Laying Loam/Growing Grass

[ProfessorM]

If the ground is hard you should dump and spread the loam, even a few bags of peat too, and then rototill the whole thing so it is nice and loose down to about 5 inches. That way the roots, when they grow, will penetrate the soil much easier. Pretty hard to grow grass on hard pan soil. Needs to be loose. You can top dress the existing grass with the loam but you cannot smother it or it will die. If I was doing it I would rototill the whole thing. Don't forget the water. My buddy the landscaper will not guarentee a lawn unless the owner hooks up a timer on the water faucet so they don't forget to water. Good luck. Paul
