Hydrangeas have become increasingly popular in gardens and landscapes over the years. Their beautiful blooms make a stunning addition to any outdoor space. However, knowing how to properly prune hydrangeas is essential if you want to ensure healthy growth and abundant flowers each year. Pruning at the wrong time or in the wrong way can lead to fewer blossoms and a less attractive plant.
When it comes to hydrangeas, timing is everything. Different types of hydrangeas bloom on different wood, so it’s important to know what type you have before you start pruning. Bigleaf hydrangeas (Hydrangea macrophylla), for example, bloom on old wood, meaning the buds form in late summer and are there all winter, ready to burst into beautiful flowers in the spring. Pruning these hydrangeas should be done right after they finish flowering, usually in late summer or early fall. By pruning these hydrangeas later in the season, you help protect the next year’s blooms.
Other hydrangea varieties, such as the smooth hydrangea (Hydrangea arborescens), reblooming hydrangeas, and climbing hydrangeas (Hydrangea anomala petiolaris), bloom on new wood. This means they form buds in the spring on the fresh wood they’ve grown over the winter. Pruning these hydrangeas should be done in late winter or early spring before new growth emerges. These hydrangeas are more forgiving when it comes to pruning, so you have more flexibility with the timing.
One common mistake many gardeners make when pruning hydrangeas is to prune them too much. Hydrangeas can tolerate quite a bit of pruning, but removing too much can harm the plant and decrease flowering. It’s important to take a conservative approach when it comes to removing branches and foliage. The bottom-line is to prune hydrangeas to improve their shape, remove dead or damaged wood, and stimulate new growth, without sacrificing too many potential blooms.
Pruning hydrangeas for best bloom
Pruning hydrangeas is an important step to ensure that your plants have the best possible blooms. By using the right tools and following the correct steps, you can enjoy healthy, vibrant flowers year after year.
First, it’s essential to know what type of hydrangea you have, as different types require different pruning techniques. The two most common types are the bigleaf hydrangeas (Hydrangea macrophylla) and the panicle hydrangeas (Hydrangea paniculata).

For bigleaf hydrangeas, which include the popular pink and blue varieties, it’s best to prune them in late winter or early spring. This allows you to identify any dead or damaged wood and remove it, making way for new growth. To prune bigleaf hydrangeas, start by removing any dead flower stems from the previous season, cutting them back to the first pair of healthy buds. Be careful not to remove any new growth that may be developing higher on the stems.
Panicle hydrangeas, on the other hand, should be pruned in late winter or early spring before they start actively growing. These hydrangeas, which often have white flower clusters that turn pink as they age, can be pruned more heavily. Cut back the stems to about one-third of their total height, as this will encourage new growth and larger blooms.
Another popular type of hydrangea is the oakleaf hydrangea (Hydrangea quercifolia), which has unique lobed leaves that resemble those of an oak tree. Oakleaf hydrangeas bloom on old wood, so it’s important not to prune them too late in the season. If you’re unsure when to prune, it’s best to wait until after they have finished blooming and then prune immediately. This way, you won’t risk removing any flower buds for the next season.
If you have a climbing hydrangea (Hydrangea anomala petiolaris), you’ll want to be careful when pruning. These plants have adhesive aerial roots that attach to walls and other structures, so pruning can be tricky. It’s best to prune climbing hydrangeas immediately after they finish blooming, as this will give them plenty of time to produce new growth that will flower the following year.
It’s worth noting that some hydrangeas, such as the Endless Summer series, are repeat bloomers, meaning they can bloom on both old and new wood. This trait allows for more flexibility in pruning, as you don’t have to worry as much about removing potential buds. However, it’s still a good idea to remove any dead or damaged wood to promote overall plant health.
In conclusion, pruning hydrangeas is an important task that can greatly impact the overall health and blooming of your plants. By identifying the type of hydrangea you have and knowing the correct timing, you can confidently prune your plants for the best possible blooms. Remember to use the right tools, such as sharp pruners, and to remove any dead or damaged wood. Follow these steps, and you’ll be rewarded with beautiful, healthy hydrangea flowers.
Hydrangea paniculata panicle hydrangea
The Hydrangea paniculata, or panicle hydrangea, is a lovely variety of hydrangea that produces big, nice blooms. It is known for its large panicles of flowers that bloom from summer to October. Unlike the bigleaf hydrangeas (Hydrangea macrophylla), which bloom on old wood and should only be pruned after they finish blooming, panicle hydrangeas can be pruned in late winter or early spring.
Pruning panicle hydrangeas is a simple process that consists of a few easy steps. Here’s what you need to do:
- Identify the stems that need to be pruned. Panicle hydrangeas typically have fewer stems and a more upright growth habit compared to bigleaf hydrangeas.
- Remove one-third of the stems at the base to encourage new growth and maintain a tidy shape. Be sure to cut just above a bud or side shoot.
- If the panicle hydrangea has grown too large for its location, it can be pruned back more severely. However, keep in mind that this may sacrifice some blooms for the current season.
