I have a really picky customer with a patch of 2 year old sod that is geting thinner and uglier as we speak. The growth is getting lest, the blue grass is dying etc... It was layed on a moderately but overly compact base The rest of the lawn is looking great, but this part has shallow, weak roots and a poor look. The area gets plenty of water. Is there something that I can apply that will help?? Thanks!
