This was my first attempt to grow a Chinese cabbage, so I wasn't expecting much. I started the seeds at the end of October and planted them out the first week of November...15 of them...in the (almost) full shade. See, the problem with winter is the low sun angle. My narrow backyard is almost completely shaded from November to February, due its orientation. You guessed it: north of the house. We're talking only a few minutes of sun. But these little babies grew anyway! I harvested the first one a couple of days ago. It weighed 12 ounces. No caterpillars, no aphids, only a little dirt. And, it was great tasting!
