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
Did you *cut* at the collar or do you mean you left a stub?
A fork is where it *should* be cut; a mid-branch will never heal.
Unfortunately, most people - including pros - butcher trees when they trim.
When cutting, you need to determine the location of the "collar" between
limb and trunk. That location can be difficult to spot sometimes, depending
on type of tree, but it is where the bark direction changes from vertical on
the trunk to sideways at the limb. You need to cut just above the collar so
that the cambium layer from the trunk can overgrow the cut. Here's a link
to a photo (red = collar, blue = cut line)...
and to the article.
Thanks for the post and the picture link.
That pretty much is where I cut. I may sharpen the angle a little after I
clear the mess and really study it. My branch was more vertical and that
was the confusing part. The limb had to go no matter what the eventual
outcome. Would have been better for the tree if I had done it years ago.
