Critique from a city inspector saved me a huge headache

An arborist from the Parks Department said my pruning cuts were too flush to the trunk and showed me how leaving the branch collar intact prevents decay, and now I’ve changed our crew’s whole cutting method on every job-has anyone else had to correct their training on that?

Wait, aren't you supposed to leave the branch collar? That's what keeps the tree healthy. Flush cuts just invite rot and disease.

Exactly. The collar is non-negotiable for tree health.
