Sow and Plant

Plant 'slips' that grow from sprouting tubers in late spring or early summer, after the soil is very warm.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.


Sweet potatoes form a dense green ground cover, thriving in hot summer conditions. Tubers are often found 12 inches or more from the plant's primary crown, so dig carefully.


Dig in autumn when the soil is still warm. Cure in a warm, airy place for two weeks before storing at cool room temperatures.
