Irrigation

Cucumber requires a constant water supply to reach hiqh quality and yields. Periods of growth when the plant is most susceptible to irrigation deficits include seed germination, flowering, and fruit enlargement. The frequency of irrigation is largely dependent on soil type and weather conditions. In general, for sandy soils with dry weather, the fields should be irrigated at least every other day if not more often at a rate of 1-2 inches per week. Cucumber in Hawaii is normally drip irrigated. Two or three weeks after planting, a second drip line is installed about 18 inches parallel from the one applied at planting. Thus, there is a drip line on both sides of the row. In sprinkle-irrigated fields, avoid irrigation between 8-11 AM to prevent interference with honeybees.
