Whats the best time of year to prune my trees and shrubs?
Most trees and shrubs can be trimmed and thinned anytime during the growing season. Heavy pruning, if needed, should be performed during the cooler days of fall and early spring. Spring flowering shrubs such as lilac and forsythia should be pruned after to ensure a good flower the following season. To reduce frost damage, roses should not be pruned hard until the month of March.
