Frequently Asked Questions

What’s the most common pest or disease problem for sweet potato (Ipomoea batatas) in the home garden, and what should I do?

Watch for sweet potato weevil and/or stem/root rot issues that show up as wilting vines and soft, decaying storage roots. Check the stems weekly and remove any visibly infested plants, then rotate where you grow Ipomoea batatas each season. If vines collapse or roots are soft, dig up affected plants promptly and discard them; don’t compost diseased material to reduce spread.

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

During active vine growth, keep the soil consistently moist but never waterlogged—aim for evenly moist beds about 1–2 inches deep. Water deeply when the top inch starts to dry (often about once per week, but adjust for heat and sandy soil), then reduce slightly once vines begin to thicken so roots don’t rot.

How can I tell when ‘White Delite’ sweet potatoes (Ipomoea batatas) are ready to harvest?

Harvest at about 90 days after planting, and only after foliage begins to yellow as roots mature. Before digging, gently scrape a bit of soil to confirm tubers have filled out and set a smooth skin; mature storage roots should feel firm and well-formed. Lift carefully with a digging fork to avoid bruising, and cure harvested roots soon after harvest to improve sweetness and storage quality.

Silken-smooth flesh with a luminous, creamy-white glow defines White Delite—sweet, gently fragrant, and wonderfully mellow in flavor. The roots form with an elegant, tapered shape and a tender, fine-grained texture that bakes up silky and caramel-kissed, while also shining when sliced for fresh, crisp-leaning preparations. Grow White Delite for a standout white sweet potato harvest at about 90 days, perfect for showcasing its delicate sweetness in every garden-to-table moment.

Sowing Tips

Transplant Conditions

Wait until soil reaches 65°F and nights stay above 55°F before moving outdoors. Harden off for 10 days first.

Direct Sow Preferred

Sensitive roots — does not transplant well. If starting indoors, use biodegradable pots and disturb roots as little as possible when moving outdoors.

Expert Note

Plant only after soil is thoroughly warm (and night temps stay above ~55°F); sweet potatoes usually do best when slips are transplanted rather than seed-started.
