I planted beets on Sept. 27 because I thought the seed catalog said 30 days. When I looked again (after planting, of course), it said 50 days. However, it also said it was good to plant two weeks prior to the last frost, which indicates that the beets continue growing until winter truly sets in.
Here's how my tiny little beets look. Will they get to any size whatsoever before the snow starts flying? I have no idea. Usually we don't get a bunch of snow and really cold weather until Thanksgiving, but last year, I think we got several inches by Nov. 6.
This is the sunniest spot in my yard, so maybe I'll have baby beets for Thanksgiving!
Except that my sons probably wouldn't eat them and we are planning on having dins with the boys, so I'd better think of a more conventional vegetable for Thanksgiving.
