Well I bought a sprayer yesterday and some liquid Ortho weed control. I usually put down the Crabgrass fertilizer, but the lawn usually looks like crap after I put it down. So I thought that this year I would try spot spraying the weeds rather than covering the whole yard. Anyone do it this way?? or do you think that I should still put down a few bags of Crabgrass preventer. I would love to avoid putting down Crabgrass preventer if i don't have to, since I really get more flowering type weeds, rather than Crabgrass to begin with.
