Sweet Potatoes Planting & Care Guide

Sweet Potatoes Care Guide

  • Use Vital Earth Organic Compost or Acidified Compost for amending native soil.
  • Sweet potatoes need excellent drainage. Consider adding Expanded Shale to make sure it drains well.
  • Planting in raised beds is another option to ensure the best drainage.
  • See the Vegetable Gardening Project List handout for soil recipe recommendations.
  • Feed with a good organic fertilizer monthly, such as Espoma Garden-Tone.

Sweet Potato Planting in North Texas

  • Select a site that receives 6 or more hours of direct sunlight, and plant only when temperatures are consistently warm.
  • Make sure your sweet potatoes have plenty of room to grow — vines sprawl and can get quite large!
  • Use our recommended soil mix or Mayer Materials’ Raised Bed Mix for raised beds, or NHG Organic Premium Potting Soil for containers. Sweet potatoes need consistent moisture and well drained soil.
  • Set slips (plants) as soon as possible after purchase. Place roots in the ground and plant about halfway up the stem, 3-4″ deep. Set slips 2 feet apart in the garden or use a 20-24″ container. Water slips in well at planting.
  • Feed monthly with a quality organic plant fertilizer such as Espoma Garden-Tone according to package directions.
  • Sweet potatoes mature 90-120 days after planting. Check size of tubers by carefully removing soil from around root area. If tubers are about 6″ long, it’s time to harvest!
  • Harvest your sweet potatoes. Cautiously dig tubers with a large fork or shovel, or even better, by hand. Handle carefully, as the skin of freshly dug sweet pota-toes is very delicate. Try to avoid nicks and scrapes.
  • Dry freshly dug sweet potatoes outdoors in the shade for several hours, then place tubers in a basket or crate and do not wash dirt off. Keep at room tem-perature and dry, preferably in a space with high humidity like a laundry room.
