Lime Does Not Control Moss
Q: I have some mossy areas in my lawn that could use some lime. How much?
A: It is a myth that lime eliminates moss from a lawn. My backyard patio has several large patches of moss growing happily in the cement grout between adjacent stones. That is certainly a high pH environment but the moss grows vigorously there anyway. Manage the moss by removing the things it likes: shade, excess moisture and hard clay.
