This tree sat. ...and sat. ...and sat some more. It hasn't done ANYTHING after leafing out initially ...as you might expect after seeing the drastic root reduction. I noticed this week that its beginning to put out new growth, mostly at the extremities right now, but I hope to get some good budding elsewhere. Eventually it'll have to be chopped so if I don't get the budding I want now, I'll probably get it then.
As for the root grafts, I have nothing to say. Since it sulked so obviously and for so long, I opted not to harass it by prodding around to see how the grafts were doing. I'll have to be patient until late-winter to find that out. By extension, so will you.
