I'm a big fan of Avalon Pride which is leaf curl resistant, and delicious. I got mine at raintree nursery.

Thanks! I will go look it up. Anymore suggestions will be well takenQ

Hi -- I live on Bainbridge Is. and have had great success with Hardired Nectarine from Raintree Nursery. The fruit is delicious, and it is a pretty tree. Snow peaches have less problem with leaf curl, so I think that's why people plant them around here, but the fruit is insipid as far as I'm concerned. Leaf curl is just gross, and I've sprayed and picked off affected leaves, and last year with the wet spring, I gave up on the crop and did a major pruning from which the tree recovered magnificently. I'm about to spray for the first time with Lime Sulfur as a dormant spray, but using such a big gun has me a little nervous. If it keeps the disease at bay, it will be worth it.
If you want flavor, I think you'll have to fight the Curl!

Another method is to espalier against south-facing wall, beneath awning or overhang.

I've created a list of all of the peach leaf curl resistant trees that I've planted and their nursery suppliers. A few have started to produce, and most seem promising in Seattle area.

My Hardired nectarine had leaf curl badly. ( Seattle area)

Sounds interesting, how old is yours and is there a dwarf? Where did you find it? Thx
