April–July for the described SerpentSow directly in the final position; let plants flower, then pick young pods.
- Germination and temperature
- Use the germination requirements for the species and seed offered; there is no shared temperature for this group.
- After emergence
- Keep the seed row identifiable, moist and weed-free. Give any tray-grown seedlings enough light after emergence.
- Pricking out and potting on
- Thin a direct sowing according to the growing aim. For raising in pots, follow the supplier’s instructions and keep the root ball intact.
- Hardening off and planting out
- Direct-sown plants stay in place. If the packet says to start in pots, acclimatise them gradually before planting out.
Rat-tail radish is a pod vegetable in the kitchen: you pick young seed pods, not the root. The sowing time shown follows Serpent from Kokopelli; check your own selection.
