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

Notes
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.
|
Harvesting
Dig in autumn when the soil is still warm. Cure in a warm, airy place for two weeks before storing at cool room temperatures.
|
Troubleshooting
Deer are fond of sweet potato vines.
