I believe I have the OgrassO clumps. What weed killer will work to get be rid of them.

Nope, no seed head and much shorter in stature.. but many thanks for being the one reply!!!! Really. Thank you.

Could it be nutgrass? If so it can grow through swimming pool liners. I recently read that it was edible.

Advance thanks to anyone who may discuss this topic; this has stumped many ÒexpertsÓ and become the bane of our once green lawn. The images above were taken in March of this year, in an area where only weeds were growing. Once dormant, the low, round, hairy clumps of ÒgrassÓ leave behind brown, dormant areas so thick with ÒbulbÓ and root matter that no other grasses can take hold and grow. This tiny monster lays lawns low, leaving a veritable wasteland in its wake. This invasive plant is crowding out all other desirable lawn and because we canÕt identify it, digging it up has become the only method possible. To date, we havenÕt used weed killers and would prefer not to, but identification of this plant would answer much strife and stress spent in its pursuit. Please answer our prayers, oh Lawn Gods and Goddesses?
