When Do You Prune Hydrangeas? A Complete Guide

Introduction
Pruning hydrangeas is a vital part of maintaining their health, shape, and ability to produce stunning blooms. However, the timing of pruning depends on the type of hydrangea you have, as some bloom on old wood and others on new wood. This guide will help you determine when to prune hydrangeas based on their type and provide tips for proper pruning to ensure vibrant flowers and healthy growth year after year.

Why Pruning Hydrangeas Is Important

Pruning hydrangeas helps in several key ways:

• Encourages New Growth: Stimulates fresh, healthy stems.
• Maximizes Blooms: Promotes more abundant and vibrant flowers.
• Maintains Shape: Prevents overgrowth and keeps the plant neat.
• Prevents Disease: Removes dead or weak stems that can harbor pests and infections.

When to Prune Hydrangeas

The right time to prune hydrangeas depends on whether they bloom on old wood (growth from the previous year) or new wood (growth from the current year).

1. Old Wood Bloomers (Hydrangea macrophylla, Hydrangea anomala subsp. petiolaris)

• Examples: Mophead, lacecap, and climbing hydrangeas.
• Best Time: Late summer or early autumn, after flowering.
• Why: These hydrangeas set their flower buds for the next season on old wood. Pruning after flowering gives the plant time to develop buds for the following year.
• Tips:
  • Remove spent blooms (deadheading).
  • Trim lightly to maintain shape without cutting into live buds.
  • Remove dead or damaged stems.

2. New Wood Bloomers (Hydrangea paniculata, Hydrangea arborescens)

• Examples: Panicle and smooth hydrangeas.
• Best Time: Late winter or early spring, before new growth starts.
• Why: These hydrangeas bloom on new wood, so pruning during dormancy encourages fresh, vigorous growth and abundant flowers.
• Tips:
  • Cut stems back to 30–50 cm above the ground.
  • Remove any weak or crossing stems to improve structure.

3. Re-Blooming Hydrangeas (Endless Summer Hydrangeas)

• Best Time: Light pruning after flowering and heavier pruning in early spring.
• Why: These hydrangeas bloom on both old and new wood, providing more flexibility in pruning.
• Tips:
  • Deadhead spent blooms to encourage additional flowers.
  • Prune to shape and remove winter damage in early spring.

How to Prune Hydrangeas

Step 1: Identify Your Hydrangea Type

Knowing whether your hydrangea blooms on old or new wood is essential for pruning correctly.
