A couple weeks you guys confirmed that I had crabgrass. I've been following your advice to combat it, but either I'm losing the battle, or I have more than just crabgrass - a lot more has popped up in my lawn despite spraying Weed-b-gon (yes, with quinclorac) quite liberally. So today I just pulled weeds by hand since the spray didn't seem to do much. I realized some of what I thought was crabgrass is pretty tall and slender. Is this just young crabgrass, or something else?
The picture also reveals another question I have - brown grass. I have a lot of it mixed in with seemingly healthy green grass, It isn't spotty, it's just mixed. What could cause this? I'm fairly certain my lawn is getting enough water. My pH in May was 5.77, and I applied the recommended amount of lime since then. I fertilize (I had been following Scotts program but switched to Milorganite). I don't know what else it could be.
