Dear Terri,

Thank you for contacting us. I cannot be sure from the photos, but it looks as though your tree may have a fungal disease known as peach leaf curl. I suggest you take a sample to your county Extension office for closer inspection.

The best defense against this disease is to plant cultivars that are resistant to the disease. It is possible to spray with fungicides, but this must be done in late autumn and again just before flowering. Good garden sanitation is also important, so try to rake up any fallen leaves or debris and place them in the trash (not the compost).
