Cultural Management Practices for Blueberry Plantings

Pruning twig dieback. Cut out any twigs that appear to be weak or begin to die; make cuts several inches below the affected area. Twigs heavily encrusted with scale insects should be removed and destroyed early in the spring before the buds start opening. 

Sanitation. Collect and remove any mummified fruits from under blueberry bushes by thoroughly raking the area in early spring before the buds break. This practice can effectively control mummy berry disease without the use of fungicides.
