Protect Your Plants This Winter: Pruning Tips That Ensure Healthy Regrowth
Experts advise removing dead or diseased branches first and following the one-third rule to protect plant health during winter pruning.
Winter is considered one of the best times to prune many trees and shrubs, as plants are dormant and less prone to stress or disease. However, improper pruning can cause lasting damage. Experts recommend a methodical approach to ensure healthy regrowth in spring.
Evergreen shrubs are best pruned soon after they have finished flowering. Hard pruning of evergreens can usually be done in late winter or early spring, but as always, look the plant up first to check on pruning requirements.
Start with planning and preparation
Before pruning, gather clean, sharp tools such as secateurs and loppers. Sterilise blades with rubbing alcohol or a bleach solution to prevent the spread of diseases. Follow the one-third rule—never remove more than one-third of a plant’s total growth during a single pruning session. Begin by cutting away any dead, broken, or diseased branches. These should be removed completely back to the main branch or healthy stem.
Pruning small and large branches
For smaller branches, make a clean cut about a quarter-inch above an outward-facing bud at a 45-degree angle. This encourages new growth to develop away from the centre of the plant, improving air circulation. Avoid leaving stubs, as they can rot and invite disease.
For larger branches more than 2 inches thick, use the three-cut method to prevent bark tearing. First, make an undercut about a foot away from the trunk, cutting one-third into the branch. Next, make a second cut farther out to remove the branch’s weight. Finally, make a clean cut just outside the branch collar to allow the wound to heal naturally.
Shaping, maintenance and clean-up
After removing problem branches, use thinning cuts to shape the plant and allow more light and air to reach the centre of the canopy. This involves removing entire branches from their base rather than shortening them. Once pruning is complete, collect and dispose of all cut branches and leaves. Diseased material should not be composted near the garden.
A layer of mulch can be applied around the base of the plant to retain moisture and support soil health. Ensure the mulch does not touch the stem or trunk directly.
Winter pruning, when done correctly, promotes vigorous growth, prevents disease and enhances plant structure for the coming seasons.
