 45-degree angle should be used for cutting larger stems. This lowers the possibility of illness or harm.
4. Quick and simple cleanup.
Don’t put your wasted blossoms on the ground because the main goal of deadheading plants is to make your flower beds appear great. To dispose of them in your compost pile, it’s as simple to collect them in a little bucket.
5. Fertilize to support ongoing growth. Pruning and deadheading flowers promote fresh growth. Keep your fertiliser regimen consistent to ensure that your plants continue to grow robustly and healthily. Annuals are particularly voracious feeders. All the nutrients your flowers require for sustained flowering will be provided by regular water-soluble fertilisers with balanced proportions.
Why Do I Need to Deadhead My Flowers?
Beyond just enhancing our surroundings with a kaleidoscope of colours, flowering plants provide a variety of functions. Bees, butterflies, beetles, and birds are just a few of the pollinators that benefit from the nectar and pollen of a blossom. Even the plant itself might offer animals a secure haven and home. The fruits, berries, and nuts that appear after your lovely blooms have faded provide food for both people and wildlife.
A plant’s main objective is to multiply. Even if we only consider the blooms as the reward for a healthy plant, the plant itself serves a vital purpose for future generations. The genetic material that enables plants to develop new generations year after year is included in the seeds they produce. Therefore, after producing a round of successfully pollinated flowers, a plant turns its attention to producing seeds. In order to secure the continuation of their species, both annuals and perennials invest energy in generating seeds.
These seed-bearing nuts, berries, and fruits—from the perspective of the plant—contain the genetic material required for the plant to develop offspring. Therefore, after your pretty plant has produced a successful round of beautiful flowers that have been pollinated, it turns its attention and resources to producing those seeds. This is particularly noticeable for crops used to produce food. After all, don’t beautiful tomatoes, hefty pumpkins, protein-rich sunflower seeds, and sweet apples represent the ideal? But in order to revive your tender plant and urge it to flower once more, remove the deadheads when plants like petunias and roses stop blooming in the early summer. So the deadheading procedure starts.
Flowers That Benefit from Deadheading
Not every bloom needs to be deadheaded. Most bulbs, including peonies, liatris, and others, only produce one round of flowers each season. Periwinkle, impatiens, and the majority of flowering vines don’t require deadheading. Several of my favourite bloomers are among the annuals and perennials that respond well to deadheading and will give you a complete flower display all season long. My list of flowers to deadhead includes:
- Zinnia
- Cosmos
- Marigolds
- Delphiniums
- Hollyhocks
- Germaine Daisy
- robust geraniums
- Petunias
- Snapdragons
- Roses
- Flower Throws
- Bee swabs
- Campanulas
- sour peas
- Salvia
Deadheading Annuals vs. Perennials
Even while deadheading many annuals and perennials only requires removing old blooms, there are a few methods that work best for perennials.
Cutting Back Perennials
No matter how often you deadhead a few mounding perennials, such Coreopsis and Perennial Salvia, their appearance begins to deteriorate. A thorough pruning, often referred to as cutting down, can revitalise plants and keep your landscape appearing neat and orderly. My mounding perennials are best pruned back after the majority of the blooms have disappeared. Using my PowerGear2TM Hedge Shears to cut the entire plant at a height of about 2 inches above the ground is the simplest way to prune back perennials.
Pinching Back Perennials
While technically not deadheading, pinching back some perennials that bloom in the fall throughout the growing season will promote rich, full growth. Mums in the fall, for instance, respond to pinching back really nicely. Despite the fact that it’s technically “pinching back,” what you’re doing is chopping off the growing tips and around 3 inches of growth. In the spring, when the plants are 8 to 10 inches tall, again during the summer solstice, and finally on July 4, I like to give my mums three cuttings. Once they bloom, deadheading your mums on a regular basis will keep them looking lovely. Pinch-backing is also beneficial for perennials like common yarrow, cardinal flower, and goldenrod.
