I have several (12) white oak trees in my yard that are 50 years or older in age. When is the best time to prune as the trees are lovely and I don't want to damage them. Thanks Tim Curran |
First, ask yourself why you need to prune them. As a rule, we tend to overprune. Mature trees usually require pruning only of dead, diseased, weak or crossed branches that might be a safety hazard. Prune when dormant, in late winter/early spring before new growth starts. |
