Nepeta Catnip Seeds

Sow indoors, January-April, to flower the same year, 0.5cm (¼") deep, in a tray of compost. A temperature of 15-20°C (60-68°F) is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant them 5cm (2") apart, to other trays when large enough to handle. Gradually accustom young plants to outside conditions (avoid frosts), before planting out into well-drained soil, May-June, 30cm (1') apart, when frosts are over. Or, sow outdoors, April-June, to flower the following year, in a seed bed, 0.5cm (¼") deep, into finely-prepared, well-drained soil, which has already been watered. Thin seedlings to 5cm (2") apart, before planting out to flowering position in autumn, spacing 30cm (1') apart. Flowers: June-September.
