Take those mushy ones off and when the sun passes over mix 1 teasp liquid non alcohol soap w 1 qt water and spray the good ones......after the berries are done you can spray them in the fall to late fall with dormant oil.............also in the spring until the buds come on them. Wear old long clothes, mask, gloves, hat & goggles....don't spray if it is windy or going to rain. You also can ring the plant with lime to sweeten the ground.
