The Reject Shop sells seeds - I bought Mustard Greens seeds for only a couple of dollars and they grew fantastic!

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?

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.

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 !

A friend just told me you dig them in just before they flower, If that helps, Frank.

This Autumn and Winter I scattered mustard seeds around the place - a biodynamic book said to do that. When I'm weeding I see a nice mustard green I just eat it on the spot. Leave some patches to grow bigger and eat them chopped up in your dal/lentils - stem & all. Keep sowing them all the year.
