I have some crabgrass and some yellow nutsedge that I'd like to eliminate. 20k of tifway 419 that I'd like to live another day. The weeds are prevalent enough that I'm thinking blanket app, I could spot treat but it's easy enough for me to blanket. It's hot here now, highs in the 90s plus every day. What's everyone's favorite weapon? All I have in my inventory at the moment is MSM, and the crabgrass just laughs at that.
