How We Prep Your Yard Before New Sod
We learned this the hard way. The very first sod job we ever did, we took a weed eater and scalped the lawn down to the bone. Then we laid sod right on top. Did not till one bit. Not a single piece of that sod survived. Every farmer in the world will tell you the same thing: do not waste your time trying to plant anything without preparing the soil properly.
Our process follows the University of Florida guidelines — they literally wrote the book on this. First, we spray the existing lawn with herbicide. We do this strategically on the hottest part of the day when the sun is blaring down, because the herbicide gets absorbed by the green part of the plant and sucked into the root structure. The hotter and drier it is, the more the plant drinks it in. Then we wait two weeks and spray again. After the second application, we wait two more weeks. That is a full month before we plant anything.
Why a month? Because you need everything completely dead — not just the grass, but the invasive weeds hiding underneath. Torpedo grass, Bermuda runners, nut sedge — if any of those root systems survive, they will grow right through your brand new sod within weeks. Patience during prep saves thousands in replacement sod later.
After the old vegetation is confirmed dead, we till the soil four to six inches deep using a compact utility unit with a cultivator attachment for the large areas and a hand tiller for the tight spots. This breaks up compaction, reintroduces air, and creates loose soil where new roots can establish fast. Sod laid on untilled ground usually does not even grow into the existing soil — the roots stay trapped in the sod piece and never grab hold. Then we level everything to the existing contour, rake along driveways and walks for proper height, and add soil amendments if the pH test calls for it. Only then does the sod go down.
We had a customer with a corner lot who spent a fortune on thirty pallets of sod. We tried to warn them about their sprinkler system — went out of our way to help. They did not have water coverage on that corner and tried to hand water it through a Florida summer. Standing out there with a hose on a corner lot in July is a full-time job, and even then it is not enough. A lot of that sod died. Thousands of dollars gone. The lesson: your irrigation system has to be working before the sod goes down. It is not optional — it is part of the prep.
