I picked some Ortho Weed B Gone Max with Crabgrass control to spray mainly thistle, plantain, spurge, and some weed that looks like dandilion but with out the yellow flower in a forclosed property that hasnt been maintained very well. I mixed in a handheld sprayer and walked the whole yard and it didnt even faze it. So i waited a few weeks and still it didnt even tickle it. I mixed it 2.5 oz per gal. Perhaps i could still go stronger??? I know crabgrass control is pointless this time of year but its all home depot had. Maybe i shouldve used WBG Max without it since there may be another chemical in that wouldve worked better. Dunno any thoughts??
