I live in Northeastern Pennsylvania, a cold Zone 5, and have an orchard
of apple trees. In the past, I've pruned the trees in mid to late
February when they were in full dormancy, however, this year I sprained
my ankle and won't be able to get to them until late March. Is this
still ample time for pruning? What would be the absolute last day to
do so? Thank you for your help.
