In the middle of our front yard there is a 3ft x 3ft concrete square that covers a dry well for the basemant sump pump. I can not grow grass on this concrete block. I have tried adding several inches of top soil and seeding. The grass starts off growing fine, but as soon as we get a hot day, the concrete heats up and kills the grass. I also tried a small piece of sod, but same results.

As I mentioned this is in the middle of the front lawn, and ruins what is otherwise a beautiful yard.

Any suggestions?

THANKS
