This is the result of making a large pruning cut: decay.
Large pruning wounds can be difficult for trees to seal off and compartmentalize, increasing the opportunity for decay to develop and spread within the wood.
Whenever possible, avoid making large pruning cuts. Instead, focus on keeping pruning cuts small and making proper cuts while branches are still young and manageable.
Proper pruning isn’t just about shaping a tree. It’s about preserving its structure, health, and long-term condition.
Think ahead. Keep cuts small. Give your trees a better chance to thrive.
