Hello (and happy new year!) After a very nice Autumn where I've been able to really appreciate all the fall colors this year, I was wondering if I should start doing a bit of maintenance one some trees. Since all the leaves have gone, I can now clearly see all the diebacks on some branches (see photos as examples) I've got two questions 1/ Is it a good time to cut die back, or it's better to wait for early spring? 2/ When cutting the die back, is it better to cut down to an area non black/dead just above buds? If I cut these now, wouldn't the twig die further down? Where and when would it be best to cut? thank you!
