Pruning Hydrangeas: Why and When?

Hydrangeas are a popular choice for gardeners due to their large, showy flowers that come in a variety of colors. However, to keep your hydrangeas healthy and blooming at their best, it is important to prune them regularly. Pruning removes dead or diseased branches, encourages new growth, and helps to control the size and shape of the plant. The best time to prune hydrangeas is in late winter or early spring, before new growth begins.

How to Prune Hydrangeas

The type of hydrangea you have will determine how you prune it. There are two main types of hydrangeas: those that bloom on old wood and those that bloom on new wood. * Hydrangeas that bloom on old wood should be pruned lightly, if at all. The flower buds for the following year are formed on the previous season's growth. Pruning these hydrangeas too heavily can remove the flower buds and reduce flowering. * Hydrangeas that bloom on new wood can be pruned more heavily. The flower buds for the current year are formed on the new growth. Pruning these hydrangeas encourages new growth and flowering. To prune hydrangeas, simply remove any dead or diseased branches. You can also remove any branches that are crossing or rubbing against each other. For hydrangeas that bloom on old wood, lightly prune the tips of the branches to encourage new growth. For hydrangeas that bloom on new wood, you can cut back the branches by one-third to one-half their length.

Benefits of Pruning Hydrangeas

Pruning hydrangeas has a number of benefits, including: * Increased flowering: Pruning removes dead or diseased branches and encourages new growth, which can lead to more flowers. * Improved plant health: Pruning removes diseased branches and helps to improve air circulation around the plant, which can reduce the risk of disease. * Controlled size and shape: Pruning can be used to control the size and shape of your hydrangeas. This is especially important if you have limited space in your garden.

Tips for Pruning Hydrangeas

Here are a few tips for pruning hydrangeas: * Use sharp, clean pruning shears. * Make clean cuts at a 45-degree angle. * Remove any suckers or water sprouts that grow from the base of the plant. * Fertilize your hydrangeas after pruning to help them recover. * Water your hydrangeas regularly, especially after pruning. By following these tips, you can keep your hydrangeas healthy and blooming at their best for many years to come.
