Growing Brussels sprouts

25 Jan 25 Coco's Garden (USA - Zone 8a climate)
It's not you!! Zone 6a is a tricky (difficult?) climate for Brussels IMO. Waiting for the right temp to plant in spring means it will be too hot for them, come harvest time. The reverse is your issue in late summer/fall, although you have a fighting chance. Plant approx 5" starts around 4th of July. Protect from white cabbage butterflies using lightweight floating row covers. Protect them from extreme heat (using shade cloth). Later, monitor fall temps. Cover with blankets if temps go below 20F. They will survive temps as low as the high teens (and even as low as 10 for brief periods). I have moved from your zone to 8A, where I plant my 5" starts mid Sept and I harvest my sprouts in Feb and March. Meanwhile!! You have an ideal hardiness zone for garlic, while I have to do backflips bc it's a bit too warm here. Your hardiness zone makes all the difference!
