Before you start pruning your hydrangeas, it's important to know when to do it. Generally speaking, the best time to prune hydrangeas depends on the type of hydrangea you have.

Determining the type of hydrangea you have

There are several different types of hydrangeas, each with its own unique pruning needs. The most common types of hydrangeas are:

Panicle hydrangeas

Panicle hydrangeas bloom on new wood, so they can be pruned in the late winter or early spring. To encourage fuller growth, you can cut back up to one-third of the plant's height.

Smooth hydrangeas

Smooth hydrangeas should be pruned in the late winter or early spring before new growth begins. These hydrangeas bloom on new wood, so they can be pruned more heavily without worrying about cutting off next year's blooms.

Oakleaf hydrangeas
