Frequently Asked Questions

What pest or disease commonly affects Ipomoea batatas (sweet potato), and what should I do?

Sweet potato often suffers from sweet potato weevil (larvae in storage roots) and from root rot/fusarium problems in overly wet soil. Rotate plantings away from previous sweet potatoes and keep beds well-drained; avoid planting slips into cool, waterlogged ground. Inspect roots at harvest for tunnels/brown galleries and discard heavily infested roots rather than composting them.

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

During active vine growth, keep soil consistently moist but not soggy—about 1 inch of water per week depending on rainfall and heat. Once roots start bulking (usually mid-season), water more deeply only when the top 1–2 inches of soil dry out to prevent root rot. Stop watering about 1–2 weeks before harvest so roots cure better in storage.

How can I tell when Ipomoea batatas is ready to harvest?

Harvest at about 95 days after planting slips, or when vines begin to yellow and foliage declines. Before digging, wait for a light frost-free period; sweet potatoes are best harvested before hard freezes. Carefully dig and check that roots are sized and firm with smooth skins—if skins rub off easily, leave the bed a bit longer.

Sink your fork into Hernandez’s richly colored orange flesh, where a sweet, honeyed aroma rises with every bite. At maturity (about 95 days), the roots form with a smooth, attractive skin and a tender, velvety texture that shines in oven-roasted favorites, silky mash, and vibrant purées. Grow Hernandez for a dependable harvest that brings warm color and comforting sweetness to your seasonal table.

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

Because melons are root-sensitive, start indoors only if you can keep the soil ball intact and transplant after consistently warm nights.
