A layer I did earlier in the year was checked for progress. As I worked the moss down I could see some good callus. Problem is I kept seeing more and more callus. Once it was fully opened up I could see that the entire layer area was fully engulfed in tissue and had reconnected. This full reconnection is what keeps a layer from issuing roots.
This view shows the huge growth of tissue bridging the gap. This is whare I made the cut for the upper portion. In hindsight I should have cut the lower cut lower, but that branch on the right is the part I wish to cut back to when I take the top off. That will be the leader for the bottom tree.
In this photo, one can just make out the two wraps of wire I put on the upper cut to keep this from happening. Looks like I need larger wire?
While I am still in the spring stage of growth, I will just clean up the growth and try again.
All of the tissue is cut away in the hopes that it will now sprout right away.
I will update here in a month or two to see if we do indeed have roots now.
