It's been a crazy season like no other I can remember. Even the farmers I hang out with are complaining about many of their crops (corn, wheat, beans, - even the hay sucks).
The other thing I try to do is not obsess too much about keeping a perfect lawn. Gut enuf has become my mantra. Lawns are a living, changing thing. Trying to maintain that perfect monoculture is one of those standards that has driven us to over-use of chemicals, just like we need perfect fruit and veggies too. Rant off, LOL.
That Quinclorac is some crazy stuff. Controls grasses AND broadleaves. I've been trying it in rotation to knock out some persistent clover. LOL, my coworker encourages his lawn to have clover!
Clover is fine, its the look alike clover with yellow flowers (Oxals) that is driving me crazy.
People need to focus on soil health as much as they do on eliminating weeds. The grass will do an excellent job of eliminating weeds if the soil health is good.
Clover adds nitrogen to the soil.
