BTW, i did a search for this and did find stuff on peach leaf curl, but there were no basic instructions on what to do. I don't have an orchard, just one sad little tree. I need basic help..:(

Too late for this year. You have to either fungicide in fall or early spring before the leaves come out. Any leaves that you see changing colors right now got infected while the buds were breaking, and having fungicide on the surface of the leaves isn't going to do a darn thing to get rid of the infection inside them.

Don't worry too much about it; it's not typically lethal. It'll make your tree waste energy, though, so you might want to thin the fruit and make sure they have plenty of water.

How did your tree die last time?
