Q.Torpedo Grass In Centipede Lawn
I purchased a chemical with Sethoxydim as recommended; and sprayed a small portion of my lawn. My question is, how long does it normally take to see results of the torpedo grass receding? Thanks John Gilmore

Make sure to follow all instruction regarding application and reapplication. You may need more than one dose to see results. Consult the instructions on the packaging before use in order to be well informed of the proper use of the product. Doing so not in accordance to the label can be illegal.
Alternatively, you can choose a non-selective herbicide to kill the entire area, and reseed or transplant plugs.
