Onion Santero F1 Seeds

Sow indoors, January-April, for larger bulbs, 0.5cm (¼") deep, in a tray of seed compost. Water well and maintain a temperature of 15-20°C (60-68°F). Keep moist. Transplant, 5cm (2”) apart, to other trays when large enough to handle. Gradually accustom young plants to outside conditions (avoid frosts), before planting out 23cm (9") apart, during April-May. Or outdoors: Sow thinly in April, where they are to crop, 1.5cm (½") deep, directly into finely-prepared, well-dug, fertile soil, which has already been watered. Allow 30cm (1') between rows. Seedlings usually appear in 14-28 days. Thin plants to 23cm (9") apart. Transplant thinnings. Harvest: August-September. Allow onions to dry, before storing in a cool, dry room.
