Depending on the kind you have, you must prune your hydrangeas correctly. Different hydrangea varieties need to be pruned at various times of the year.
For instance, you should hold off on pruning smooth hydrangeas like Annabelles until they are through blooming. All summer long, new blooms will result from pruning done in the late fall or early spring, before new growth starts.
Big Leaf and Oakleaf hydrangeas should only be pruned in the early fall to avoid cutting off buds that might otherwise prohibit summer blooming. It’s advisable to prune these hydrangea varieties as soon as they finish blooming.
Although Paniculata or PeeGee hydrangeas are a little more adaptable, they should still be clipped in the early spring before new growth starts.
Should you remove hydrangea tree blooms?
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.
Should hydrangeas be pruned back during the winter?
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 may a hydrangea tree be cut?
I have a hydrangea tree, but because the branches are excessively long, they bend downward to the ground when it rains. Can I prune branches back, and if so, when should I do it?
Yes, you can prune it, but first it’s important to define a hydrangea tree so you can understand how and why.
A panicled or PG hydrangea (Hydrangea paniculata) is actually a hydrangea tree that has been deliberately pruned to resemble a tree. Depending on the cultivar, it develops huge, elongated clusters of white or lime-green blooms at the tips of its branches in the summer that progressively turn pink or even scarlet in the fall. Since few other kinds of hydrangea have stems robust enough to create decent trees, it’s very much the only one used in this method.
The panicled hydrangea typically develops into a sizable multi-stemmed shrub. It grows an abundance of branches from its base and develops an erect, spreading shape over time, eventually reaching a height and diameter of up to 15 feet (5 meters) after 15 to 20 years. It’s obvious that it’s a shrub because it doesn’t resemble a tree in its natural state.
The nurseryman selects a young specimen with a strong central branch and starts to shape it into a hydrangea tree “prune it until it yields. He cuts off any more branches and any secondary branches that develop on the branch that will eventually serve as the trunk. During the first few years, staking is frequently required to maintain the trunk’s strict verticality. He starts trimming the top of the plant as well after the trunk has grown to the appropriate height, which is often 4 to 5 feet/1.2 to 1.5 meters. Because of this, the hydrangea is compelled to grow numerous branches at the top of a primary stem, or new trunk.
The process of making a hydrangea tree is time-consuming and significantly raises the price of the plant.
If you like, you can prune a hydrangea by yourself to resemble a tree, but it will take some time.
If you want to keep a hydrangea tree healthy, you’ll need to be prepared to prune it on a regular basis. If you don’t, the branches will grow too long and begin to bend under their own weight, as you’ve seen, and they may even break off, especially when there is heavy snow on top of them.
In your situation, it would be advisable to prune your hydrangea tree before winter because it is overgrown and the limbs are already bending from the weight of the plant. Simply prune all branches back to a distance of 6 to 8 inches (15 to 20 cm) from the top of the trunk in October or November if you don’t want them to risk breaking off in snowy or icy conditions.
Starting pruning early in the spring as opposed to the fall will help your hydrangea tree survive the winter. This is because you’ll want to keep the panicled hydrangea’s dried flower heads until spring because they are lovely over the winter.
Make it a practice to trim back all the branches early in the spring, before the leaves emerge, by 6 to 8 inches (15 to 20 cm). This will give your tree the intended effect, which is typically a ball of greenery topped with blossoms at the summit of a short trunk. Panicle hydrangeas bloom from new growth that begins to appear in mid-spring, so they will continue to bloom profusely even after harsh early-spring trimming.
In order to keep its tree-like look, with a clearly “Remove any suckers that develop at the plant’s base and any growth that develops on the trunk itself. This type of pruning is suitable for all seasons.
The optimal growing conditions for panicled hydrangeas are full sun or very little shade in virtually any well-drained soil. They can thrive in zones 3 to 8 and are cold hardy.
Shape of the Flower Head
- A paniculata type is most likely present if the flower head is formed like a cone.
- It is either a macrophylla or an arborescens kind if the flower head resembles a ball or a flat disk. Visit the section on Flower Color.

Flower Color
- A macrophylla type is present if newly opened blooms feature blue, purple, or pink blossoms.
- An arborescens type is present if the flower buds initially seem green, then turn white, and finally turn green or greenish brown as they ripen.
- You likely have a macrophylla kind if the flowers are white when they first open and remain white as they age. Although they are less common, white flowered macrophylla varieties do occur.
Note: Recent breeding is beginning to develop arborescens with flowers that have a pink tint, such as “Eco Pink Puff.” Future cultivars should have a stronger version of this pink.
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.

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.
Do you prune hydrangeas in the autumn?
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.
