The collection consists of two of the best heat treated onion varieties.

Cupido - A recent introduction that is becoming increasingly popular amongst commercial growers. Giving a high yield, it produces consistently round onions with an attractive golden yellow colour. With a perfect slightly sharp taste and crispness this variety will keep you going right through the winter as stores well.

Red Baron AGM - The best red-skinned variety, the attractive, crimson-skinned bulbs when sliced reveal contrasting red and white rings, making it most attractive on the plate. Red Baron has a lovely, robust flavour and is a remarkably good keeper. The perfect partner for Cupido.

Heat treating our onion sets is rather like turbo-charging them! This totally natural process takes several months, but the process means they establish and grow very rapidly, giving higher yields - and with virtually no risk of prematurely running to seed or 'bolting'.

All of our bulbs are certified as disease and virus free.

Delivered in 250g packs, each pack containing approx. 70 sets.

FAQs

What are heat-treated onion sets?

heat treated onions sets is rather like turbo-charging them! The totally natural process takes a few months but improves the yield, helps them establish faster and virtually guarantees there is no risk of them running to see early or “bolting”.

What is the difference between fresh and cured onions?

When cured properly, the onions’ skins protect them, allowing them to be stored for long periods of time. If they are fresh, they will quickly go mushy and rot. To cure your onions, put them somewhere warm and dry after harvest with good air flow to let them dry out a little. Ideally, the stems should be below the bulb while storing.

Can I plant onions in September?

It is possible to sow overwintering varieties of onion in September; however, most onion sets should be sown in either March or April in the UK. Both Cupido and Red Baron AGM heat-treated onions should be sown in spring.
