How to Grow White Lisbon Spring Onions
Sowing
Make early sowings into shallow drills in a cold frame or under cloches between February and April. Later in the season, between May and July, you can sow directly into the ground.
Growing
There is no need to thin, simply remove cloches by mid-April and as they grow, pull every other onion to allow those still in the ground to continue growing. Water freely during dry weather and feed the plants with high-nitrogen feed as soon as the leaves start to develop and again 5 weeks later. White Lisbon spring onions can be grown in between slower-growing vegetables as they are in the garden for a short time.
Harvest
They can be harvested between May and October, when the stems are long and white with bright green tops. It’s ideal for successional sowing for all summer crops. For a continuous supply, sow every 2-3 weeks. White Lisbon spring onions grow best in cooler weather with optimum soil temperatures for germination between 4-24°C. Keep soil moist during germination in dry weather.
