Step 7: Manage Growth
Sweet potato vines spread quickly. You can:
-
Let them sprawl across the ground.
-
Use a trellis to save space and keep vines tidy.
Prune extra leaves occasionally to help the plant focus energy on growing tubers.
Step 8: Watch for Pests and Disease
Common issues include aphids and fungal infections. Keep the area clean and dry, and inspect plants regularly.
Tip: Neem oil spray can help control pests naturally.
Step 9: Harvest Time
After 3–4 months, you’ll notice the vines turn yellow and start to die back—that means it’s harvest time.
-
Use your hands or a garden fork to gently dig around the plant.
-
Be careful not to bruise the tubers.
-
Cure harvested sweet potatoes in a warm, humid place (around 85°F) for 1–2 weeks to bring out their sweetness.
Step 10: Store Properly
Store cured sweet potatoes in a cool, dark place (55–60°F). A basement or pantry works great. If stored well, they’ll last for several months.
