What can a person use to get rid of peach curl? In the ground and on the leaves? Any
Home remedies?

I've had that problem, as well. A form of prevention begins in the fall, but before frost. Spray the trees with a dormant spray. Then in the spring, spray again before the tree buds open. I learned from an orchard owner the next step is to spray, after peaches set on, each week with a fungicide. That's the short of it. You may want to take a look at www.jerrybaker.com and contact your state/county extension office. Hope this helps.

The best fix that I have found for peach leaf curl that I have found is a fall application of sprayable copper sulfate after the leaves have fallen. Apply to tree and ground surrounding the tree to get at the fallen leaves, then apply this same spray in early spring BEFORE the green tipped buds open. Do NOT spray after buds open and leaves appear as it will damage the foliage. Copper sulfate is approved for organic produce when applied as directed by the manufacturer. Peach leaf curl is fungal disease that overwinters in the fallen leaves and becomes active in the spring. I have found that it must be controlled in the fall and early spring as once it has made its way into the leaves I have never been able to reverse the damage. On the bright side, the tree will usually survive quite well as long as it is not severely defolliated, but each year the strike will be worse if left untreated.
Good luck Jim
