4. Use enough topsoil
A common mistake seen by Sopko is a lawn that’s newly installed but without adequate topsoil. “People are frustrated to pay so much for topsoil but it has good payoff,” he says. Per USDA recommendations, topsoil ought to have 40 percent organic content, which helps trap moisture in the soil. Otherwise, the water will run right through and you will be caught in a vicious cycle of constant watering and irrigating to keep the lawn alive.
