I have searched the internet far and wide to try and figure out what this is. It seems to grow in clumps and straight up. The roots are thin and long and go straight down in the ground. Its very annoying because it seems to grow four times as fast as my St Augustine. Can anybody tell me what this is or point me in the right direction. I thought it was crabgrass at first but i'm pretty sure its not. Any help or guidance is appreciated! I'm at wits end with this stuff! I have other pics if needed.
