Have your trees been outdoors getting lots of rain and high humidity? If yes, then you probably have peach leaf curl. There are two solutions. One is to grow the trees in pots and put them under shelter in the winter/wet months to avoid spreading the fungus on the leaves. I have some dwarf peach bushes that I grow in pots- they go in the greenhouse during the winter and come out in the late spring. The other solution, on outdoor planted trees, is to spray copper during the late winter. I use a OMRI (Organic Association) - approved organic version of this spray. Even though my trees are resistant, I live in rainy Oregon so I still have to spray copper anyway. Also, there are other folks on this website currently debating the merits of horsetail tea to prevent curl.
If your trees have no exposure to rain and high humidity, then you probably have a different problem. Do your pots have good drainage? Can you flip the pots over and peek at the roots? If the soil is too dry or too wet, that could be your problem. In this situation, I would just prune off the diseased/curly leaves and put the trees in well-drained pots in high- quality potting soil.
Finally, if you are in the US, I could send you some Indian Blood peach seeds. This variety has good resistance and is one the most delicious fruits in existence. There is an excellent thread on here about this variety and how people grow them from seeds. Please send me a private message if you are in the US and want peach seeds. Good luck!
