Well, where I am it's gardening zone 5. Winter temps usually in the 20s and 30s, though the teens are common, single digits happen, and below zero maybe a couple days every few winters or so.Really, normanack? This has my full attention. How cold do you get and how much snow? We're a couple of states west of you in northern MN. I have been thinking about overwintering kale but didn't think it could take our winters. We grow Swiss Chard, too. Would think that may not be quite as hardy. Interested to know where you got your seeds, etc. Thnx
Snow -- varies by the winter. Often no snow before Christmas, but if it snows in January it tends to stick around. February is miserable, icy when it's not snowy.
The kale gets buried under the snow. It seems unaffected by freezing. Now, it's not actively growing that I can see, but whatever is there in the fall is usually still there and looking quite edible in the spring. A woodchuck ate ALL the chard this fall so I won't have any of that. As I recall it's excellent right through Christmas and some is still there looking good in spring.
Seeds? The cheapest I can find, hardware store or Wal-Mart or the supermarket. I used to buy Johnny's Selected Seeds and Pinetree Garden Seeds by mail, years ago, and they were great, but I'm not good at planning ahead, and money is tight.
