Quick answer
Onion 'Red Marksman' is a late-planting red onion that stores exceptionally well. Start seeds indoors in late winter, transplant in spring, and harvest in late summer for a sweet, crisp crop.
Why choose 'Red Marksman'?
This variety stands out for its long storage life and sweet, fruity flavour—perfect for salads and stir-fries. Unlike many red onions, it can be planted later in the season and still produce a good harvest.
Growing steps
- Sow seeds indoors: Sow seeds 6–8 weeks before the last frost date in seed trays filled with quality seed-raising mix. Cover lightly with mix and keep moist at 15–20°C. Common mistake: sowing too deep or letting the mix dry out delays germination.
- Harden off and transplant: Once seedlings reach 10–15 cm tall and frost risk has passed, gradually acclimate them to outdoor conditions over a week. Plant 10 cm apart in well-drained soil with full sun. Checkpoint: space rows 30 cm apart to allow bulb development and airflow.
- Water and weed regularly: Keep soil consistently moist but not waterlogged. Mulch with straw to suppress weeds and retain moisture. Onions have shallow roots, so avoid deep cultivation near the plants. Common mistake: overwatering or allowing weeds to compete for nutrients.
- Harvest and cure: When the tops yellow and fall over, gently lift bulbs with a fork. Cure in a warm, airy spot for 2–3 weeks before trimming tops and storing in a cool, dry place. Checkpoint: do not wash bulbs before curing—dirt protects the outer skin.
