Does this kill quack grass? It seems it only yellowed the ones I've treated.
Roundup Weed and Grass Killer Ready to Use Plus is a non-selective herbicide and will kill weeds or grass sprayed directly with this product. Quackgrass generally is a hard to kill weed and may need to make multiple applications to completely control it. The yellowing of the weed is a good sign and for harder to kill weeds, it could take more than two weeks to fully see the results.
