Whether you’re a seasoned gardener or a newbie, learning how to grow the best sweet potato can be a rewarding experience. This guide will walk you through the process, from choosing the right variety to harvesting plump, flavorful tubers.

Choosing the Right Sweet Potato Variety

The first step to growing the best sweet potato is selecting the right variety. Consider your climate, soil type, and desired flavor profile. Here are some popular options:

• Beauregard: This classic variety boasts a deep orange flesh and a sweet, rich flavor. It’s well-suited for both fresh eating and storage.
• Covington: Known for its smooth, reddish-purple skin and creamy orange flesh, Covington is a good choice for baking and roasting.
• Jewel: This variety offers a vibrant orange flesh and a sweet, moist texture, making it ideal for candied sweet potatoes.
• Purple Yam: This unique variety features a deep purple flesh and a mild, slightly nutty flavor. It’s a beautiful addition to salads and desserts.

Preparing the Soil

Sweet potatoes thrive in well-drained, sandy loam soil with a pH of 6.0 to 6.8. Here’s how to prepare your garden bed:

• Amend the Soil: If your soil is heavy clay, incorporate organic matter like compost or well-rotted manure to improve drainage and aeration.
• Test the pH: Use a soil testing kit to determine your soil’s pH. If it’s too acidic, add lime to raise the pH.
• Remove Weeds: Clear the garden bed of any weeds that could compete with your sweet potato plants.

Planting Sweet Potatoes

Sweet potatoes are typically started from slips, which are small shoots that grow from the potato’s roots. Here’s how to plant them:

• Start Slips: Purchase slips from a reputable nursery or start your own. To start your own, place a sweet potato in a shallow dish filled with water and wait for slips to sprout.
• Space Slips: Plant slips 12-18 inches apart in rows 3-4 feet wide.
• Planting Depth: Plant slips 2-3 inches deep, ensuring the top portion of the slip is above ground.
• Water Thoroughly: After planting, water the slips well to help them establish roots.

Providing the Right Care

Once your sweet potato plants are in the ground, they need consistent care to thrive. Here are some essential tips:

• Watering: Keep the soil consistently moist but not waterlogged. Water deeply and infrequently, allowing the top inch of soil to dry out between waterings.
• Fertilizing: Sweet potatoes are moderate feeders. Fertilize every 4-6 weeks with a balanced fertilizer, such as 10-10-10.
• Weeding: Regularly weed around your plants to prevent competition for nutrients and water.
• Hilling: As your plants grow, mound soil around the base of the stems to encourage more root growth. This process, called hilling, helps to prevent the roots from being exposed to the sun.

Protecting Your Sweet Potatoes from Pests and Diseases

Sweet potatoes are susceptible to a few common pests and diseases. Here are some tips for prevention and control:

• Sweet Potato Weevil: This destructive pest can damage the roots and stems. To prevent weevils, use row covers or plant resistant varieties.
• Fungal Diseases: Sweet potatoes can be affected by fungal diseases like root rot and leaf spot. Proper drainage and spacing can help to prevent these diseases.

Harvesting Your Sweet Potatoes

Sweet potatoes are typically ready for harvest 100-120 days after planting. Here’s how to harvest them:

• Timing: Harvest your sweet potatoes when the leaves start to turn yellow and die back.
• Digging: Use a garden fork or shovel to gently dig around the base of the plant. Be careful not to damage the roots.
• Cleaning: Brush off any excess dirt and store your sweet potatoes in a cool, dry place.

Storing Your Sweet Potato Bounty

Proper storage is essential for preserving the quality and flavor of your sweet potatoes. Follow these steps:

• Curing: After harvest, cure your sweet potatoes for 10-14 days in a warm, dry place with good air circulation. This process helps to dry the skin and improve their storage life.
• Storage Conditions: Store cured sweet potatoes in a cool, dry place with temperatures between 55 and 60 degrees Fahrenheit. Avoid storing them near other fruits and vegetables that produce ethylene gas, which can accelerate spoilage.
