Onion 'Snowball'

Snowball onion sets are large, round bulbs for planting in spring or autumn. They produce a reliable crop of mildly flavoured white onions ready to harvest in summer.

These allium bulbs are essentially baby onions and are much quicker and easier to grow than onions from seeds. Prepare the ground in advance, adding plenty of organic matter for extra nutrients. Choose a sunny spot with well-draining soil and plant the sets 15cm apart, leaving 30cm between rows. Ensure the noses face upwards and position the bulbs 2-5cm deep, lightly covering with soil. Keep the area free of weeds and water regularly during dry spells. Keep an eye open for any flower stems and remove them as soon as they appear. Doing this helps prevent the plant from bolting and ruining the crop.

Snowball Onions are ready to harvest a couple of weeks after the foliage turns yellow. Use a garden fork to gently lift the swollen bulbs and leave them to dry out for around a week. After this they can be stored in an onion bag or hung up in a dark, ventilated place. Stored properly, white onions are good to eat for around 8 months post-harvest.
