So another winter has passed and it's another winter I've had nearly 100% die back of the top of my trees. As I see it the problem is two-fold.
- Green Trees + Freeze = Nothing good. Being that I am on the border of zones 8b/9, my trees remain green well into November. This year, the coolest day before our first freeze was about 65F. Consequently, the tree is w/leaf when the freeze hits. This year, my trees pushed new growth between freezes.
- Wind. I'm not sure my trees freeze so much as they dry out. Just about all times of the year, the wind blows pretty good.
As I was pruning off the death off my trees and thinking of how best to protect my trees, I had an idea. Grow multi-trunked trees low to the ground (or a single-trunk with scaffolding branches starting @ 2') and pollard the end of the limbs. The advantage being the base of the tree would become more hardy as it ages and the remainder of the tree would be pruned back to the pollard head before the first hard freeze. Also, the tree would be easier to cover and uncover as needed.
Does anybody have thoughts on this before I try to affect it?
Thanks in advance,
