How to grow

Cultivation

Grow in deep fertile soil in a frost free spot with full light. Can be grown outdoors once all danger of frost is past, but needs a long growing period to produce a root crop. Can be grown in a large container. Train up a cane to save space, along the ground as ground cover, or allow to trail downards from a container. Eating the leaves as a vegetable will limit its size, but at the expense of the root harvest. For more advice see sweet potato cultivation

Propagation

Propagate by dividing a tuber into 'slips', which are slices of tuber that include a bud. For more advice see sweet potato cultivation
