How to Grow Sweet Potatoes in Georgia

Sweet potatoes are a versatile and nutritious vegetable that can be grown successfully in Georgia’s climate. With the right techniques and care, you can enjoy a bountiful harvest of this delicious root crop. In this article, we will guide you through the process of growing sweet potatoes in Georgia and answer some frequently asked questions about their cultivation.

1. Choose the Right Variety: Select sweet potato varieties that thrive in Georgia’s climate. Popular varieties include Beauregard, Georgia Jet, and Vardaman.

2. Soil Preparation: Sweet potatoes prefer well-drained soil with a pH level between 5.8 and 6.2. Amend the soil with organic matter like compost or aged manure before planting to improve its fertility and drainage.

3. Planting: Sweet potatoes are typically grown from slips, which are young rooted shoots. Plant slips in early spring, once the soil temperature reaches 50°F (10°C). Space the slips 12-18 inches apart in rows that are 3-4 feet apart.

4. Sun Exposure: Sweet potatoes require full sun exposure to grow and produce a good harvest. Choose a location in your garden that receives at least six hours of direct sunlight daily.

5. Watering: Provide consistent moisture to the sweet potato plants throughout their growing season. Water deeply once a week, ensuring the soil remains evenly moist but not waterlogged.

6. Fertilization: Sweet potatoes are heavy feeders and benefit from regular fertilization. Apply a balanced fertilizer, such as 10-10-10, at planting time and side-dress with nitrogen-rich fertilizer six weeks after planting.

7. Weed Control: Keep the sweet potato beds weed-free to prevent competition for nutrients and water. Mulching can help suppress weeds while retaining soil moisture.

8. Disease and Pest Management: Sweet potatoes are susceptible to certain diseases and pests, such as sweet potato weevils and root rot. Monitor your plants regularly and take appropriate measures, such as using organic insecticides or disease-resistant varieties, to control these issues.

9. Harvesting: Sweet potatoes are ready to harvest when their leaves start to yellow and die back, usually around 100-120 days after planting. Carefully dig up the tubers, being careful not to damage them. Cure them in a warm and well-ventilated area for about 10 days to improve their flavor and storage life.

10. Storing: After curing, store sweet potatoes in a cool (55-60°F/12-15°C), dry, and dark place. They can last for several months under proper storage conditions.

11. Crop Rotation: Practice crop rotation to prevent the buildup of soil-borne diseases and pests. Avoid planting sweet potatoes in the same spot for at least three years.

12. Companion Planting: Consider planting sweet potatoes alongside companion plants like beans, corn, or leafy greens. These plants can help deter pests and provide shade and support for the sweet potato vines.
