My trees are nearly all young enough that if a few years were missed in regards to pruning, it would mean very little. The few large mature trees can all be pruned in a relatively short period of time. That being said, we have put in a few hundred trees and in the future this will not be the case. I have been told in the past, that as a general rule you do not prune trees when expecting temps to fall close to 0 before it warms up again. This week is the first time this winter where the extended forecast no longer shows that to be the case going forward. Do any of you have experience with cold damage caused by pruning when cold weather follows, and how detrimental is it for the tree's longevity and ability to resist disease?
