I have some clumps of a very coarse rough grass invading my lawn. Each
clump is about 2" (5cm) to 10" (25cm) in diameter, and is composed of
hundreds of grass 'plantlets'. This is on a heavy clay soil in Essex, UK.
I have controlled it by pulling it up, but it comes back after a season.

A photograph of a grass plantlet can be seen here
http://ucosm.tripod.com/photos/grass6.jpg (21KB). The plantlet
photographed measures approx 4" (10cm) from root to leaftip.

Can anyone identify this grass, and offer any advice about removing it?

TIA
Susan

thats called Quack Grass
