Spring onions are one of the easiest ways to get a genuinely useful harvest from a very small patch of ground.
Spring onions are a quick, undemanding crop, best sown in short successional rows so you’re never left with a glut. Left in the ground too long they bulb up and lose the mild flavour that makes them useful raw.

Sow in short rows every few weeks for a rolling supply.
- Harvest May – October
Pull while still slim — left too long they bulb up and lose their mild flavour.
Growing tips & common problems
- Sow thickly in short rows rather than trying to space individual seeds — they're pulled while still slim anyway.
- Keep the bed weed-free; their thin, upright leaves compete poorly against anything bushier nearby.
- Pull while young for the mildest flavour — left too long, they bulb up and turn sharper.
