The top 2 inches of my new allotment is choked with Twitch (couch
grass?)...I had the idea of skimming it off and putting it into a compost
bit then, if it grew I would treat it with weed killer (Round Up) to kill
it off...Is this a workable idea and will it turn into
decent compost ?

I have finally rid my front garden of twitch by digging every last piece of
it out, every tiny root left will explode into growth. It's only taken me
20 years ;-) I don't like to use chemicals as I have an organic garden.
I would not risk it on my compost heap. I burn the b*gg*r in my
incinerator.
