Onions are one of the easiest crops to grow. They have few pest issues, they don’t take up much room and they can be grown anywhere in the garden where there is well-drained soil and full sun exposure.
What are onion sets?
An onion set is simply an onion grown from seed which has not been allowed to grow to its full potential. Our growers plant onion seeds very close together so the resulting onions grow very small because they are so crowded. They are then lifted and stored ready for replanting in your own vegetable garden / allotment.
When can you plant them?
Onion sets can be planted in either autumn or spring. Planting in autumn will give your sets a great head start for the coming harvest and they will reach maturity up to a month early. They can be used for freshly harvested spring onions too!
How long do they last when harvested?
There are a thousand different varieties which all have different storage qualities. Brown onions hold out the longest, red onions are good for a few months but sequential planting is best if you want a continuous supply. Estimated storage times can be found on the product pages on our website.
Why sets over seeds?
Growing from seed is the most economical way to grow onions but germination can be slow and patchy, leading many gardeners to start them indoors in early spring in order to ensure a full harvest later in the year.
Onion sets are the easiest way to plant and ensure a harvest of full-sized onion bulbs. They are ready to plant and won't take up valuable space in your seed trays clogging up your greenhouse early in the season.
