Should I water my raspberries during dry weather?
Watering raspberry plants during dry weather can help insure a good crop. Adequate soil moisture levels are necessary throughout the growing season for good raspberry production. However, the most critical time for moisture is from bloom until harvest. During fruit development, raspberries require 1 to 1½ inches of water (either from rain or irrigation) per week. Insufficient moisture during fruit development may result in small, seedy berries.
