Sweet Potato

1) Plant History & General Information:








2) Plant Uses:

  • As Food: Used mostly for human consumption; large edible root and edible leaves
  • As Medicine:  Sweet potatoes are extraordinarily rich in carotenoids, orange and yellow pigments that play a role in helping the body respond to insulin. And as unlikely as it may seem, coffee (another Magic food) and sweet potatoes have something in common: They’re both rich in the natural plant compound chlorogenic acid, which may help reduce insulin resistance.
  • The famous Nurses’ Health Study at Harvard Medical School found that women who ate lots of foods rich in beta-carotene, such as sweet potatoes, reduced their risk of breast cancer by as much as 25 percent. Eating sweet potatoes is a smart move for you if you have high blood pressure because they are rich in potassium, a mineral known for bringing pressure down. You’ll get more potassium from a sweet potato than you will from a banana!
  • Other Uses: Sweet potato vines also provide the basis for a high-protein animal feed. With high starch content, it is well suited to processing and has become an important source of raw material for starch and starch-derived industrial products.

3) Growing Instructions

  • Growing: Grows like a weed. The plant does not enjoy frost. It grows best at an average temperature of 24 °C (75 °F), abundant sunshine and warm nights.
  • Best time to Harvest: Depending on the climate and conditions, tuberous roots mature in two to nine months.
  • Sunlight Requirements: Full Shade, Partial Shade, Full Sunlight
  • Soil Requirements: Although sweet potatoes may be grown on various types of soil, best results and highest yields will be obtained on soils that are loose, free from rocks, fairly fertile with a pH of 5.0 to 6.0 and with good drainage. Sweet potatoes are grown in tightly packed or rock-filled soils will produce many misshapen roots.
