Potatoes prefer cool weather and can be planted very early in the gardening season—as you soon as the frost is out of the soil and you are able to work the soil. In Northern regions, some gardeners will plant the first crop of early-maturing potatoes in early to mid-April, 6 to 8 weeks before the average last frost date or as soon as the soil can be worked. They can survive some cool weather but the threat of frost is a gamble. If there is a threat of frost at night, temporarily cover any sprouted foliage with mulch or an artificial covering such as old sheets or plastic containers - and be sure to remember to remove the coverings in the morning. Choose a location that gets full sun—at least 6 hours each day - and grow potatoes in trenched rows spaced about 3 feet apart.
