If you grow blueberries and found shriveled gray fruit mixed in with normal plump berries your bush is infected with “Mummy Berry” disease. To lessen the severity of the disease in next year’s crop, gather all the mummy berries you can find and throw them away. Add mulch in autumn to cover up the infected mummies that fell to the ground, and then cultivate around the bush in early spring to disrupt the fungal life-cycle that starts in the soil. Details and color pictures.
