Red Baron Onion Seeds

[180 days] A mid-late maturing variety, Red Baron onions produce firm, globe-shaped bulbs with a beautiful, blood-red skin and red-rimmed flesh inside. It has a stronger flavour than most varieties, and works well in just about any dish that relies on onion as a key part of the flavour. When planted early, the bulbs can come out quite large. Their strong skins lend towards their excellent keeping abilities, and stored properly they should last you until it’s time to harvest your next crop.

Common Questions

Do Red Baron onions grow above the ground? The bulb of your onions grow under the soil, which is the edible part of Red Baron. Above the ground you will always see the onion tops.

How long does it take Red Baron onions to grow? Red Baron onions can take up to 6 months before maturing and ready for harvest.

How do I know when Red Baron onions are ready to be harvested? You know your red onions are ready for harvest when the bulbs are big and their tops begin to turn yellow. Harvesting is easy by pulling them up and shaking off the excess soil. Lay them out to cure with the tops still attached.
