Northerners - do you do fall crops?
I was enquiring at the local nursery about getting broccoli transplants in August (our first frost is mid-Sept) and they had never heard of anyone doing that. So, that got me wondering. How common is it? Last year, I had reasonable success growing radishes in the fall (sowed Sept 5, covered with polytunnels early Oct, harvested mid-Oct) but I would like to try something else this year.
