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. Although not from the solanaceae family, sweet potatoes are often placed in that group for crop rotation purposes because they share several important pests and diseases such as wireworms and nematodes which is why we show it as solanaceae.

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.
