This Peach Tree has leaf curl disease and did not produce any fruit this past season after years of delicious fruit every season. It seemed like it was about to drop it's leaves and I was planning on spraying it w/ fungicide once it did. However, I was gone for a couple weeks and just returned to find it full of new leaves!

Also~ When I pruned it during dormancy last season, I trimmed off several new growth branches but made sure to leave a few of them. I have not fertilized since the flowers first appeared a few months back when I used foxfarm bloom.

So I guess my question is, what going on with the tree and when should I spray fungicide? Do I have to wait for the leaves to drop?
