I live in North Carolina where we have a great deal of red clay in the soil. I work with an individual who claims you cannot over-lime a lawn, in fact the more lime, the better. He also claims that adding gross amounts of lime eliminates mushrooms and moss. I thought the accepted reason for adding lime was to balance the PH in the soil by adding suggested amounts of lime on the bags by the manufacturer. My question is can you add too much lime? What's the bottom line?
