What to look for

Look where the branch meets its parent stem for the slightly swollen branch collar. Do not confuse it with the trunk or neighboring growth; larger branches and overhead work can require a professional.

What to do

For a small, accessible branch, cut just outside the collar without cutting flush into the trunk or leaving a long stub. If the collar or safe cutting position is unclear, leave it and seek plant-specific advice.
