Hello all. I have a Rock Cotoneaster in my yard i planted years ago, and i was thinking about doing some pruning on it to see how it might grow as an upright tree. It does come out as a single trunk, but only for about an inch or two, then just dozens of branches going everywhere. Should i chop back all the other tangled branches to one going in a good direction for the second secion of the trunk? or is this typeof tree mostly worked from when it is young? Just curious if they chop easily or should i just leave it in the landscape? Thanks for any input.
