Keeping apples on the tree during growing season
I have an apple tree that my Grandfather grafted about 40 some years ago. I think one of the trees he used was called Early Yellow Harvest. My Mom thinks me other part of the graft was was Striped Astrigen. The problem is, the apples never stay on the tree through the growing season. Once they begin to grow, they start falling off all summer long. They don't stay on the tree to grow and ripen. Is there anything I can do to keep the apples on the tree until they are ready to be picked? I haven't pruned the tree and also need to deal with worms/insects in the fruit. I know when I tackle the worm/insect issue next year I want to keep it all natural. It's just very frustrating because there is so much fruit in the tree this year but it's falling off before it's ripened. Any ideas what's to do?
