Introduction
Hydrangeas are some of the most popular flowering shrubs, and for good reason—they offer a wide variety of colors and shapes, and can be enjoyed in almost any garden. Pruning is an integral part of keeping these plants healthy, and can mean the difference between a thriving garden and a struggling one. In this article, we'll take a look at when and how to prune hydrangeas.
When to Prune Hydrangeas
When it comes to pruning, timing is everything. Pruning hydrangeas at the wrong time of year can cause them to bloom poorly, and in some cases, not at all. For most types of hydrangeas, the best time to prune is in late winter or early spring, before they start to bud. This is the time when they are dormant and won’t be affected by your pruning. To be safe, wait until after the last frost of the season before pruning.
If you have a reblooming variety of hydrangea, such as a ‘PeeGee’ or ‘Endless Summer’, you should wait until after the first flush of blooms to prune. These varieties bloom on old and new wood, so pruning too early will reduce the number of blooms you’ll get.
How to Prune Hydrangeas
When it comes to pruning, the most important principle is to remove only dead or damaged branches, as well as any branches that are growing too close together. You should also remove any branches that are crossing or rubbing against each other, as these can lead to damage. For the most part, hydrangeas are easy to prune, and don’t require any special techniques or tools.
Start by looking for any dead or damaged branches, and remove them with pruning shears or a pruning saw. Next, look for any branches that are growing too close together, or that are crossing or rubbing against each other. Remove these branches as well. Then, look for any branches that are growing in the wrong direction, and prune them back to a more desirable shape. Finally, if you want to keep your hydrangea at a certain size or shape, you can trim the ends of the branches back to the desired length.
Pruning Tips
When pruning, it’s important to use sharp, clean tools. Dull tools can tear the bark, which can lead to damage and disease. It’s also important to prune in the right places. For most hydrangeas, it’s best to prune just above a node on the branch, as this is where new growth will occur. You should also avoid pruning too much, as this can lead to a decrease in flowering.
Another important tip is to avoid pruning in late summer or fall. Pruning at this time can encourage new growth, which may not have time to harden off before the cold weather arrives. This can lead to winter damage, and can even kill the plant.
Conclusion
Pruning hydrangeas is an important part of keeping them healthy and looking their best. Pruning at the right time of year, using sharp, clean tools, and avoiding over-pruning can help ensure your plants look their best. With the right timing and techniques, you can keep your hydrangeas blooming and looking great for years to come.
