Winter sowing is an easy way to start seeds outdoors using natural freeze–thaw cycles. These varieties thrive in Zones 3–8 and can be sown in containers and left outside to sprout in spring. Zones 3–5 sow from late December to March, Zones 6–7 sow from January to March, and Zone 8 sow from late December to February. Plant them in a vented container, set outside, and let nature do the work.
Grew these for the past three years and I will keep growing them for many more. I highly recommend them. Great germination rate. Every onion grew to the size of baseballs and others a bit bigger and they store very well.Best long day onion I have ever grow.
I am very happy with my heirloom seeds. I cannot wait to germinate them.
Started my seeds on 12/31/25. I’ve had almost 100% germination and the onion seedlings are a couple of inches tall at this point (1/9/26). Looking forward to a great harvest!
