I have an apple tree that bloomed last fall because of the weird weather we had. We didn't do anything and the blooms never developed fruit. Now its blooming again. We didn't have weird weather like last year, in fact we're still in a drought and temps in the 85-90 range. What should I do? None of my other fruit trees are doing this. Oh and last year was the first time it bloomed, they were planted 4 years ago.
