Hi Jan,
All I can say is WOW! ...Very nice trunk and great recovery response. I think it might be a bit early to decide on styling choices...but one can dream I suppose
Great find...give it a chance to rest and recoup and you'll have some stonker material in no time at all
I didn't see Toms response until after I read, and looked at your photos, and Tom said it very well Wow, nice find Jan.
I realize that hawthorn has about a gazillion varietys, but is defoliating something that works with these in general, or is it limited to certain species, or even to the European local??
Those things just attract the rust don't they, although I have to say that I have only had to remove a few leaves last year, this year so far I have stayed clean.
Here is one I have in training(not a great photo, but you get the idea), not nearly so impressive as yours Jan, but I am liking it so far. Do you clip the needles, and do you realize that by doing so you get some budding as well? Yes the grow box is an old kitchen cabinet drawer
