About Sweet Potato

Sweet potatoes need a long warm season and thrive in heat — they are a subtropical crop at heart.

Plant slips (rooted cuttings) after soil warms to 18°C. They sprawl — give them space or train vertically. Cure harvested tubers at 30°C for a week to develop sweetness and improve storage.
