How to Grow Sweet Potatoes

Sweet potatoes, with their rich flavor and versatility, are not only a nutritious addition to your diet but also a rewarding crop to grow. Whether you have a sprawling garden or limited space, sweet potatoes can be cultivated with relative ease. In this comprehensive guide, we will explore the step-by-step process of how to grow sweet potatoes, from selecting the right varieties to harvesting your own sweet, orange delights.

1. Choosing Sweet Potato Varieties

Sweet potatoes come in various varieties, each with its unique flavor profile and characteristics. Here are some popular types:

  • Beauregard: A widely grown variety known for its sweet flavor and reliable yield.
  • Jewel: Recognized for its vibrant orange flesh and excellent taste.
  • Covington: This variety is known for its disease resistance and consistent yields.
  • Japanese Sweet Potatoes: Varieties like Murasaki and Hannah are known for their purple or white flesh and nutty flavor.

Consider your taste preferences and local growing conditions when selecting sweet potato varieties.

2. Starting with Quality Sweet Potato Slips

Sweet potatoes are typically grown from “slips,” which are shoots that grow from a mature sweet potato. Here’s how to get started:

  • Purchase Slips: Obtain sweet potato slips from reputable nurseries or garden centers. Alternatively, you can grow your slips from a sweet potato.
  • Growing Slips: To grow slips at home, suspend a sweet potato in water, submerging about one-third of it. Place it in a warm, sunny location. Slips will develop within a few weeks.
  • Rooting Slips: Once slips are about 6 inches long, carefully remove them from the sweet potato and place them in water until roots develop.

3. Preparing the Soil

Sweet potatoes thrive in loose, well-draining soil. Follow these steps to prepare the soil:

  • Loosen the Soil: Use a garden fork or tiller to loosen the soil to a depth of at least 12 inches. Sweet potatoes develop underground, so loose soil allows for better tuber formation.
  • Add Organic Matter: Incorporate well-rotted compost or aged manure to improve soil fertility.
  • Soil pH: Sweet potatoes prefer slightly acidic to neutral soil with a pH level between 5.8 and 6.5. Adjust the pH if necessary using lime or sulfur.

4. Planting Sweet Potato Slips

Planting sweet potato slips is a straightforward process:

  • Spacing: Plant slips about 12 to 18 inches apart in rows spaced 3 to 4 feet apart. This provides ample space for the vines to spread.
  • Planting Depth: Place slips in the soil, leaving the leaves exposed while burying the roots. Planting depth is crucial; burying too deep can lead to rotting.
  • Timing: Plant slips after the last expected frost when the soil has warmed to at least 50°F (10°C).

5. Providing Proper Care

Sweet potatoes require care throughout their growing season. Here are essential care tips:

  • Watering: Sweet potatoes prefer consistently moist soil. Water regularly, especially during dry spells. Avoid waterlogged conditions, as this can lead to root rot.
  • Mulching: Apply a layer of organic mulch, such as straw or wood chips, to help retain soil moisture and suppress weeds.
  • Fertilization: Sweet potatoes are moderate feeders. Apply a balanced, all-purpose fertilizer at planting time and side-dress with additional fertilizer when the vines start to spread.

6. Vining and Trailing Habit

Sweet potato plants have a vining or trailing habit, meaning they spread across the ground. Here’s how to manage their growth:

  • Support or Trellis: Consider using a trellis or providing some support for the vines. This helps keep the vines off the ground, making it easier to harvest and reducing the risk of diseases.

7. Harvesting Sweet Potatoes

Harvesting sweet potatoes is a satisfying culmination of your gardening efforts. Follow these steps for a successful harvest:

  • Timing: Sweet potatoes are typically ready for harvest 90 to 170 days after planting, depending on the variety. Harvest after the vines have started to yellow and wither, signaling that the tubers have reached maturity.
  • Digging: Use a fork or shovel to carefully dig up the sweet potatoes. Take care not to damage the tubers during the harvesting process.
  • Curing: Cure sweet potatoes by allowing them to dry in a warm, well-ventilated area for about 10 to 14 days. Curing improves the flavor and helps the skins set.
  • Storage: After curing, store sweet potatoes in a cool, dark place with good ventilation. Properly stored sweet potatoes can last for several months.

8. Troubleshooting Common Issues

While sweet potatoes are relatively low-maintenance, you may encounter some common issues:

  • Pests: Keep an eye out for pests such as sweet potato weevils and aphids. Insecticidal soap or neem oil can be used for control.
  • Diseases: Practice good crop rotation to minimize the risk of diseases such as root rot. Well-draining soil and proper spacing also contribute to disease prevention.

9. Enjoying Your Sweet Potato Harvest

Once harvested and cured, sweet potatoes can be enjoyed in various ways:

  • Baking: Roast or bake sweet potatoes for a simple and nutritious side dish.
  • Mashing: Create a creamy mash with sweet potatoes, adding butter or spices for flavor.
  • Sweet Potato Fries: Slice sweet potatoes into fries, season, and bake for a healthier alternative to regular fries.
  • Pies and Casseroles: Incorporate sweet potatoes into pies, casseroles, and other baked goods for a delicious twist.


Growing sweet potatoes at home is a fulfilling experience that rewards you with a bountiful harvest of nutritious and flavorful tubers. From selecting quality slips to providing proper care throughout the growing season, each step contributes to the success of your sweet potato crop. Whether you have a backyard garden, a raised bed, or containers on a balcony, sweet potatoes can be cultivated in various settings. So, roll up your sleeves, get your hands in the soil, and enjoy the process of growing your own sweet bounty. Happy sweet potato growing!
