Nettle: Sowing, planting and harvest calendar
How to sow nettles successfully under cover?
Sow common stinging nettle under cover in spring, for example in March or April depending on your climate. Use pots or a seed tray with drainage holes and moist seed compost. Scatter the tiny seeds on the surface and press gently without burying them: light encourages germination.
Put the seed tray in a bright place around 20 °C without letting it overheat in sunshine. Keep the compost slightly moist with gentle watering and no standing water. Germination may be uneven; also follow the seed packet rather than expecting a fixed time.
Transplant seedlings once they have several leaves and are large enough to handle. Harden them off gradually before planting outside in rich, moist soil. Wear gloves as soon as the plants develop stinging hairs and choose a site in advance where you can monitor their spread.
