Full details
Thompson & Morgan Spring Onion 'Lilia' is a versatile, dual-purpose onion variety ideal for home gardeners, allotment holders, and patio container growers who want a reliable, flavorful crop. The primary benefit of this variety is its ability to be harvested early as a salad onion or left to mature into a maincrop bulb with excellent storage potential. A key caveat to keep in mind is that while it is easy to grow, it requires consistent watering and well-drained, fertile soil to reach its full potential.

Troubleshooting
Slow or stunted growth
Ensure the soil is not waterlogged and that the plants are receiving at least 6-8 hours of direct sunlight daily.
Onions are bolting (flowering) too early
This is often caused by irregular watering or extreme temperature fluctuations. Keep the soil consistently moist.

Setup, Compatibility & Care
To ensure success, sow seeds 6mm (0.25in) deep in rows spaced 15cm (6in) apart. Because this variety does not require thinning, you can sow thinly and let the plants develop naturally. Ensure the planting site is in full sun, as limited light will result in stunted growth. Soil preparation is critical; incorporate organic matter into your soil prior to planting to ensure it is fertile and free-draining. Maintain consistent soil moisture throughout the growth cycle. For an early spring start, seeds can be sown in autumn and overwintered in protected areas. Once the plants reach the desired size, harvesting can begin in as little as 6-8 weeks.
