It is a good idea to rotate spots in the Garden for potato production. Planting in the same area year after year may lead to disease and insect problems. Irrigation Keep soil moist but not wet. Potatoes require abundant oxygen and do not flourish in compacted soils. Generally, potatoes have a shallow root system.
Most moisture is taken up from the top foot of soil.
Be particularly careful to avoid overwatering during the first weeks after planting. After plants have emerged, irrigate every three to five days, thoroughly wetting the soil to a depth of about 2 feet. Do not subject potato plants to water stress, as this will result in lower yield and misshapen tubers. Water stress is indicated by wilting and a dark gray-green hue to the foliage. Leaflets may roll slightly.
