About Bok Choy

Bok choy is an Asian brassica that grows fast, tolerates light frost, and produces tender crisp leaves for stir-fries and soups. A reliable cool-season performer with two growing windows per year.

Start indoors 4-6 weeks before last frost or direct sow in fall. Harvest outer leaves continuously or cut the whole head at 2 inches above soil for regrowth. Keep moist — dry conditions trigger bolting.
