Pruning · Question 12 of 25Random
When removing a branch, where should the final cut go?
AFlush with the trunkYour answerBJust outside the branch collarCorrectCHalfway along the stubDInside the branch bark ridge
AI TutorQuestion 12 · you chose A
Why not flush with the trunk? That leaves the neatest wound.A flush cut goes through the branch collar. The collar is where the trunk starts walling off the wound, so cutting it away leaves a bigger wound that closes worse and lets decay into the trunk.How do I find the collar on a real tree?Look for the swollen ring where the branch meets the trunk, and the branch bark ridge, the raised line of bark in the crotch. The final cut goes just outside both.And if the branch is heavy?Use three cuts. An undercut a little way out, a top cut further out so the weight drops, then the final cut outside the collar. That stops the bark tearing down the trunk.What should I remember for the exam?The final cut goes just outside the branch bark ridge and the collar. Answers that cut flush, cut inside the ridge or leave a stub are wrong.
