Heirloom Onion Seeds
Harvesting Onion Seeds
Farmers and gardeners often grow onions from sets or small bulbs, but growing onions from seed results in better-quality onions that are less prone to disease. Onions flower and form seed in the second year of growth, and bees cross-pollinate them. To preserve the purity of a certain strain for seed saving, make sure your different varieties don’t flower at the same time, or keep them separated by at least 100ft. This will reduce the likelihood of crossbreeding.
Dig up your best onions in the fall of the first year and store them in a cool (32-40 degrees), dry place over winter. When the ground can be worked in the spring, replant your onions 3-4 in. apart, covering the bulbs with .5in. of soil. Make a cut in the top of the onion before replanting it, to help the seed stalk emerge more quickly.
Harvest onion seeds by cutting off the seed heads, drying them for several weeks, and rubbing the seeds off with your hands. Onion seeds ripen gradually but flower heads shatter easily, so be sure to watch them closely. Onion seeds are harvested BIENNIALLY.
