Choose Healthy Slips:
Pick sturdy, disease-resistant sweet potato slips from a nursery.
Prepare the Trellis:
Erect a sturdy trellis structure that can support vine growth.
Planting:
Space the slips 12-18 inches apart at the base of the trellis, covering the roots gently.
Soil Prep:
Enhance soil with compost or potting mix and, optionally, organic fertilizer for nutrients.
Train the Vines:
Guide vines upwards using soft ties to prevent damage.
Mulch and Water:
Mulch around plants to retain moisture and water regularly, keeping soil consistently moist but not waterlogged.
Prune and Maintain:
Trim excess growth to prevent overcrowding and remove any yellowing leaves promptly.
Harvesting:
Dig around the base of vines to unearth tubers 3-4 months after planting. Let harvested sweet potatoes cure in a warm, dry spot for 1-2 weeks.
Storage:
Store in a cool, dark, ventilated area; avoid refrigeration.
With these steps, you’ll soon enjoy a hearty harvest of sweet potatoes from your trellis garden.
