Pruning shrubs and trees is better left to late winter. It means fresh wounds only spend a short time exposed to the elements before new growth begins and the wound heals. Pruning during the winter also allows you to prune shrubs without leaves blocking your view of the branches underneath. Pruning involves selectively cutting certain branches from trees and shrubs as a preventative measure to produce desired growth patterns and healthier plants. Pruning time depends upon how many shrubs you have to prune, and requires attention to detail to ensure all shrubs are properly pruned.
Prune one section of a row of shrubs. Working your way in one direction, ensure you do not accidentally pass over a shrub that needs pruning. You also want to start on one side or area of the shrub to make sure you cover the entire shrub.
