Exhibition Big Onion Seeds

With over 30 years of experience and being the original breeder of the World Record Big Onion Ailsae in 1986, I have accumulated a tremendous amount of knowledge and experience in growing big onions which I like to share with other growers.

All the Ailsae big onion seeds I sell are from the original strain and are graded at 2.4mm or above producing a high thousand seed weight (tsw) for a strong germinated seedling.

Interested in growing big onions?

Have a look at my booklet on growing large onions which has been written in an easy-to-understand no-nonsense way.
