Mustard green manure

Product Description To be sown from March to October. Use 100g of product for approximately70m. This is a vigorous plant which develops well. Mustard as a green manure is particularly useful in the fight against roundworm, but it will add organic matter and suppress weeds. Cut back at the start of flowering (about 40-50 days after germination) and after a couple of days, dig that into the soil.
