The harvest requires frequent, light irrigation, spaced out to ensure deep-down moisture with no breaks. Irrigation every 2 to 4 days is common practice.
Over-irrigation often causes the spread of disease such as mildew and white rot. Irrigation may be interrupted 15 to 25 days before harvest if necessary.
Spray irrigation provides for significant water savings compared to traditional techniques. Micro irrigation or solid sets is mostly recommended, depending on the recommended farm size.