Panicle hydrangeas are native to Asia and have been grown in gardens for centuries. They are known for their showy blooms that can range in color from white to pink. These hydrangeas are quite hardy and can tolerate a wide range of growing conditions, including full sun to light shade. They are also more resistant to diseases compared to other hydrangea varieties.
The panicle hydrangea is a popular choice for landscaping due to its versatility. It can be grown as a shrub or a small tree, and it can even be trained to climb a trellis or fence. The variety “Incrediball” is particularly popular for its large, round flower heads.
The bottom line is, if you enjoy growing hydrangeas, panicle hydrangeas are a great choice. They are easy to care for and can add a beautiful touch to your garden or landscape. By following the proper pruning techniques, you can ensure that your panicle hydrangeas will continue to thrive and blossom year after year.

Hydrangea macrophylla bigleaf hydrangea
Hydrangea macrophylla, also known as bigleaf hydrangea, is a popular flowering shrub that brings a splash of color to gardens and landscapes. This in-depth guide will provide you with all the necessary information on how to properly prune your bigleaf hydrangea.
Bigleaf hydrangeas are typically found in zones 5 to 9 and come in a variety of colors and flower forms. The two main types within this group are the mophead (macrophylla) and lacecap (serrata) varieties. These hydrangeas typically bloom from midsummer to fall, but their beautiful flower buds often form the previous year on old wood, so timing is crucial when it comes to pruning.
Before we begin, it’s important to know that not all bigleaf hydrangeas require pruning. If your hydrangea has been growing well and looking healthy, it may not need any pruning at all. However, if you want to maintain a more compact and tidy look or if you’re dealing with deadheading, promoting new growth and rejuvenation, then pruning is necessary.
One important step before you start pruning is to identify the type of bigleaf hydrangea you have. The mophead (macrophylla) and lacecap (serrata) varieties have different pruning requirements, so this step is crucial to ensure you don’t harm your hydrangea.
If you have a mophead (macrophylla) hydrangea, which are the most common type, you need to make your cuts just above a set of large, healthy buds. They typically produce flowers on the previous year’s growth, so removing too much old wood can result in a diminished flower display. For deadheading, it’s best to remove spent flowers above the first set of large leaves below the flower head. This will encourage new growth and blossoms.
For lacecap (serrata) hydrangeas, they usually bloom on both old and new wood, so they can be pruned a little more aggressively. You can remove older, thicker stems all the way to the base to encourage new growth and maintain a healthier plant.
When it comes to timing your pruning, it’s recommended to prune bigleaf hydrangeas in late winter/early spring while the plant is still dormant. This will give the plant enough time to recover and promote new growth before the summer bloom. However, if you notice any signs of winter damage, it’s best to prune after the last frost has passed to avoid further harm.
As for the tools you should use, a pair of sharp pruners or loppers will do the job. Make sure they are clean and sterilized to prevent the spread of any diseases. It’s also a good idea to have a trash bag or bucket nearby to collect the pruned branches and debris.
In conclusion, knowing how to properly prune your bigleaf hydrangea is key to maintaining its health and ensuring a beautiful flower display year after year. By following these tips based on the type of hydrangea you have, understanding the timing and using the right tools, you’ll be able to prune your hydrangea without harming it and enjoy its gorgeous blooms for seasons to come.
Hydrangea arborescens smooth hydrangea
When it comes to pruning Hydrangeas, one type that you may come across is the Hydrangea arborescens smooth hydrangea. This type of hydrangea is a member of the broad, panicle group and typically has large, showy blooms. If you have this type of hydrangea in your garden, here are some tips and advice on how to prune it properly.
The bottom-line with pruning smooth hydrangeas is that you don’t need to worry too much about it. These hydrangeas are very forgiving and can even be pruned down to the ground if needed. They will still bloom and bring you joy in the next season.
One popular method of pruning smooth hydrangeas is to do it in late winter or early spring, before new growth starts to appear. To do this, simply cut back one-third of the stems to about one foot above the ground. This will help rejuvenate the plant and promote healthy, new growth.
If your smooth hydrangea has become too big and wide, you can also consider removal pruning. This is a more drastic measure where you cut back the entire plant to about 6-12 inches above the ground. This will reduce the size of the plant and allow it to grow back more compactly.
Another important thing to note is deadheading. Deadheading refers to the removal of faded flowers to promote more blooming. However, with smooth hydrangeas, deadheading is not necessary. The faded blooms will naturally fall off on their own and the plant will continue to produce new flowers throughout the blooming season.
Summary of smooth hydrangea pruning tips:
| Prune in late winter or early spring |
| Cut back one-third of the stems to about one foot above the ground |
| Consider removal pruning if the plant is too big and wide |
| Deadheading is not necessary |
Overall, pruning smooth hydrangeas is a relatively simple task. Just remember to prune in the right season and don’t be afraid to cut the plant back if needed. With a little care and attention, your smooth hydrangea will continue to bloom and bring beauty to your garden year after year.
