Thanks. The root grafts are growing well and are about 5 feet tall now. Hoping for some major thickening and fusion this season!
I did lose a minor branch over the winter (on the left) due to not doing a great job of apex parity. On curly willows, you have to make sure the foliage of all branches is at equal height, because they will drop branches that are getting shaded out like that one was.
But I think it's an improvement anyway because it was thinner than the other branches despite being lower on the tree.
