- Planting Slips: Utilize sweet potato slips for planting, ensuring they are spaced 12-18 inches apart after the last frost in late spring.
- Watering Needs: Regularly water sweet potato plants to maintain 1 inch of moisture weekly, especially during dry spells, while avoiding overwatering.
- Weed & Pest Control: Use mulch to suppress weeds and monitor for pests like vine borers and aphids, applying organic insecticides if necessary.
- Harvesting Techniques: Harvest sweet potatoes 90-120 days after planting by checking for yellowing leaves and tuber size, and handle them gently to avoid damage.
- Curing & Storage: Cure harvested sweet potatoes in a warm and humid environment for 10 days to enhance flavor before storing them in a cool, dark place.
How To Grow Sweet Potatoes In Garden
Choose the Right Location
Select a sunny spot for your sweet potatoes. A location with at least 6 hours of full sunlight daily promotes healthy growth. Ensure the area has well-draining soil to prevent root rot.
Prepare the Soil
Loosen the soil to a depth of 12 inches. Sweet potatoes thrive in sandy or loamy soil rich in organic matter. Incorporate compost or aged manure to enhance fertility.
Obtain Sweet Potato Slips
Purchase sweet potato slips, which are young plants. You can also create slips by placing whole sweet potatoes in water until they sprout. Each slip should have at least one vigorous shoot.
Plant the Slips
Plant slips after the danger of frost has passed, usually in late spring. Space slips 12 to 18 inches apart in rows that are 3 feet apart. Bury the slips up to the first set of leaves, ensuring good soil contact.
Water Adequately
Water your sweet potatoes regularly, especially in dry spells. They require 1 inch of water weekly. Avoid overwatering, as excess moisture can lead to rot.
Control Weeds and Pests
Maintain a weed-free environment by mulching around plants. Use straw or wood chips to suppress weeds. Monitor for pests like vine borers and aphids. Remove them manually or apply organic insecticides if necessary.
Harvesting Sweet Potatoes
Harvest occurs 90 to 120 days after planting. Look for signs of yellowing leaves and wilting vines. Gently dig around the base of the plant to avoid damaging the tubers.
Storage Tips
After harvesting, cure sweet potatoes in a warm, humid location for 10 days. This enhances their flavor and shelf life. Store cured sweet potatoes in a cool, dark place.
Final Notes
Growing sweet potatoes is rewarding and straightforward. With the right conditions and care, you’ll enjoy a bountiful harvest of this nutritious vegetable.
Preparing The Soil
Preparing the soil for sweet potatoes lays the foundation for a successful harvest. Focus on a few key aspects to ensure optimal growing conditions.
Choosing The Right Location
Choose a sunny spot for growing sweet potatoes. Full sun exposure, around six to eight hours daily, ensures robust growth. Look for locations with well-draining soil. Raised beds or mounds are excellent choices if your native soil retains too much moisture. You can also check for proximity to your water source, as sweet potatoes require consistency in watering.
Soil Amendments
Enrich your soil before planting sweet potatoes. Incorporate organic matter like compost or well-rotted manure to improve soil structure and nutrient levels. Aim for a balance of nutrients, focusing on phosphorus and potassium, as they support tuber development. Test your soil pH; sweet potatoes thrive in slightly acidic to neutral ranges, around 5.8 to 6.5. If needed, add lime to raise the pH, or sulfur to lower it, adjusting according to your soil test results.
By ensuring your soil is well-prepared, you maximize the chances of a healthy sweet potato crop.
Planting Sweet Potatoes
Planting sweet potatoes involves careful consideration of the right materials and techniques. This step is crucial for ensuring a bountiful harvest.
Seed Potatoes Vs. Slips
Sweet potatoes propagate from slips, which are sprouts grown from a whole sweet potato. You can purchase slips from nurseries or online stores, ensuring they are disease-free. If you prefer to grow your slips, place whole sweet potatoes in water, allowing them to sprout. Cut the sprouted sections, known as slips, after they reach about 6 inches in length. In contrast, traditional seed potatoes are used for standard potatoes. Remember, sweet potatoes require specialized slips for optimal growth.
