I have used green manures for a no of years; i sow the usual ones like hungarian grazing rye, mustard etc. I read an article and in this there was discussion of using other plants as green manures such as woad (which would have to fit in with crop rotation) and winter puslane. i think these would be good to grow as a manure and would be multi purpose, woad being a dye and purslane edible.
Do any of you have any tips and advice on alternative green manures to grow?
