I did this twenty years ago with giant red mustard. I always let a few plants on the edges go to seed, and strew the seed. I still have volunteer red mustard, and so can add some young leaves into a salad if I wish, but also benefit from the chemicals it produces when dug in to the soil to deter nematodes. Dig it in whenever you are ready by the way !

Started growing some years ago and they now come up all over the vegetable garden. But why is it suggested that it not be grown with some other vegetables?

Any supermarket in the spice section will do.

I use bok choy a lot, which may be cooked in similar ways. Usually: wash the leaves, shake or pat dry, shred leaves, lightly sauté in olive oil with some chopped garlic and/or ginger, add a small splash of liquid (something acidic like lemon juice, ver juice or left-over wine, a dash of mirin and tamari or fish sauce), cover and steam over moderate heat for a few minutes.
