Potatoes should be planted in sandy, well-drained soil in trenches that are 4 inches deep. The bottom of the trenches should be spread with rotted manure or compost before planting.
The potatoes can be planted directly after the last spring frost or as soon as the ground can be worked. They can be bought as seed potatoes, or a whole potato can be cut up. The sections or the seed potato should have at least two eyes. If a whole potato is cut up, the sections should be allowed to rest for one or two days so they can form a layer to guard against rot and to hold in moisture.
Seed potatoes should be planted 1 foot apart with their eyes up. Potatoes do best in moist soil, so the plot needs to be well-watered, especially when the tubers start to form.
The plant should be hilled when it is about 6 inches tall and before it blooms. The gardener should mound the soil around the base of the plant with a hoe. This makes sure that the roots have good cover, the plant is supported and the potatoes do not get sunburned. Sunburned potatoes are green and have a bitter taste. The plants need to be hilled approximately every two weeks.
