When to prune your trees and shrubs

Although trees and shrubs can grow very well without intervention, occasional pruning helps promote optimal health. Here’s what you need to know.

Flowering
Shrubs like rhododendrons and lilacs bloom from last year’s stems, whereas others, like roses and hydrangeas, bloom from new growth. It’s best to prune shrubs that flower from old wood immediately after blooming. However, shrubs that bloom on new growth should be trimmed in the spring.

Dormancy
In general, shrubs and trees go dormant in the spring before their buds open. This is the best time for pruning because the plants heal faster. Late fall is also appropriate. However, pruning in the winter should be avoided.

Furthermore, mid-summer is ideal for pruning trees that produce a lot of sap in the spring, like maple, birch, and willow.

Lastly, pruning large trees and fruit trees should be left to the experts. For the best results, contact a professional tree pruner in your area.
