Red onion sets must not only grow well but also have a beautiful color and a firm bulb. At Kesselaar BV, we therefore pay extra attention to uniformity, health, and consistent quality throughout the entire batch. We make conscious choices regarding varieties and growing locations, taking into account cultivation history and disease risks. Thanks to collaboration with regular growing partners and regional diversification, we limit the risk of problems and maintain a stable supply. After harvesting, the onion sets are carefully stored and sorted. This allows us to deliver red onion sets with a strong foundation, good shelf life, and a neat, deep color.
