I have heard that it is wrong / unethical to cut burls off of live, healthy trees. This makes perfect sense, as it is an injury to the tree. But does it cause more injury than a regular pruning cut ? On some burls the attachment point is relatively small and it would seem that it would compartmentalize fairly quick as compared to burls with very wide attachment point(s) ??? Also, since most burls are on the trunkwood, it may be more injurious ??? My sister has a patch of woods on the back of her property and I spied a nice maple burl. Angel on one shoulder saying, "Sweet. Now leave it." Voice from the dark side saying, "Sweet. Take it. It won't really hurt anything." Input ? Thanx
