Stopped cutting cedar flush and the tree told me why 8 months later
I used to be a flush cut guy on every removal, no exceptions, because it looked cleaner and I could knock it out faster. Last April I left about a foot of stub on a big cedar in a customer's yard in Boise just because my saw was buried and I was losing light. Went back in December to look at a different job and that stub had shrunk down to a nub and sealed over on its own with new wood rolling in around it. The flush cuts I did on two other trees in that same yard that spring were still open and dark, one of them was actually weeping down the trunk. I walked the whole block and saw the same thing over and over on the stubbed trees versus the flushed ones. It is not pretty but the tree clearly knows what to do with a stub and does not know what to do with a wound cut right into the branch collar. Anybody else leave stubs on purpose now, and how short do you go before it stops working?
