Growing Tips:

  • Keep soil consistently moist during early growth, but avoid overwatering or waterlogged conditions.
  • Reduce overhead watering where possible to minimise fungal diseases and leaf problems.
  • Apply a balanced fertiliser during active growth to encourage strong bulb formation and healthy foliage.
  • Keep beds weed-free, as onions compete poorly with weeds for nutrients and moisture.
  • Reduce watering as bulbs mature and tops begin to fall over to improve curing and storage quality.

Harvest:

  • Days to Maturity: 110–140 days
  • Harvest when tops begin to yellow, soften, and naturally fall over.
  • Lift bulbs carefully and allow them to cure in a dry, shaded, well-ventilated area before storage.

Growing Instructions:

  • Prepare garden beds by loosening soil deeply and incorporating compost or well-rotted organic matter.
  • Sow seeds thinly in rows or seed trays, keeping seedlings evenly moist during establishment.
  • If transplanting, sow 8–10 weeks before planting out and harden seedlings off before moving outdoors.
  • Thin seedlings early to avoid overcrowding and encourage larger bulb development.
  • Store fully cured onions in a cool, dry place with good airflow for best shelf life.
