Annual Pruning Guide


Learn when is the best time to prune different types of trees and shrubs.


Here are some general guidelines on pruning:

Remove dead wood

Cut back to where the dead branch joins the stem.

Remove diseased and damaged wood

Branches that are badly diseased or cankered, or any that have been broken by wind or snow, should be removed.

Remove weak and overcrowded wood

Remove very thin and weak stems. If the branches are tighly packed at the centre of the plant consider removing some old wood to improve appearance and vigour.

Remove suckers

If the plant is grafted remove suckers growing from below the graft. Some non-grafted shrubs also produce suckers from the rootstock that should be removed.

Remove overgrowth

Remove awkwardly placed or problematic branches (eg. overhanging a path). This should be tackled every year and not left until it is a significant task.
