Q: Why does my centipede grass love the concrete patio and driveway? It’s so green and thick in these areas but not so much in other areas of the yard.

A: Good gardeners notice things like this! I think it’s likely that the soil was disturbed alongside the patio and driveway when they were built, making a good growing area for the grass. In addition, the warmth of the concrete may protect roots from winter cold.
