The lush green lawnsare obvious everywhere. However, a closer look identifies manyother species besides turfgrass. Crabgrass has invaded many areaseven though a preemergence herbicide was used this spring and thebroadleaf weeds such as white clover, and broadleaf plantain aretoo numerous to even attempt to count.
Renovation means killing all existing vegetation andstarting over.
The extension publication Pm-1055, TurfgrassRenovation has a lot of helpful information for anyone consideringstarting all over with their lawn. For those lawns that are mostly turfgrass, the time to starteliminating those broad-leaves is a few weeks away. Mid Septemberto early November is generally the best time to selectively controlthese weeds with a herbicide. Controlling broadleaf weeds in thefall gives the turfgrass an opportunity to fill in those open areasthat appear after weed control. This results in a denser turfwhich culturally helps prevent weed establishment.
