Slips to cured roots

Start slips

Sprout from a root

Sweet potatoes grow from "slips" β€” shoots sprouted off a store or saved root in water or damp soil.

Love the heat

Warm soil, long season

They need warmth and a long season β€” plant after all frost into warm soil and give them ~100 days.

Loose, lean soil

Don't over-feed

Loose, well-drained soil and modest feeding. Too much nitrogen grows vines instead of roots.

Cure to sweeten

Warm & humid, 1–2 weeks

Cure the dug roots warm and humid β€” it heals the skin and turns starch to sugar. Then they store for months.

The flavour secret: freshly dug sweet potatoes aren't sweet β€” curing is what makes them so. Skip it and they're bland; cure them and they store beautifully and taste far better.
