Introduction

Sweet potatoes are a delicious and nutritious crop that is easy to grow, provided you start with the right foundation: sweet potato slips. Unlike regular potatoes, which are grown from seed potatoes, sweet potatoes are propagated using sprouts known as slips. These slips are shoots that develop from a mature sweet potato and can be transplanted into your garden for a bountiful harvest.

Making your own sweet potato slips is an economical and rewarding process that ensures you have healthy plants free from harmful chemicals or diseases. This guide will take you through the step-by-step process of growing and preparing sweet potato slips to guarantee a thriving garden.

Why Grow Your Own Sweet Potato Slips?

Many gardeners prefer growing their own sweet potato slips instead of purchasing them because:

  • Cost-effective: Store-bought slips can be expensive, while homegrown slips are practically free.
  • Control Over Quality: You can select the healthiest sweet potatoes to ensure strong and disease-free plants.
  • More Variety: Store-bought slips may have limited options, but growing your own allows you to choose heirloom or unique varieties.
  • Satisfaction: There’s a unique joy in growing a plant from scratch and watching it thrive.

Step-by-Step Guide to Making Sweet Potato Slips

Step 1: Selecting the Right Sweet Potato

Start by choosing a healthy, organic sweet potato. Non-organic sweet potatoes may be treated with growth inhibitors to prevent sprouting, making them unsuitable for slip production.

Tips for selecting a good sweet potato:

  • Choose firm, unblemished tubers without signs of rot or mold.
  • Opt for organic varieties to ensure no chemicals prevent sprouting.
  • Select different varieties if you want a mix of flavors and textures.

Step 2: Preparing the Sweet Potato for Sprouting

There are two popular methods for sprouting sweet potatoes: the water method and the soil method.

Water Method

  1. Cut the sweet potato in half or leave it whole.
  2. Insert three to four toothpicks into the sides of the sweet potato to suspend it in a jar of water.
  3. Place the sweet potato in the jar with one-half submerged in water.
  4. Keep the jar in a warm, sunny location (70–80°F).
  5. Change the water every few days to prevent mold and bacteria.
  6. In 2-4 weeks, sprouts (slips) will start emerging from the top.

Soil Method

  1. Place the sweet potato in a container filled with moist potting soil or sand.
  2. Cover the lower half of the tuber with soil.
  3. Keep the container in a warm spot (70–80°F) with indirect sunlight.
  4. Keep the soil moist but not waterlogged.
  5. In 2-4 weeks, sprouts will begin growing.

Step 3: Harvesting the Slips

Once the sweet potato has sprouted and the slips have grown to about 6-12 inches long, they are ready for harvesting.

How to remove slips:

  • Gently twist or cut the slip from the sweet potato at its base.
  • If the slip already has roots, you can plant it directly into soil.
  • If it lacks roots, place it in a jar of clean water and let it root.

Step 4: Rooting the Slips (If Necessary)

If your slips do not already have roots, you can encourage root growth before planting.

  1. Place slips in a glass of water, submerging only the bottom half.
  2. Set the glass in a warm, sunny window.
  3. Change the water every few days to keep it fresh.
  4. In about 1-2 weeks, small white roots will begin to form.

Once roots are 2 inches long, your slips are ready for transplanting into the garden.

Step 5: Planting the Slips in the Garden

Sweet potatoes thrive in warm, loose, well-drained soil. Follow these steps for planting:

  1. Choose the right location:
    • Pick a sunny spot with at least 6-8 hours of direct sunlight daily.
    • Avoid areas prone to waterlogging, as sweet potatoes need well-draining soil.
  2. Prepare the soil:
    • Loosen the soil to a depth of 8-12 inches.
    • Add organic compost or aged manure for better fertility.
    • If soil is heavy, consider raised beds or mounds to improve drainage.
  3. Plant the slips:
    • Space each slip 12-18 inches apart in rows 3-4 feet apart.
    • Bury slips deep enough so that only the top leaves are above the soil.
    • Water thoroughly after planting.

Step 6: Caring for Sweet Potato Plants

Once planted, your sweet potato slips need proper care to thrive:

✅ Watering: Keep soil moist but not soggy. Water regularly, especially during dry periods. ✅ Mulching: Apply a layer of mulch to retain moisture and prevent weeds. ✅ Weeding: Keep the area around the plants free of weeds. ✅ Fertilizing: Avoid high-nitrogen fertilizers, which encourage excessive vine growth at the expense of tuber development. ✅ Pest Control: Watch out for sweet potato weevils and nematodes; use organic pest control if necessary.

Step 7: Harvesting Your Sweet Potatoes

After 90-120 days, your sweet potatoes will be ready for harvest.

  1. Look for yellowing leaves, which indicate maturity.
  2. Use a garden fork to gently lift the tubers from the soil.
  3. Let them cure in a warm, humid area for 7-10 days before storage.

Proper curing enhances the sweetness and shelf life of your harvest.

Conclusion

Growing sweet potato slips at home is an easy, sustainable, and cost-effective way to start a successful sweet potato crop. Whether you use the water method or soil method, following these steps will ensure a healthy and abundant harvest.
