Onion Sets - The Easy Way to Grow Onions

No seed sowing, no thinning, no fuss; just push them into the earth where you want them, and watch them grow! - Unpack sets on arrival, and spread in a light cool position until planting time. Plant February-April, leaving tips of bulbs above the soil surface, allowing about 10cm (4") between sets and about 30cm (12") between rows. 250g of onion sets (approx. 60 sets) will plant a row of about 6m (19'). Size of sets 14/21mm.

Why buy heat treated onion sets?

It's frustrating when your beautifully forming onions decide it's time to develop seed and send up a flower stalk. Heat treating is a process that we carry out on your behalf to prevent this happening.
Heat treatment starts in November depending on the size of the bulb. During the heat treatment, the onion sets are gradually heated up over 12 days from the 3-5°C storage temperature to 30-32°C and, depending on size, are kept at this temperature for 30-60 days (during which time they are heated up to 32-35°C for 10 days) and then gradually cooled to 10-14°C for planting in April/May. So whilst they are a little more expensive, you can be more confident of harvesting onions you can be proud of!


Autumn planting Onions, Garlic and Shallots will give you an earlier crop next year!

Onions are one of our most invaluable vegetables and also one of civilisation’s oldest medicines. They can help lower blood pressure and cholesterol levels, and are anti-asthmatic, antibacterial and antiseptic.
