When is the best time of year to prune/trim trees?
Pruning may be done any time of the year, but some times of year are better than others. Deciduous trees that flower before the end of May should be pruned right after blooming. Deciduous trees that flower after May should be pruned between January and March. Prune flowering Cherry trees in late summer, flowering Evergreens in May, and Conifers in Autumn. Remove dead, damaged, or diseased wood as soon as it is discovered.
