The water requirement of cranberries during the growing season can vary from 0.4 to over 1.5 inches per week. Because of this variability, it is essential to adjust water management practices based on soil moisture monitoring to avoid deficit or excess conditions. In periods of low rainfall and high demand, cranberries must be supplied with additional water through irrigation. During periods of high rainfall, adequate drainage must be supplied to avoid damaging anaerobic conditions in the root zone. In general, cranberries are irrigated by manipulation of the water table or through the use of low-gallonage sprinkler systems or some combination of the two.
