In the dead of winter in the low elevation deserts, even the overseeded lawns are growing slowly. Staunch turf advocates who want a lawn or commercial sites requiring one, have a easy option for establishing a lawn in the dead of winter.
Overseeded sod is precisely what the name implies.
It's bermudagrass sod that has been overseeded with perennial ryegrass already at the sod farm. The same procedures are used to prepare the soil for installing overseeded sod as you would do for any other sod. Make sure the overseeded sod looks even at the surface. You may need to sprinkle some seed on the top of any damaged pieces. Before laying the sod, irrigate the soil 2-3 days before the installation.
