How to: Pruning Hydrangea

Hydrangeas add beautiful lushness and color to any garden or balcony. But how do you ensure the proper pruning of this floral beauty? Here we offer practical insights for pruning hydrangeas so you can preserve their beauty to the fullest.

Pruning Timing and Species:

It is very important to prune hydrangeas properly to maintain health and bloom. The most appropriate time for this is in early spring, in February – March, just before new growth begins. However, each type of hydrangea requires specific pruning methods. In many hydrangeas, removing spent flowers is sufficient to encourage the plant to produce new flowers. Some species, however, also require pruning away older branches to make room for new ones. There are hydrangeas that bloom on annual or biennial wood. A separate case is the climbing hydrangea, which requires special handling.

Pruning Methods by Species:

When pruning hydrangeas, the species is decisive. Here we discuss the main hydrangeas in the Netherlands and how best to prune them. Important is to use sharp secateurs and cut just above a bud.

• Large-leaved hydrangea (Hydrangea macrophylla): This biennial variety, also known as “peasant hydrangea,” blooms on branches from the previous year. Do not prune in spring, but cut old branches to the ground in spring, if necessary. Remove spent flowers after flowering and some older branches if desired to make room for new growth.
• Plumed Hydrangea (Hydrangea paniculata): This annual species blooms in summer to fall with large panicles of various colors. Prune the branches back to about 20-30 cm above the ground for a fuller plant and more flowers. Pruning is not necessary, however, and young plants do not even need to be pruned at all for the first two years.
• Annabelle (Hydrangea arborescens): This hydrangea blooms on young wood and can be pruned back to 15-30 cm above the ground each year. This will make the plant fuller and produce more flowers. If desired, remove older branches for new growth.
• Climbing Hydrangea (Hydrangea petiolaris): Prune this climbing plant in August or September, but not too rigorously. It flowers on shoots from the previous year. Prune back the branches that had flowers on them.

In conclusion:

Pruning hydrangeas requires some knowledge of the species. By taking the right approach, you can keep these beautiful plants healthy and enjoy their stunning floral displays in your outdoor space. Do you have questions about pruning? Feel free to send us a quick note and we’ll take a look with you.
