Has anyone fought with Quackgrass and won? 2 years in a row of drought conditions the weeds got a strong hold of my yard. I have hit it with weed and feed, that stuff barely made a dent. So I hit the yard with some farm strength 2-4-d. It got most the weeds in retreat pretty good, with the exception of quackgrass and a touch of creeping charlie. All the research I have come up with says only Roundup will kill the stuff. Has anyone found a way to kill this weed without killing the yard?
I am wondering if I very lightly pull a disc over the yard to lightly loosen up the soil and then over-seed with new grass seed. IF I let it grown, not mow for quite a while, is that any chance the tall grass could crowd out the quackgrass or am I asking for additional problems?
