Are they dwarfs or semi dwarfs?

I'm jealous my container citrus doesnt look anywhere as nice. But I'm indoor with an pesticide accident that hurt the leaves.

May I ask what you fertilize them with?

Jobes organic citris, little espom salt, and a little nitrogen (bone meal). When I think they are tired of the same I give light miracle grow instead. Most times I don't know what I am doing, however this seemed to work for me. I use a little of the above e together. No measurement.

Your peach tree may well have something called peach leaf curl. Google it for photos that you can compare to and to find suggested treatment.