Planting Techniques
Plant slips in late spring, after the threat of frost has passed. Ensure the soil temperature is consistently above 60°F. Space slips 12 to 18 inches apart in rows 3 feet apart. Plant slips deep enough to cover the roots and half to two-thirds of the stem. Firm the soil around each slip to eliminate air pockets. Water immediately after planting to settle the soil and reduce transplant shock. Maintain consistent moisture, particularly during dry spells. If preferred, create raised beds for improved drainage and warmth, which enhances tuber development.
By adopting these planting techniques, you encourage healthy growth and maximize your sweet potato yield.
Caring For Sweet Potato Plants
Caring for sweet potato plants ensures strong growth and a healthy harvest. Focus on watering, pest management, and disease prevention to achieve the best results.
Watering Requirements
Watering sweet potato plants consistently is crucial. Aim for about 1 inch of water per week, including rainfall. During dry spells, water deeply to reach the roots. Check soil moisture by sticking your finger about an inch into the soil. If it’s dry, it’s time to water. Mulching around the plants helps retain soil moisture and suppress weeds. Adjust your watering schedule if the leaves begin to wilt or yellow, indicating stress.
Pest And Disease Management
Managing pests and diseases protects your sweet potato plants. Common pests include sweet potato weevils and aphids. Inspect plants regularly for signs of infestation. Handpick pests when possible or use insecticidal soap for larger outbreaks.
Practice crop rotation to reduce pest buildup and disease spread. Fungal and bacterial diseases like root rot can also affect sweet potatoes. Ensure proper air circulation by spacing plants adequately and removing any debris. If disease strikes, removing affected plants promptly helps contain the problem. Choosing disease-resistant varieties simplifies management and enhances your harvest.
Harvesting Sweet Potatoes
Harvesting sweet potatoes requires careful observation and timing. Expect to harvest around 90 to 120 days after planting. Select a dry day to facilitate handling and storage.
Signs Of Readiness
Watch for these signs to determine when your sweet potatoes are ready for harvest:
- Foliage Color: Leaves may yellow and begin to die back, indicating that tuber development is complete.
- Tuber Size: Gently dig around a few plants to check tuber size. Aim for tubers that are a minimum of 2 to 3 inches in diameter.
- Flowering: Blooms on some varieties signal maturity, although not all sweet potatoes flower.
Harvesting Techniques
Use these techniques when harvesting sweet potatoes to prevent damage:
- Loosen the Soil: Use a garden fork or spade, inserting it carefully about 6 inches away from the base of the plant. This minimizes the risk of puncturing the tubers.
- Lift the Tuber: Gently lift the plant to expose the tubers. Handle each tuber with care to avoid bruising.
- Inspect Each Tuber: Check for irregularities like soft spots or damage. Set aside any that show signs of rot.
- Cure the Tubers: After harvesting, place the tubers in a warm, humid spot for 1 to 2 weeks to enhance sweetness and promote better storage.
By paying attention to signs of readiness and using proper harvesting techniques, you’ll ensure a successful yield of sweet potatoes.
Conclusion
Growing sweet potatoes can be a fun and rewarding experience. With a bit of care and attention you can enjoy a bountiful harvest of these delicious tubers. Remember to provide them with plenty of sunlight and moisture while keeping an eye out for pests.
Don’t forget the curing process after harvesting to bring out their natural sweetness. Whether you’re a seasoned gardener or just starting out sweet potatoes can be a delightful addition to your garden. So grab your slips and get started on this tasty journey. Happy gardening!

My interest in trees started when I first saw the giant sequoias in Yosemite.
I was a teenager then, and I remember thinking, “I need to learn more about this.”
That moment stuck with me.
A few years later, I went on to study forestry at Michigan Tech.
Since graduating, I’ve worked in a mix of hands-on tree care and community education.
I’ve spent over ten years helping people understand how to plant, maintain, and protect the trees in their neighborhoods.
I don’t see trees as just part of the landscape.
They are living things that make a real difference in our daily lives.
