Mound the soil into a raised rows to a height of 8 to 12 inches and 6 to 8 inches wide, spaced 3 to 4 feet apart. This provides loose soil for the formation of tubers and promotes healthy growth. Plant sweet potato slips 10 to 12 inches apart and firm the soil down with your hands to secure the plant. Water thoroughly to moisten the mound of soil.

In order to grow and harvest sweet potatoes, the soil needs to be kept moist during the season where the plants sprout. Furthermore, growing sweet potatoes requires the soil temperature to be kept at 70 to 80 F. (21-26 C.). Because of the warmth required in the soil, you should start sweet potatoes about mid-summer. Otherwise, the soil wonât be warm enough for these plants to grow. When you grow and harvest sweet potatoes, from the moment you plant the slips, it takes only six weeks for the sweet potatoes to be ready. Plant the slips 12 to 18 inches apart on a wide, raised ridge that is about 8 inches tall.
