    I once went to a vineyard in Norfolk and they told us that they used yellow rattle to keep out the couch grass, I thin it stops it spreading.

    Worth a try but I'd weed the big plants out first and use the yellow rattle to weaken the inevitable new ones that come.  I too have couch grass rampaging about no matter ho well I weed my borders so may well give the rattle a try.

    Good idea.
