Soft, Squishy Lawn
My lawn is five years old and is soft year round, especially after rain. We live in a suburb of Oklahoma City. How can I firm it up?

It sounds like you have some drainage issues, which may be causing the lawn to become soft. You can regrade the yard some by adding thin layers of topsoil over the grass in the trouble areas and around the house, sloping slightly so that water/rain runs away. You will probably have to do it a few times, but just add a thin layer of topsoil, not enough to completely cover the grass but enough to bury the grass about half way up the blade. Once the grass has re-established at the higher level, do it again until the drainage issues are gone.
