WHY GROW THEM?
Easy and fast- growing, spring onions are also very versatile. They make a great addition to the veg patch, work well squeezed in between ornamental plants in a herbaceous border and are very happy in containers. Just make sure they have some sunshine and are in well-drained soil.
WHEN TO SOW?
If you want to be able to enjoy fresh spring onions over the summer, start them off in April and sow every three weeks. There’s no need to start seeds off in small pots, pop them in a prepared channel about 2cm deep – you can make this with the edge of your trowel. It’s important to rake the soil first, removing any weeds, so that it’s a fine, crumbly texture and the seeds can settle into the soil rather than falling in between large lumps.
WHEN TO HARVEST?
Ready in just eight weeks. You’ll get small, but deliciously sweet, crops if you sow in July. Sow in August and September to overwinter for early spring pickings.
‘White Lisbon’ is a crisp, tasty traditional variety but for something a bit different, Sarah Raven recommends ‘North Holland Blood Red’ for its flavour, looks and excellent value for money,as it will bulk up to the size of a red onion if left in the ground.
