Features Quick facts

White onion Rijnsburger 4 has beautiful round, straw yellow onions, which have an excellent storage capacity. When the leafage starts to die, the onions should be harvested. The onions have to dry out well before storage. The onions can be stored until spring, provided that they are kept cool and dry. The thicker ones should be kept apart and eaten first.

Tip: placing plants with a strong smell, such as camomile, savoury and carrots in the proximity of the onions ought to have a disturbing effect on the onion fly.
