2 years ago I winter-sowed some multiplying onion seeds in an old meat tray about an inch deep with soil. I just sprinkled them on top and tamped them down with my hand. They came up and then in the early spring I transplanted them into the garden intermingling them with catawissa onion sets. They are still out there and still multiply. They were really easy to grow.

I direct seeded them in the garden some years back and each spring dig up a few clumps and line them out in a new spot.
