It probably makes sense that trees and shrubs go dormant about now, especially the ones that shed their leaves. This makes the period starting November 1 ideal for pruning. We can clearly see the structure of the plant, especially any crossing branches or water sprout type growth that may have emerged this season. Densely twiggy plants such as bridal veil spiraea are much easier to prune now. Maples and Stewartias that have heavy sap production in spring are best pruned in late fall to avoid this problem.
