In February this year when I checked the grafts made in May, 2016, I came across the graft shown in the following picture:
The scion had only produced a couple of leaves during last Summer and it was less than two inches long – the prognosis did not appear to be good. Although in the picture above it appears that the scion wood had actually died, using a pruner to snip off the end of the scion revealed green cambium. So, instead of giving up on the graft, I decided to wait and see what would happen this Spring.
The following picture was taken in late July of this year and shows how the short piece of scion wood has expanded in girth and popped a bud with a strong limb. Note that the bark has still not grown over the staples. But, this years growth is impressive.
And, here is a picture showing the top of the tree which has added about three feet of new growth this year.
It is interesting to note that the variety of scion wood in this graft is Kanza. In my experience trees of the Kanza pecan variety seem to have a will to live that exceeds that of other pecan varieties.
