Am growing mustard to dig bach into the soil. My question is at what stage of plants should I pull and dig in. They have not yet flowered.

dig in before they flower

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?
