Green Manure
Vegetable growers sometimes grow mustard as a green manure. Its main purpose is to act as a mulch, covering the soil to suppress weeds between crops. If grown as a green manure, the mustard plants are cut down at the base when sufficiently grown, and left to wither on the surface, continuing to act as a mulch until the next crop is due for sowing, when the mustard is dug in. In the UK, summer and autumn-sown mustard is cut down from October. April sowings can be cut down in June, keeping the ground clear for summer-sown crops. One of the disadvantages of mustard as a green manure is its propensity to harbor club root.

Down the green hill athwart a cedarn cover!
A savage place! as holy and enchanted
As e’er beneath a waning moon was haunted
By woman wailing for her demon-lover!”
