Plant potatoes in an area of the garden where they will receive full sun, in the early spring. Never plant any kind of potato when the temperature will dip below 45 degrees Fahrenheit and grow them in rows, at least 3 feet apart.
Before planting potatoes, place the seed potatoes in a place where they will receive bright sunlight, but in an area that doesn't get above 70 F. This will begin the sprouting process. Larger potatoes should be cut into smaller pieces a day or two before planting, ensuring each piece contains at least one eye bud.
Plant potatoes in trenches that are 3-feet apart, at least 6-inches deep, and with about 4-inches of soil covering the tops. Keep the soil moist as the potatoes begin sprouting vines. This is especially important during the summer months. Eventually the potatoes will flower, and when these flowers begin dying, the potatoes will not need as much water.
Properly cared for, baby potatoes will be ready for harvest 2 to 3 weeks after these flowers die. Only the largest potatoes should be harvested. By leaving the small potatoes in the ground, they will continue growing. when digging up the potatoes, dig around the plants and try not to damage those left in the ground.
