Answer: Flowering trees and shrubs should be pruned immediately after they have finished flowering. Those that do not flower can be pruned in March, just as new growth begins. It's true that landscapers seem to prune at any time of the year, even in the heat of summer, but I don't think that's a healthy practice! Prune in the spring or immediately after flowering has finished and your trees and shrubs should thrive. Enjoy your garden!
