I recently discovered the weed that was taking over my centipede lawn is nutsedge so I purchased some Sedgehammer+. In regards to application, I know that I'm supposed to apply it once, then wait a few weeks for the 2nd application. My question is once it turns yellow and dies, will my centipede overtake that area again? Also, should I just let it die off or should I try to pull it up once its dead? I have a feeling it will leave some bare patches so I want to make sure I take care of it the best way possible. Let me know what you guys think I can do and what worked best for you in regards to using the product. Thanks
