topdressing mixture for lawns
what are the benefits of topdressing a lawn? what formula/mix is recommended???
i have several ruts/bumpy areas in my lawn and thought using a topdressing would help level things out a bit while giving the lawn a boost. i've heard that sand is part of a recommended mixture but i should NOT use it because of my irrigation system. sand would not be good for sprinkler heads.
p.s. my soil seems to be clay-like.
