This comprehensive guide will provide you with all the essential knowledge and techniques to successfully cultivate and harvest this nutritious leafy green.
1. Selecting the Right Sweet Potato Variety
The first step in growing sweet potato leaves is selecting the right variety. Not all sweet potato varieties are suitable for leaf production. Some popular choices for growing leaves include:
- Beauregard: Known for its large, tender leaves and high yield.
- Jewel: Produces dark green, flavorful leaves and is resistant to pests and diseases.
- Vardaman: A compact variety with sweet, tender leaves and a good yield.
- Georgia Red: Produces purplish-red leaves with a slightly bitter taste.
2. Planting Sweet Potato Slips
Sweet potato leaves are grown from slips, which are young shoots that develop from the roots of mature sweet potatoes. To obtain slips, you can either purchase them from a nursery or grow your own by following these steps:
1. Select healthy, disease-free sweet potatoes.
2. Place the sweet potatoes in a warm, humid environment, such as a propagator or a warm windowsill.
3. Keep the sweet potatoes moist and wait for slips to emerge.
4. Once the slips are 4-6 inches long, carefully remove them from the sweet potatoes.
3. Preparing the Planting Site
Sweet potato leaves thrive in well-drained, sandy loam soil with a pH between 5.5 and 6.5. Choose a planting site that receives full sun for at least 6 hours per day. If your soil is heavy or compacted, consider amending it with compost or other organic matter to improve drainage and fertility.
4. Planting the Sweet Potato Slips
When the soil temperature reaches at least 65°F (18°C), you can plant the sweet potato slips. Space the slips 12-18 inches apart in rows that are 3-4 feet apart. Plant the slips shallowly, with only the roots covered. Water the slips thoroughly after planting.
5. Caring for Sweet Potato Leaves
Sweet potato leaves require regular care to thrive. Here are some essential care tips:
- Watering: Water the sweet potato leaves regularly, especially during dry spells. Aim to keep the soil consistently moist but not waterlogged.
- Fertilizing: Apply a balanced fertilizer, such as a 10-10-10 fertilizer, every 4-6 weeks to promote healthy growth.
- Weeding: Keep the planting site free of weeds, as they can compete with the sweet potato leaves for nutrients and water.
- Pest and Disease Control: Monitor the sweet potato leaves for pests and diseases. Common pests include aphids, whiteflies, and spider mites. Common diseases include sweet potato mosaic virus and Fusarium wilt.
6. Harvesting Sweet Potato Leaves
Sweet potato leaves can be harvested when they are tender and young, typically around 6-8 weeks after planting. To harvest the leaves, simply pinch or cut them off the stem. Avoid harvesting the leaves from the center of the plant, as this can stunt growth. You can harvest the leaves multiple times throughout the growing season.

Sweet potato leaves are a versatile ingredient that can be used in various culinary preparations. Here are some popular ways to enjoy sweet potato leaves:
- Stir-fries: Add sweet potato leaves to stir-fries for a nutritious and flavorful addition.
- Soups and stews: Use sweet potato leaves in soups and stews for a boost of vitamins and minerals.
- Salads: Sweet potato leaves can be added to salads for a fresh and crunchy texture.
