How to Grow Sweet Potatoes

Sweet potatoes are a warm-season crop that thrives in sunny conditions. They are nutrient-rich and versatile in cooking. Here�s a detailed guide to growing your own sweet potatoes using organic practices.

What You’ll Need

  • Sweet potato slips
  • Loamy, well-draining soil
  • Compost
  • Mulch
  • Watering can or hose

Selecting Varieties

There are several varieties of sweet potatoes to choose from, each with unique characteristics:

  • Beauregard: Orange flesh, excellent yield.
  • Covington: Sweet and moist, deep orange flesh.
  • Japanese: Purple skin with white flesh, dry texture.

Soil Preparation

Sweet potatoes prefer sandy, well-drained soil with a pH of 5.5-6.5. Prepare your soil as follows:

  1. Loosen the Soil: Till the soil to a depth of 12-15 inches (30-38 cm).
  2. Enhance Fertility: Incorporate 2-3 inches (5-7.5 cm) of compost to enrich the soil.

Planting Sweet Potato Slips

Plant slips after the last frost has passed:

  1. Spacing: Plant slips 12-18 inches (30-45 cm) apart in rows 3 feet (90 cm) apart.
  2. Depth: Insert slips deep enough to cover the roots and part of the stem.

Watering and Mulching

Maintain consistent moisture for optimal growth:

  • Watering: Water regularly, keeping the soil moist but not soggy.
  • Mulching: Use straw or leaf mulch to retain moisture and suppress weeds.

Organic Fertilizing

Boost growth with organic fertilizers:

  • Apply compost tea or seaweed extract every 3-4 weeks during the growing season.

Harvesting Sweet Potatoes

Sweet potatoes are ready to harvest when the leaves start to yellow:

  • Timing: Typically 90-120 days after planting.
  • Method: Use a garden fork to gently dig up the tubers.

Storing Your Harvest

Proper storage extends shelf life:

  • Curing: Cure sweet potatoes in a warm, humid place for 1-2 weeks.
  • Storage: Store in a cool, dry place for up to 6 months.

Additional Tips

  • Rotate crops annually to prevent soil depletion and pest buildup.
  • Consider companion planting with beans and marigolds for better growth and pest control.
