I am a novice and have a dozen or more old and big (20' approx) apple and pear trees that I would like to make as productive as possible. They all produce lots of fruit but most of it is very wormy. The deer are their main consumers. I was wondering if proper pruning would in any way make the trees have less wormy fruit. Or would I be just as well off to leave them alone? We pick a few bags of fruit that have avoided the worms and leave the rest to the deer. I'd like to increase the amount of good fruit but never at the expense of using chemicals. I am happy to put in the work of pruning but don't use chemicals. Any help would be appreciated. Thanks in advance to any one who wishes to take the time to advise me. jeep
