Green Manure

If you have bare ground now, or will be soon it could be a good idea. Green manure is usually something that sprouts quite quickly and produces plenty of green leaf that is dug in before and seeds are allowed to set. SO not suitable if you were no dig really. so depends what seeds you have. The brassica tribe could be good but you would need to be aware of using then in any crop rotation scheme you are using.
