Gorgeous burgundy-red bulbs with a topknot of deep green which look fabulous on the plot or as edging to a flower or herb bed. Despite the high-class looks it's very easy to grow, and versatile too: harvest the bulbs young as slender, mild spring onions for brightening up your salads, or give them more space to bulb up for cooking. Spring onion 'North Holland Blood Red' is a good source of vitamin C.
Keep the area weed-free to reduce competition. Water regularly to maintain consistent moisture, especially in dry spells, which helps produce tender, mild-flavoured stems. A light feed with a balanced fertiliser during the growing season can encourage strong, healthy growth.
Harvest spring onions once the stems reach a usable size, usually when they are around 1-2cm (up to 1in) in diameter. You can pull the whole plant or trim outer leaves as needed for a continuous supply. Regular harvesting also encourages the bulbs to remain tender and prevents them from bolting. Mulching can help retain moisture and protect the shallow roots.

Make early sowings into shallow drills in a cold frame or under cloches: later in the season sow direct into the ground. There's no need to thin: just remove cloches by mid-April and as they grow pull every other onion to allow those still in the ground to continue growing. Naturally thin the crop during the season. Ideal for successional sowing for all Summer crop. As they are in the garden for such a short time, they can be grown in between slower growing vegetables.
