I think I have a codling moth problem on my 10-15 year old apple tree. There are apples falling prematurely and they have holes with something brown filled in them. The tree is fairly large (it hasn't been pruned in a few years) and it looks like many apples on the tree have the spots/holes, too. Is there any way to stop this problem for this season or for future seasons? I would rather not spray insecticides if I had a choice.
Thank you!
