I have been fighting this stuff for 2 years now and its starting to get out of control. I have put down EVERY single over the counter stuff available at home depot/lowes I can find. Iv used that bayer crabgrass stuff, nutsedge, scotts turf builder with weed, numerous hose sprayer stuff, concentrated stuff... im not joking, almost every single product, I have used and this stuff will NOT die!! it almost looks like a mini st. augustine grass, but its not. it starts in little clumps and is a light lime green color... some of them even have a little purple in it is seems? anyway, anything short of tearing entire yard up and starting fresh, how can I get rid of this? I thought of spot treating with roundup or something, but that really wouldnt work as its all over now. It seems like when i fertilize and ironite my lawn, this stuff grows in more instead of my bermuda!!
