Sweet potato growing on a trelis

Short comments

Scrambling vine. Edible leaves like spinnach.

General comments

Ecology

Best planted in separate beds. Require long warm growing season. Plant in free draining soil. Fertilise before planting, too much fertiliser will encourage vine growth rather than tuber growth.

Dry harvested tubers in sun for a couple of days following harvesting, then store in a cool dry place.

Companion plant with Cowpea.

Uses

Ground cover, edible.

Food

Use mashed, boiled, roasted, baked or fried. Or use in soups, pies, casseroles, curries and salads. Leaves are edible and are cooked like spinach.

Planting Depth

Harder soil with a mulch layer will promote fatter tubers, whereas friable soil can promote longer and skinnier tubers.

Growth from supermarket

Sweet potato's can be grown from tubers purchased from the supermarket. Beware that this can introduce disease into your garden.

  • Wash the potato
  • Leave in cupboard to sprout
  • Plant

Alternatively, you can cut the tuber into 25mm chunks, allow the sides to dry and then place in a saucer of water to promote growth, watch for mold and change the water as necessary.
