[Swing Swang]

Rake and hoe - in future years do it before it sets seed and you'll get on top of it in 7-8 years

Provided there are no other 'nasty' weeds in the area, I dig chickweed in as a sort of green manure too.

There are two sorts of chickweed, one of which can root off a cut stem, not just propagate from flowers.. These low ground cover weeds are potentially good green manure and I certainly try my best to incorporate as much as I can. But they are always a long term management issue.
My ever present weed of that type is speedwell, and apparently it can replicate from bits of root just like bindweed. I didn't know this until a couple of years ago, and had always wondered why it kept returning. I know now. I certainly wouldn't rotovate speedwell or any similar low creeping weed like chickweed. These weeds are tempting as a green manure but safer to compost properly first, or at least turn by hand.
