My lawn is in dire need of aerification. I know mechanical aeration leaves the lawn messy for a few days, so while skimming websites online I happened to find this little product. It's a liquid aerifier that simply goes on the lawn by spraying it with a hose unit. Has anyone ever used this product before? Results?
