When to Prune Your Shrubs: Timing and Safety Tips for Healthy Growth

Pruning your shrubs at the right time keeps them healthy, attractive, and safe around your property. As your partner in landscape care, we want you to understand the basics of shrub pruning so you can maintain your outdoor spaces between our professional visits.

Timing is Everything

The best time to prune most shrubs is late winter or early spring, just before new growth begins. This timing allows the plant to heal quickly and directs energy toward fresh, vigorous growth. For spring-flowering shrubs like lilacs and forsythias, wait until after they bloom before pruning—otherwise, you'll remove next year's flower buds.

Summer is generally not ideal for heavy pruning, as heat stress combined with pruning wounds can harm your plants. Fall pruning can stimulate tender new growth that frost may damage.

How Much Should You Remove?

A safe rule: never remove more than one-third of a shrub's total volume in a single season. This means cutting back no more than one-third of the branches. Removing too much at once shocks the plant, weakens its structure, and leaves it vulnerable to disease and pest damage.

For overgrown shrubs that need significant reduction, plan for multiple years of gradual pruning. Remove the oldest, thickest branches first, cutting them at the base. This encourages younger, healthier stems to take over.

Technique Matters

Always use sharp, clean pruning tools to make clean cuts. Dull tools crush stems instead of cutting them, leaving wounds that invite disease. Make cuts just above an outward-facing bud at a slight angle to shed water.

Never leave stubs protruding from the shrub—these die back and become entry points for pests. At the same time, don't cut too close to the bud, which can damage it.

Know Your Shrubs

Different shrubs have different needs. Evergreens like boxwoods tolerate pruning well and can handle formal shaping. Deciduous flowering shrubs need more gentle care timed around their bloom cycles. If you're uncertain about a particular shrub, our team can assess its specific needs.
