Product description

Why choose our first-year organic red onion sets? Because we grow them ourselves, we know our varieties in detail. Only varieties that meet our strict criteria are included in our cultivation program. This guarantees:

  • Top-quality onion sets
  • Optimal growth performance on various soil types
  • Reliability and uniformity in yield

Unique cultivation locations ensure guaranteed quality

We distinguish ourselves through geographically distributed cultivation. This limits risk and ensures stable quality:

  • We are the only grower in the sector to cultivate on pristine, disease-free plots in Northern France.
  • We carefully select plots in Southwest Netherlands and the Flevopolder region, in collaboration with our cultivation specialists.

Our crop managers closely monitor growth using a specially developed cultivation program tailored to the unique conditions of each growing region.

Selectplant certification: assurance for your onion crop

Our organic red onion sets are certified with the independent NAKTuinbouw Selectplant quality mark. This offers additional assurance beyond the European standard:

✔ Free from downy mildew (Peronospora destructor)

✔ Free from white rot (Sclerotium cepivorum)

✔ Standard testing for stem nematodes (Ditylenchus dipsaci)

By cultivating on plots free from these soil-borne diseases, we ensure a healthy and trouble-free start to the growing season.
