Remove up to one-third of the older living stems from the hydrangea each summer, cutting them all the way to the ground. The plant will recover as a result. Before the end of July, if required, prune back the plant to regulate its growth and give the buds time to grow. Usually, the plant grows back to its previous size right away.
Does hydrangea growth occur on new or old wood?
Some hydrangea species, known as “old wood,” bloom on growth from the previous year. The flower buds that will bloom in the upcoming summer are present in this old wood. We would have a plant without flowers this year if we pruned in the winter or spring because we would lose the flower buds. As a result, many cultivars undergo pruning following summer blooming.
The young growth that appears in the springtime bears flower buds when hydrangeas that bloom on new wood are present. These plants can be clipped in late winter or early spring before new growth starts because the buds are not present during the winter months.
Do I need to remove the dead stems from my hydrangea?
First and first, it’s crucial to understand that mophead hydrangeas never need to be cut back, unless they are quite old. The only pruning necessary for the plant’s health is the removal of dead stems, which can be done whenever you like. Additionally, dead blooms can always be removed.
However, if your hydrangea is getting much too big (or old) and has to be pruned, utilize one of the techniques listed below.
If you have mophead or lacecap hydrangeas (the only varieties that are often blue or pink) or oakleaf hydrangeas, use Method One (leaves shaped like large oak leaves, white blooms).
If you have paniculatas (PeeGees) or “Annabelle,” use Method Two (arborescens). PeeGee and smooth hydrangeas have white blooms.
What are Woody hydrangeas used for?
Hydrangeas are robust plants that need little maintenance from us and consistently produce jaw-dropping flowers. However, hydrangeas can occasionally turn woody and appear to have more dead wood than leaves and blooms. It can even appear that the base of the hydrangea is little more than a few sticks with very little green growth. What then should you do to fix a woody Hydrangea when this occurs?
To foster new growth and eliminate dead or dying stems, woody hydrangeas can be trimmed back.
Just be sure to prune during the appropriate season! This “woodiness” can occasionally be a result of damage from harsh winters, but it can also develop naturally as a Hydrangea ages. Thankfully, these tough plants may recover from a severe pruning and start producing lovely flowers again.
A word of caution: Keep in mind that all Hydrangeas appear dead throughout the winter before you go all Edward-Scissor-Hands on your plant. All that is left when the leaves wither away are few naked sticks. This is entirely normal, so don’t be alarmed. As you cannot tell if your Hydrangea has genuinely become too woody until spring or summer, when it begins to produce buds and blooms, you will need to wait a bit to get a good appraisal of your shrub.
What does dead wood on a hydrangea look like?
Which wood in this picture is alive is clear thanks to spring. While the majority of the tips are dead and still naked, the live wood has pushed forth new leaves.
A: This previous summer, we planted some fresh hydrangeas, and they went half-dead before coming back in the fall. Some branches never produced new leaves. Are they deceased? When should I clip them, if so?
A: With fresh plants, that can occasionally happen. Coming out of the containers and into the open ground with frequently poor soil and more inconsistent care than the plants likely received at the nursery is a shock.
The last growing season’s hot, dry late summer wasn’t great for establishing newly planted plants.
The color and density of the wood will help you distinguish between live and dead hydrangea branches. In comparison to live wood, dead wood will appear more gray and be lighter and less dense.
Getting rid of any dead wood is no longer a concern. It won’t harm to leave all growth unchecked.
The emergence of leaf buds in the spring will make it extremely clear which wood is alive and which is dead.
Most years, by May, growth has resumed, and it is a good time to prune both dead wood and any dead tips (straight back to the ground if the entire shoot is dead).
You definitely don’t want to prune live wood in the spring if these bigleaf hydrangeas (Hydrangea macrophylla) are any indication.
Performing a general size-control whack-back in the spring will result in you losing all or most of your flowers because these hydrangeas bloom on buds that formed the previous season.
Severe winters can also damage those buds, which is why we’ve had two consecutive years with few hydrangea blooms after the previous two bitterly cold winters.

Why are the branches on my hydrangeas going brown?
- Drought, excessive wind, and too much sun can cause the leaves and blooms of hydrangeas to turn brown. The best conditions for hydrangea growth are protection from wind, wet soil, and dappled sunlight. The hydrangea blooms and leaves wilt and become brown because there is insufficient moisture around the roots.
- When hydrangeas are planted in small pots, the leaves and blossoms become brown because the roots can’t properly absorb moisture from the soil in the smaller pots. Because of their large root systems, hydrangeas need constant watering to keep their leaves and petals from turning brown.
- The hydrangea’s leaf edges get brown and crispy when fertilizer is applied excessively or too frequently. Applying a delayed release fertilizer at the beginning of spring will help prevent the bronzing of the leaf margins since hydrangea roots are extremely sensitive to excess fertilizer.
- The flower buds and newly developing foliage development of hydrangeas can become dark and mushy in the Spring due to a late frost. The young growth is delicate and more susceptible to damage from frost. Cut back any hydrangea flower buds that are brown and mushy because they won’t bloom.
- Hydrangea leaf spot fungus, which results in brown patches on the leaves, is typically brought on by overwatering. A hydrangea with dark spots and fewer flowers has too much moisture on its leaves, which encourages the growth of a fungus.
What occurs if hydrangeas are not pruned?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.
How far back should hydrangeas be pruned?
Before performing any significant “hard” trimming, let these plants grow for one or two seasons. Depending on whether you want a smaller or larger shrub, prune these hydrangeas in the spring to the ground or not at all once the shrub is established and has had a few growing seasons. On the growth from this season or fresh wood, flower buds will develop.
Favorite smooth hydrangeas include:
- (H. arborescens ‘NCHA7’ PP30,358) Invincibelle Mini Mauvette
- (H. arborescens ‘Abetwo’ PP20571) Incrediball
- The Annabelle tree (H. arborescens)
Should I remove the brown blooms on my hydrangea?
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.
How should hydrangeas that bloom on fresh wood be pruned?
On the growth of the current season, hydrangeas that bloom on fresh wood place their flowering buds. They can be pruned virtually any time of year, with the exception of the summer, as their blossoms develop from new growth at the plant’s base. To keep these varieties of hydrangeas healthy and vigorous, follow these three steps:
- To enhance the shrub’s appearance, remove faded blossoms in late summer.
- Older canes should be removed to increase vitality.
- In late winter, before the onset of new growth, completely prune the shrub.
Other tips include leaving some of the older branches to serve as a support structure for new development (these types of hydrangeas tend to open up and get floppy.) Additionally, many gardeners advise trimming bushes all the way back to the ground, as this frequently results in larger blossoms.
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.
