Should blueberry plants be watered during dry weather?
Blueberries have shallow, fibrous root systems. Plants quickly become stressed during hot, dry weather. To help retain moisture and control weeds, apply 2 to 4 inches of mulch around blueberry plants. Sawdust, wood chips, pine needles, and shredded leaves are excellent mulching materials. During dry weather, water plants every 7 to 10 days.
