Robert from Hendersonville, Nc writes

When spot spraying poa annua using Blindside Herbicide WDG, what color does it change to? Will fescue grass grow back in the yellowed area?

I have a lawn comprised of tall fescue that has patches of annual bluegrass (poa annua with seed heads). I want to use Blindside for spot treatment to suppress the poa annua. I live in Hendersonville NC in western NC.

Answer:

Blindside Herbicide will generally turn target weeds yellow before they brown and die. Since fescue grass grows in clumps, you may need to reseed any areas that are bare after you kill undesirable plants in the lawn. Keep in mind that control of poa annua once it has seeded is very difficult.
