Sweet potatoes are a warm-season vegetable that require a long growing season that is free of frost. The vegetables are quite nutritious because they are high in fiber and vitamins A and C, according to the University of Missouri Extension. Unlike many other vegetables, sweet potatoes are planted slips that are made from seed stock. They should be planted one or two weeks after the historic last frost date for your area or when the soil temperature is at least 65 degrees F.
Prepare bed space for sweet potatoes by clearing it of all debris and weeds and other plants.
Dig a hole about 3 inches to 4 inches deep using a trowel or a small shovel.
Place a slip in the hole. The orientation of the slip does not matter because even slips planted upside down will produce sweet potatoes, according to the University of Missouri Extension.
Fill the hole in with the surrounding soil. Tamp it down firmly with your hands to remove any pockets of air from the soil.
Water the sweet potatoes immediately after planting. Sweet potatoes need 1 inch of water per week, so they will need to be watered during extended dry spells, according to the University of Missouri Extension.
