This is in NTX and my problems were dandelions and thistles, if that helps. Also, in years past I used Bioadvanced 3-1
and it did a pretty good job of killing everything, and I only needed roundup for spots here and there, and weeds poking through concrete.
This year they were more resistant to Bioadvanced, so that’s why I went with WeedBgone, which I got on sale at Home Depot.
