major pruning of plum tree - advice needed
My plum tree has fruited heavily this year, and (even though I thinned the fruit following advice on here) in the last spell of wet and windy weather a couple of the major branches (and several more minor ones) bent right over and nearly snapped, so they're now hanging vertically down. I left them on to see if the fruit would ripen, and it has. But now as we enter the second half of August I am thinking I really need to sort the tree out, sacrificing any remaining fruit if necessary.
So I'm after major pruning/cutting back advice. A couple of the branches which need cutting off are approx 1-1.5 inches thick. And several smaller ones, of 1/2 to 1 inch.
I know about the desireability of pruning in summer to avoid silver leaf. Should I wait until we have a couple of dry days forecast before removing the branches, to give them a chance to heal before it rains? (Will that make any difference?) Or is there something I can put on the raw cut ends to protect them?
