Crowing
Thank you. I’m still trying to figure out how to best use this greenhouse. I built it for my wife when we moved to this house. She mostly wanted it to get an early start on flowers and veggies. I just figured since it was sitting empty I would try out with some leftover seeds.Timing is everything! Figuring out the right time to start the seeds /transplants is key to winter gardening in a cold greenhouse or under row covers here. They have to be well started before the real cold weather arrives. You will figure it out and be successful! What you can grow successfully under cover that far north is the question. Some northern growers I know use row covers inside an unheated greenhouse or two layers of row covers in extreme weather all the way up in Vermont and Maine. I am not sure what they are successful with. I see collards, kales and even spinach and over wintering carrots mentioned sometimes. Your state AG. extension service should be able to help you with crop suggestions for your area. Very few seeds will germinate reliably in cold weather even in the fall before winter, so starts are the way to go on most unheated fall plantings, with some exceptions possibly.
