Whats causing the leaves on my peach tree to thicken and curl?
This disease, called leaf curl, is caused by a fungus that affects peaches and nectarines. Infection occurs, when leaf buds begin to swell in early spring, by rain splashing the spores from infected bark onto the buds. Nothing can be done about it at this time. To prevent recurrence next year, spray your tree immediately after leaf drop in the fall with lime sulfur or chlorothalonil, (Daconil). Follow the manufacturer’s directions.
