Product information
DescriptionWe grow them ourselves so we know our varieties through and through. We work closely with several of the best seed breeders and together we select the best varieties for both the professional grower and gardener. As a result, our onion sets meet the highest quality standards and only the very best varieties qualify for our cultivation program.
We grow our onion sets on virgin and therefore disease-free land in Northern France, the South West Netherlands and in Flevoland. Together with our specialists we select the best land in these areas, and because of the extensive geographical spread we can minimise risks and can deliver a high-quality product at all times.
Optimal output is achieved by the cultivation manager, supported by a team of specialists, who supervises the growth of the crop by means of a specially developed cultivation and agronomy program. Thanks to extensive knowledge acquired through years of experience, the cultivation manager and his team know exactly which soil types the onion sets thrive best on.
We follow market trends closely to ensure we retain our leading position within the sector. We do everything possible to deliver the best onion sets: premium quality disease-free sets which are full of vigour!
All of our onion sets are NAKTuinbouw ‘Selectplant’ certified, so they meet the highest possible quality standards. Information regarding the sets supplied is available and upon request. We obtain this information from systematically taken samples which are analysed in a laboratory, as well as through our own practical trials and external field trials.
During the production of the onion sets the crop is left alone to grow as naturally as possible without intervention to allow nature to do its work. For example, the sets are grown without artificial fertilisers and no chemical crop protection agents are applied. All of our organic onion sets are SKAL certified.
