I have 4 established Dogwoods in different areas of my yard, these trees are between 40 and 50 years old each. To my knowledge, they have never been pruned and they need some attention. They have some old dead branches that need to be taken off, and of course some small sucker limbs that are growing out of the trunks down low, and in the way of mowing around them. One of the 4 of them is diseased, and the bark on this particular one is flaking off in sheets, and the actual inner wood is exposed and has a very "dry" and dead look to it, even though it is still barely alive. I know that this one is on its last leg, and has to be cut down. My question is this, I live in N.C. and these trees have already bloomed of course, and now we are heading into the middle of Summer. Would it be best for me to wait until the sap drops in Jan. or Feb. when it's cold to prune these trees, and give them a little fertilizer, because of the possibility of bugs getting into the pruned limbs? Or does it make any difference about pruning Dogwoods? I have heard it both ways, please tell me what you think. I want to save these remaining 3 beautiful old trees, I know the 4th one will have to go.
Thanks for any advice
