Product Description

Onion ‘Brown Odourless’ is a dependable intermediate-day variety grown for its large, uniform brown bulbs and mild flavour. Unlike stronger pungent onions, this variety offers a sweeter, gentler taste that works beautifully in salads, sandwiches, roasting, soups, and everyday cooking without overwhelming dishes.

Its smooth brown skin, firm globe-shaped bulbs, and strong storage ability make it a favourite among home gardeners and growers looking for both flavour and practicality. Once cured correctly, bulbs store well for months, making it an excellent choice for long-term kitchen use.

This variety performs best when sown during the cooler months and thrives in fertile, well-drained soil with consistent moisture and full sun. It is easy to grow, productive, and highly reliable across most Australian growing regions.

Growing Tips

• Prepare the soil well before planting by loosening deeply and adding compost or aged organic matter.
• Keep moisture consistent during early growth, but avoid overwatering once bulbs begin to mature.
• Avoid overhead watering where possible to help reduce fungal disease and leaf problems.
• Keep beds weed-free, as onions compete poorly with weeds for nutrients and moisture.
• Feed with a balanced fertiliser during active growth for strong bulb development and better yields.
• Reduce watering near harvest time to allow bulbs to cure properly and improve storage life.

Harvest

Harvest in approximately 110–140 days when the tops begin to yellow, soften, and naturally fall over. Lift bulbs carefully and allow them to cure in a dry, well-ventilated area for 1–2 weeks before storage.

Companion Planting

• Carrots: Excellent companion that helps repel onion fly while onions help deter carrot fly, creating strong natural pest protection.
• Beetroot: Uses garden space efficiently without heavy competition and supports healthy soil structure.
• Lettuce: Fast-growing crop that makes good use of space between slower onion rows.
• Chamomile: Encourages plant health and attracts beneficial insects.
• Parsley & Thyme: Helpful herbs for improving biodiversity and supporting pest control.

Growing Onion ‘Brown Odourless’ alongside carrots and beetroot creates a productive, low-maintenance garden system that improves soil health, reduces pest pressure, and supports strong, healthy bulb development throughout the season.
