When ordering some Ailsa Craig onion seeds I was only able to get 1200 seeds at a time. Much more than I'll ever use though I will put some seeds directly into the garden for green onions. If anyone would like to try some, just pm me your address and I'll send out 25- 30 seeds. Don't worry about postage, I have plenty of discount postage laying around. Might as well get rid of them, I don't think onion seeds are as viable a year or 2 later.
It might be getting a little late to start onion seeds in flats, but still might work up north.
Note that Ailsa Craigs are for northern latitudes as a long day onion. Thx
