i bought a very slinder and tall hornbeam with a typical hedge tree form. My plan is now to chop the trunk off and the tree would lose ca. 2/3 of its foliage. As far as i know there are 3 different time frames for this work:
- Post-harden prune in around 2-3 weeks.
- After leave drop in the fall
- Before buds push in early spring next year
The more i think about it, the more confused i get. In my mind post-harden has the advantage of a faster callus forming and perhaps faster healing but more stress for the tree especially because of the huge loss of foliage. Pruning in the fall would be the least stress for the tree in my opinion but probably not the fastest healing process. Btw. the diameter of the trunk is ca. 2 inch (5cm). Chopping the trunk early spring next year is probably pretty similar to the post-harden prune but i would like to repot the tree already next spring so i would prefer one of the other options if possible.
What would you guys prefer? Post-harden chopping or chop the trunk in fall? And another side question: Would you anyway wait till next year and repot first and use the foliage mass for rebuilding the roots or first chopping and then repot?
Thanks again for your help.
