How to Trim Hydrangea in Fall for Optimal Growth
How to Trim Hydrangea in Fall?
To properly trim hydrangeas in the fall, it is important to identify the type of hydrangea you have.
Certain types, such as Hydrangea macrophylla and Hydrangea quercifolia, bloom on old wood and should not be pruned in the fall as it may cut off next year’s flower buds.
On the other hand, hydrangeas like Hydrangea paniculata and Hydrangea arborescens bloom on new wood and can be pruned in the fall without affecting next year’s blooms.
If you have a hydrangea that blooms on new wood and want to reduce its size, light pruning is usually sufficient.
It is also recommended to cut off dried flowers in late fall to prevent branches from splitting under heavy snow.
Additionally, dead branches can be cut off in the fall or whenever they are noticed.
When pruning, it is important to cut the stem at an angle directly above a live bud.
Not pruning hydrangeas in the fall will not harm the plant and may result in more blooms the following year.
It is also recommended to remove spent flowers and dead wood in early spring.
Lastly, if you are unsure about the type of hydrangea you have, checking the plant label or consulting a garden center for identification is a good idea.

Did You Know?
1. Although many people think that hydrangeas bloom from the previous year’s growth, certain species, such as the ‘Endless Summer’ hydrangea, can actually bloom from both old and new growth, making it easier to trim them in the fall without sacrificing next year’s blossoms.
2. Did you know that the color of hydrangea flowers can vary depending on the soil’s pH level? Acidic soil produces blue flowers, neutral soil produces pale white or cream, and alkaline soil produces pink or purple blossoms. This fascinating phenomenon gives gardeners the ability to manipulate the flower color by altering the soil’s pH.
3. When it comes to pruning hydrangeas in the fall, it’s essential to know the difference between pruning for shape and pruning for size. If you want to maintain the plant’s natural shape, you should only remove dead or damaged wood. However, if you need to control its size, you can cut back up to one-third of the shrub, trimming just above a set of strong buds.
4. Some hydrangea varieties, like the oakleaf hydrangea (Hydrangea quercifolia), produce stunning fall foliage in addition to their beautiful blooms. In autumn, the oak-shaped leaves turn vibrant shades of red, orange, and purple, creating a spectacular display in your garden.
5. While hydrangeas are generally hardy plants, some species may benefit from winter protection. In colder climates, you can shield the shrubs by creating a simple burlap barrier or wrapping them with frost cloth. This extra layer of insulation helps protect the plants from extreme temperatures and reduces the risk of winter damage.
Necessary To Prune Hydrangeas In Fall?
Pruning hydrangeas in the fall is a common gardening practice, but many gardeners wonder if it is necessary. The answer is that it depends on the type of hydrangea you have in your garden and its blooming habits.

Benefits Of Not Pruning Hydrangeas In The Fall
If you have hydrangeas that bloom on old wood, it is important to note that not pruning them in the fall will not harm the plant. In fact, it may result in more blooms the following year. By leaving the old wood intact, you allow the plant to continue developing flower buds for the next season. Additionally, leaving dried flowers on the plant can provide a natural barrier against harsh winter weather. The dried flower heads can catch and hold snow, providing insulation for the branches and reducing the risk of splitting under heavy snowfall. Therefore, if you have hydrangeas that bloom on old wood, consider not pruning them in the fall to maximize their blooming potential and protect the plant throughout the winter.
Overall, whether you should prune hydrangeas in the fall depends on the type of hydrangea you have in your garden. Understanding the difference between hydrangeas that bloom on old wood and those that bloom on new wood is crucial for proper pruning. By checking the plant label or consulting a garden center for identification, you can determine the type of hydrangea you have and make informed decisions about pruning.
When it comes to pruning, light pruning is usually sufficient for hydrangeas of the right size for your garden. Removing dead branches can be done in the fall or whenever they are noticed, while cutting off dried flowers for a tidier look can be done at any time. When pruning, it is important to cut the stem at an angle directly above a live bud. This helps promote healthy growth and prevents the stem from developing a flat surface that can collect water and potentially lead to rot.
pruning hydrangeas in the fall requires careful consideration of the type of hydrangea you have and its blooming habits. While some hydrangeas, such as Hydrangea macrophylla and Hydrangea quercifolia, should not be pruned in the fall as it may cut off next year’s flower buds, others like Hydrangea paniculata and Hydrangea arborescens can be pruned in the fall without affecting next year’s blooms.

By understanding the blooming habits of your hydrangeas and following proper pruning techniques, you can ensure optimal growth and a beautiful display of blooms in your garden.
Frequently Asked Questions
How and when to prune hydrangea?
To properly prune hydrangeas, it is advisable to trim back the stems just above a plump bud, known as a heading cut. The ideal time for this is in the fall, late winter, or spring. Given the conical shape of their flower heads, it is recommended to retain the dry, tan flower heads during winter to add visual appeal to your landscape. Consequently, it is often best to postpone pruning until late winter or spring.
What is the best time of day to cut hydrangeas?
The ideal time to cut hydrangeas is in the early morning, when the temperature is still cool. By doing so, your flowers will remain fresh as they have not been exposed to the hot sun for extended periods. This freshness directly translates into a longer lifespan for your hydrangeas when arranged in a vase. Additionally, it is advisable to wear gloves while cutting the flowers to protect your hands and maintain the cleanliness of the blooms.
Can I prune Limelight hydrangea in the fall?
Pruning Limelight hydrangeas in the fall can be beneficial for maintaining their full and lush appearance. It is recommended to prune away any dead branches and trim back about a third of the growth during this season. However, it’s crucial not to wait too long, as pruning too late can result in cutting back the new wood where the hydrangea blooms, ultimately leading to a loss of those beautiful blossoms. Therefore, carefully timing your pruning in the late fall or early spring is essential for ensuring the continued beauty of your Limelight hydrangea.
Do you cut hydrangeas when they turn brown?
Yes, it is beneficial to cut hydrangeas when they turn brown. This process, known as deadheading, involves removing the faded or brown flowers from the shrubs. Deadheading hydrangeas not only helps maintain the plant’s overall appearance, but also encourages new growth and allows the plant to allocate its resources more efficiently. By removing the spent flowers, you are promoting a healthier and more vibrant bloom for the next season. So feel free to cut the brown hydrangeas without any worries, as it benefits the plant in the long run.
