Harvest

  • A top-performing red onion variety chosen by our experts
  • Great value for money
  • High yields of great-tasting bulbs
  • Delicious in salads, sauces and curries
  • Let our experts do the work for you!

Want to grow your own onions but not sure which variety to choose? Let our experts do the work for you! Our Growers Pick Red Onion Sets have been specially selected by our experts for excellent flavour and all-round performance. Each pack contains 65-75 sets of the same variety.

With a stronger flavour and thicker skins than white onions, red onions are great for sauces and can also be eaten raw in salads, where their bright colour adds extra interest. They’re particularly good for making curries!

Our growers will choose your sets from our range of top-performing red onion varieties. While we can’t specify which variety will be chosen, you can be sure of receiving high-yielding, great-tasting red onion sets at great value for money.

How To Grow

Prepare your soil: Onions, Shallots, and Garlic prefer an open, sunny site and light, free-draining soil. If you have heavy soil, dig in a generous amount of grit and organic matter into the planting area to aid drainage. Avoid planting them in very heavy or freshly manured soil. Onions are sensitive to acidity, so if you have acidic soil add some Garden Lime to the area well before planting or use our Concentrated Slow-Release Onion, Garlic & Shallot Feed Granules when planting.

Planting: Both Autumn and Spring varieties can be planted straight out into your pre-prepared soil. Loosen soil and dig in some of our Concentrated Slow-Release Feed Granules to add essential nutrients for optimal growth.

Onion & Shallot Sets: Plant Onion and Shallot sets (pointed end upwards) with the tips of the sets showing at the soil surface. 

Onions: These should be spaced 5-10cm (2-4in) apart with 25-30cm (10in to 1ft) between rows. 

Shallots: Should be spaced 15-20cm (6-8in) with 30-45cm (1ft to 18in) between rows. 

Garlic: The Bulbs should be separated into individual cloves and planted pointed end up, so that the tip of each clove is 2cm (1/2in) below the soil surface. Leave 15cm (6in) between individual cloves and 30cm (12in) between the rows. We also recommend covering garlic bulbs in Horticultural Fleece to protect emerging shoots from hungry birds!

 

Guide To Plant Sizes

What to expect when they arrive: Our sets and cloves are suitable for planting out immediately. However, if you’re unable to do so right away, we recommend keeping them in a cool, dark place until you are ready. Sets are sold by weight, so counts may vary slightly to those stated on our website.
