Frequently Asked Questions

What’s the most common sweetpotato (Ipomoea batatas) problem with leaves and vines, and how can I fix it?

Sweetpotato leaf beetles and spider mites commonly show up as stippled or bronzed leaves and can be worse in hot, dry weather. Spray the undersides of leaves with an insecticidal soap (spider mites) or an appropriate labeled product for beetles, and remove heavily infested vines early to slow spread. Keep the bed evenly moist during growth and don’t over-fertilize with nitrogen, which makes tender foliage more attractive.

How often should I water during the main growing phase of Ipomoea batatas?

During active vine growth and bulking, keep the soil consistently moist but not soggy—typically about 1 inch of water per week, adjusted for heat and rainfall. Water deeply so the moisture reaches below the root zone, then let the top 1–2 inches dry slightly before watering again. Overwatering can reduce oxygen to developing storage roots and invite rot.

How do I know when my Ipomoea batatas (‘O’Henry’) is ready to harvest?

Harvest at about 90 days from planting when vines begin to yellow and new growth slows, and the storage roots fill out the row. Carefully dig one or two sample roots first—sweetpotatoes should be sized and firm with skin that doesn’t rub off easily. Harvest before light frosts; after digging, cure the roots in warm, humid conditions for about a week to improve sweetness and storage.
