Rule of thumb is when trees and shrubs go into dormancy, they can safely be pruned. Pruning can continue until you see buds start to round out and plump up. For Chicagoans, this usually means that pruning can safely happen between mid-November to mid-March. The only exception to this is evergreen trees. These trees really should be pruned during their growing season. Evergreens never become fully dormant and because of this they can suffer tip burn if pruned in the winter.
Why prune? So, now, why would one want to prune is some of the coldest, most brutal months of the year?
1. Trees without leaves are much easier to prune because you can easily see the branch structure.
2. You minimize the risk of transmitting diseases from one plant to another.
