As you can see from the photo I posted, quite a spread of young weed has come up on the section of my plot that couldn't be covered by the manure delivered. I decided to give a small section a good thick layer. My question is: would the young weed growth be viable as a green manure, and if it is, how would it be best to go about it. I am thinking that just digging it in would not be any good as my limited experience tells me that the roots would grow again and I'd be back to square one. Your help is always appreciated by me.
