I had to take a slightly larger limb than I prefer to cut off a tree in my yard today. A six inch limb at a major fork. If it was not at a fork I would not be concerned. The tree is fairly young, planted 15 years ago as
1.5" caliper. Some named variety of Honey Locust.I left a nice collar but I wonder if I might not be better off to make it a bit smaller so it can heal better.
If anyone in this group has knowledge about this topic I will post some pics with links.
