The best time to prune blueberry bushes is in late winter or early spring, just before new growth begins. Pruning while the plant is dormant minimizes stress and encourages vigorous growth and fruit production.
How to Prune Blueberries Remove any dead, damaged or diseased wood first. Cut these branches back to healthy wood or the ground.
Thin out the center of the bush to allow light and air circulation. Remove any low-growing, weak or twiggy branches.
Prune out any branches that are crossing or rubbing against each other. This prevents damage and disease.
For mature bushes over 6 years old, remove 1-2 of the oldest, thickest canes (over 1 inch diameter) at ground level each year. This encourages new, productive growth from the base.
Aim to maintain 6-8 main canes of varying ages for the most fruit. Prune out any extra canes at the base.
Make clean cuts just above an outward-facing bud or branch. Angle the cut slightly away from the bud.
