Step 1 When to Prune Your Trees and Shrubs
Many common shade trees can be maintained at any time of the year, however, it is recommended to avoid any major pruning from January through early March.
The consensus for the best time to prune trees is late fall to early winter, during which, trees tend to shed their leaves. This allows for the structure of the tree to be clearly visible for effective pruning.
