Gray spots on my Blushing Delight apples
My Stark Bros. dwarf apple trees actually fruited this year! One only put on 1 apple, and it was accidentally picked. The Blushing Delight put on 12 or 13, and they have almost all developed gray spots that look sort of like an appaloosa horse. Weird... I can't find anything about it. Any ideas? Fungus? Insects?
