How to Prune Hydrangeas in Fall
Hydrangeas are a beautiful addition to any garden, but in order to keep them healthy and blooming, they need to be pruned regularly. Fall is the perfect time to prune your hydrangeas, as it allows them to focus on root growth during the winter months. In this article, we'll go over everything you need to know about pruning hydrangeas in fall.
Why Prune Hydrangeas?
Pruning your hydrangeas is essential for maintaining their health and promoting new growth. When done correctly, pruning can help control the size of your hydrangeas, improve their shape, and encourage more blooms. It also helps remove dead or diseased wood, which can attract pests and disease.
However, it's important to note that not all hydrangeas require pruning. Some varieties, such as the Annabelle hydrangea, bloom on new wood and should be pruned in late winter or early spring. Be sure to identify what type of hydrangea you have before pruning.
When to Prune Hydrangeas
Fall is the best time to prune most types of hydrangeas, as they have finished blooming for the season and are entering dormancy. Pruning now will allow the plant to focus on root growth during the winter months, which will help promote healthy foliage and blooms next year.
If you're not able to prune your hydrangeas in the fall, you can also do so in late winter or early spring before the new growth begins. However, avoid pruning in the summer, as this can remove the buds that will produce next year's flowers.
How to Prune Hydrangeas
Before you begin pruning your hydrangeas, make sure you have the right tools. You'll need a pair of sharp pruning shears, and if your hydrangea is particularly large, a pruning saw may also be necessary.
Start by removing any dead or diseased wood, cutting it back to healthy wood. Next, look for any crossing branches that may rub against each other and cause damage. Remove these branches, cutting them back to where they meet another branch or the main trunk.
For most types of hydrangeas, you can also remove up to one-third of the oldest stems at ground level. This will prevent the plant from becoming too woody and encourage new growth.
When pruning mophead or lacecap hydrangeas, be careful not to remove any buds that will produce flowers in the coming year. These hydrangeas bloom on old wood, so removing too much can reduce or eliminate next year's blooms. To be safe, only remove the top portion of the stem, leaving a few buds below the cut.
Aftercare
After pruning your hydrangeas, be sure to clean your tools with rubbing alcohol or a bleach solution to prevent the spread of disease. You should also water your hydrangeas thoroughly and add a layer of mulch around the base of the plant to help retain moisture and regulate temperature.
If you live in an area with harsh winters, you may want to consider wrapping burlap around your hydrangeas to protect them from frost or snow damage. Just be sure to remove the burlap in the spring once the temperatures start to warm up.
Pruning your hydrangeas in the fall is an essential part of keeping them healthy and promoting new growth. By following these simple steps, you can help control the size and shape of your hydrangeas, remove dead or diseased wood, and encourage more blooms. Remember to identify what type of hydrangea you have before pruning, and always use sharp, clean tools for the job.
