I'm sure you've had this problem at one time or another. It seems the more you pull it
that the more it grows. This is nutsedge the lime colored grass that grows  quite a bit
faster than your good grass and starts showing up usually in June and drives you crazy
until the first frost.

We have a product that can kill the nutsedge. It is only capable of killing what is present
at the time of treatment. Multiple treatments could become necessary in some situations.
