Sow seeds direct or raise seedlings in a protected area (in a greenhouse or indoors). Sow seeds approximately 5 to 6mm deep. Keep soil moist. If raising seedlings, transplant out when seedlings are around 6 to 10cm tall. Start seeds in autumn and winter*. Germination occurs within 7 to 10 days, at an ideal temperature of 20 to 25°C. Leave 10cm between transplanted seedlings or sown seeds, and approximately 30cm between rows of Brown Spanish Onion. Brown Spanish Onion reaches full maturity after around 180 days.
*Sowing times may vary depending on your climate. See our planting guide for Brown Spanish Onion below.
