>> Rick- would you say that the 50 days to harvest is pretty accurate for you?
I'm not that organized yet, by far. I notice if they all die, or thrive enough that I get plenty. i WOULD say that any of these Brassicas that I don't kill, are edible as salad greens in much less than two months, like microgreens in 3 weeks and salad greens in 4-5 weeks. Probably (as far as I recall) 45-60 days would be optimum harvest time for mature plants (steam or sautee).
Last spring was very cold and only Bok Choy did well, then I got busy with other things and planted NO Fall crolps. So I really can't say. But all these Asian greens are good if you have to harvest them before fully mature: tender for salad, just less yield per square foot.
