Maintenance pruning on pear trees
I have a couple of pear trees that are about 20 years old. I pruned them heavily at the beginning of March. They were a mess--I'm not sure they had ever been pruned before. I took a lot of branches off. Anyway, they look much better.
I've noticed that, now that the trees have leafed and fruited out, one of the branches is drooping down pretty severely. I thinned off some of the new pears, but it's still hanging down. Should I just let it hang down, or cut off part of the branch?
I've also noticed a lot of new shoots that are growing straight up. Can I pinch these off, or should I avoid all pruning when the tree is not dormant? I've noticed many small dead, black branches too (probably from the drought we've been having). Is it OK to remove these at any time?
Thanks for any info.
