Sweet Potato
Sweet potato is a tender vine crop grown from slips for sweet starchy tubers in the warmest parts of the season. It is more demanding than ordinary potato, but can succeed well in protected growing and warm free-draining soils.

Care tips
Start only once temperatures are dependable, because cool conditions can check plants badly and reduce yields. Use free-draining soil or raised beds, avoid overwatering in cool weather, and cure harvested tubers warm and dry so skins toughen and flavour improves.
Common pests
Slugs, wireworm, vine weevil, rot in cold wet soils.
