How to Save Seeds
Separate onions from other onion varieties by approximately one-half mile to maintain seed purity.
A preferred method for seed saving is the seed-to-seed method, where onions are planted from seed and allowed to remain in the ground through the following growing season.
Mulching with hay or straw during winter helps protect plants similarly to garlic overwintering methods. The following year, allow plants to flower and form seed heads.
Once black seeds become visible within the drying seed heads, cut and collect the seed heads. Multiple harvests may be necessary as seeds mature gradually over time.

Great
When looking for our seeds for this year, my husband and I wanted to prioritize a few things 1. Christian, 2. non-GMO/organic, 3. family owned 4. high quality. We were delighted to check every box with South Ga Seed Co. We were impressed with the variety of seeds, packaging, shipping time, and personalized note when our package arrived. We haven’t reaped the benefits of planting the seeds yet- but with the experience thus far we expect great yields!
