How to grow spring onions
Seed Sowing
Sow your spring onion seeds from January through September. Ideal for direct sowing from March onwards or indoor sowing in modules from January. Sow seeds no deeper than 1 cm for successful germination. Well-suited for successional sowing.
Transplanting
Ensure a weed-free seedbed. Directly sow seeds in rows around 10 cm apart; thin out later to 2-3 cm. Young plants are ready in 4-5 weeks. Plant them 25 cm apart in rows or clusters. Keep the soil well-watered.
Plant Care
Spring onions are easy to care for. Keep them weed-free and hoe regularly. They prefer free-draining, rich soil, but excessive richness may lead to more top growth.
Challenges
Allium Leaf miners and onion flies are potential pests. Remove leaf miners promptly. Protect from onion flies using insect mesh to prevent egg laying on young alliums.
Harvest
Spring onions should be ready around 12 weeks after sowing. Harvest the whole plant gently with a hand trowel to avoid bruising.
Culinary Ideas
Extremely versatile, spring onions are delicious cooked or raw, adding flavor to various dishes as a cooking ingredient or garnish.
Seed Saving
To save spring onion seeds, grow at least 50 plants for genetic diversity. Isolate from other alliums. Harvest seeds when the casing turns papery. Dry seed heads for 10 days, rub off seeds, and store in a cool, dry place for up to 2 years.
Growing suggestions for spring onion seeds
Sow spring onion seeds in drills as close as 10cm apart in well prepared, weed-free soil. Seeds can be 2-3cm apart in the row with no need to thin. For a very early crop seeds can be started indoors in January. Spring onions can be sown throughout the growing season. For a continuous supply of pencil-thick onions we recommend sowing every two weeks. They are ready for harvest six weeks after sowing.
Crop history
Also know as green onions and scallions, spring onions describe a long, thin allium with a distinctive mild, oniony flavor which is eaten as a whole, including bulb and leaves. They come from two different kinds of plants, bunching and bulbing onions.
References to spring onions and chives occur in Chinese records dating back over two thousand years. The Egyptians, Greeks, Romans and Chinese all planted and used this vegetable. Spring onions earned their name from their early appearance in the spring after the cold months of winter when every green colour is welcome.
