About Hydrangeas

Hydrangeas are popular flowering shrubs known for their large, showy blooms and attractive foliage. They come in various types, including mophead hydrangeas (Hydrangea macrophylla), lacecap hydrangeas (Hydrangea macrophylla), panicle hydrangeas (Hydrangea paniculata), and oakleaf hydrangeas (Hydrangea quercifolia). Each type has unique growth habits and flowering characteristics, which should be considered when pruning.

Detailed Guides

Understanding Hydrangea Types: Learn about the specific growth habits, bloom times, and pruning requirements of the hydrangea variety you have. Different hydrangeas bloom on old wood (previous year’s growth) or new wood (current season’s growth), and pruning at the wrong time can impact their flowering.

Pruning Mophead and Lacecap Hydrangeas: These hydrangeas bloom on old wood. Prune them right after flowering or in early spring before new growth begins. Remove dead or damaged branches and selectively thin out crowded stems to improve air circulation and shape the plant.

Pruning Panicle Hydrangeas: Panicle hydrangeas bloom on new wood. Prune them in late winter or early spring before new growth emerges. Cut back the stems to about 1/3 of their length to encourage vigorous growth and abundant blooms.

Pruning Oakleaf Hydrangeas: Oakleaf hydrangeas also bloom on old wood. Prune them after flowering or in early summer, allowing sufficient time for new buds to form. Remove dead or weak branches and shape the plant as desired.

General Pruning Tips: Use clean and sharp pruning tools to make precise cuts without causing unnecessary damage. Always prune above a healthy bud or leaf node and avoid cutting too close to the main stem. Maintain a balanced shape by removing overgrown or crossing branches.

Questions and Answers

Q: My hydrangea didn’t bloom this year. What could be the reason?

A: Lack of blooms in hydrangeas can be due to several factors, including improper pruning, extreme weather conditions, insufficient sunlight, or nutrient deficiencies. Review your pruning practices and ensure you are pruning at the correct time for your specific hydrangea variety.

Q: Can I prune my hydrangea to control its size?

A: Yes, you can prune hydrangeas to manage their size and shape. However, keep in mind that excessive pruning may reduce flowering in certain varieties. It’s best to follow the specific pruning guidelines for your hydrangea type to avoid negatively impacting bloom production.

Q: How can I rejuvenate an overgrown hydrangea?

A: If your hydrangea has become leggy or overgrown, you can perform a rejuvenation pruning. In late winter or early spring, cut back the entire plant to about 6-12 inches from the ground. This drastic pruning will stimulate new growth and result in a more compact and vigorous plant.


Pruning hydrangeas is a crucial task to maintain their health, shape, and abundant blooms. Understanding the specific pruning requirements of your hydrangea variety is key to successful pruning. By following the appropriate pruning techniques for each type of hydrangea and addressing their individual needs, you can enjoy a well-maintained and flourishing hydrangea garden that brings beauty and joy to your outdoor space.
