Rainfall amounts this spring have been below normal in most areas of Iowa. If the dry conditions persist, the yields of strawberries and raspberries could be reduced.
Strawberries and raspberries require adequate moisture throughout the growing season for good fruit production. However, the most critical time is from bloom to the end of the harvest. Insufficient moisture during fruit development may cause the fruit to fail to develop full size or to dry up. If rainfall is inadequate, apply 1 to 1 1/2 inches of water per week.
