Winter onion sets are ideal if you want to start the season early. At Kesselaar BV, we select varieties that are winter-resistant and continue to grow well in spring. We focus on consistent size, firm quality, and minimal loss in the field. Thanks to our experience with cultivation and storage, we know what it takes to reliably supply winter onion sets. By working with fields in different growing regions and using irrigation where possible, we minimize risks and maintain a stable supply. This way, you get onion sets you can rely on.
