Well i have been having a hell of time trying to control these things. I dont really do many lawns so I have to backpack it all. But this sucker just doesnt want to die and its spreading good in all my lawns. Kinda acts like clover just tougher. Only way i have seemed to be able to kill is to dang near spray roundup on it. At least I have to spray so hot that it kills all grass around it. It looks a lot like clover. But has a woody stalk. I am thinking it might be Lespedeza but im not for sure.
