I am late to do any work on my 20+ trees this winter, had other personal things I was busy with. So I just started. Did an English Elm and hornbeam over last few days. I would not think twice about pruning any of the 6 Chinese Elms I have.
True, I see it recommended to do earlier so they heal slightly but honestly, its meaningless... I am one for "ideal" timings but sometimes, things gotta be done and we have to remember that ideal or not, it can sometimes make little to no difference.
Only other thing I would say about pruning and this time of year is, I hear, don't do it too much near Spring. Yes they'll start to be active and heal but by Spring, the tree will have pushed those nutrients and "energy" up to its branches and buds... then we come along and cut them off... sure it'll heal but we are cutting off a lot of good "energy" in that process. id prefer not. Like to be able to sit back and enjoy Spring, watch the trees do their thing, no work... except repoting.... ah god, I have so much repotting to do, I just briefly forgot.
