I am starting to think and plan out my fall/winter garden. I am looking at trying to plant some crops that will be overwintered and some crops that I can harvest before spring. What special steps should I take to prepare my beds for fall and winter crops that are different than what I do for spring crops? This year I pretty much just tilled up my soil and did not worry about soil amendment or anything. Can I do this for fall and winter crops as well or do I need to take more care with these plants?
I'm not totally certain what I am going to plant yet and I know some of this will depend on that, but I know I will try onions and garlic, and probably some carrots, radishes and maybe some leafy greens (maybe spinach and lettuce).
