What’s the best time of year to prune a birch tree?

The best time to prune a birch tree is during its dormant season, which is typically between late fall and early spring. This is when the tree is not actively growing and will be less likely to experience stress or damage from pruning. Late winter or early spring, before the tree starts to bud, is often considered the best time for pruning birch trees, as it allows for easy identification of dead or diseased branches and encourages new growth. It is important to avoid pruning birch trees during periods of active growth in the summer, as this can disrupt the tree's natural processes and make it more susceptible to disease or pest problems.
