This will be my fourth season of st augustine grass after orginally pulgging my lawn. Last year I experianced a deep green thick lawn.
This year, a mostly faint green color has evolved in an area of the lawn that has a somewhat steep grade down hill to the sidewalk. The contrast between the grass on top and on the declining hill are most apparent.
What could have caused this and how can I return the hill area to it's deep green color?
