My lawn has patches of fertilizer burn on it. Can anything be done to revive these patches or is the grass dead and all I can do is go through its pockets for loose change?
From the following link is this advice:
Not so fast.
Deb Brown, horticulturist with the University of Minnesota Extension Service, says the first step in “fixing” such spots is to soak them thoroughly with water. This dilutes the material remaining in the soil, driving it deeper and spreading it harmlessly over a wider area.
“Sometimes that’s all that’s needed, provided the roots haven’t been destroyed,” says Brown. “However, if you don’t see new blades of grass emerging from these spots within a week or so, you can assume the roots are dead. It that case, it will be necessary to replace the grass.”
