My centipede grass is not turning green in all the areas. This is my second season of having centipede grass. Last year it was very thick and I always cut it about 2in and never bagged the clippings. I'm noticing in some areas that where the rain water and water from the irrigation system that doesn't drain right away that the grass is completely dead under the thatch. Its pretty much like that the for the whole yard. Under the heavy thatch its nothing there but dead grass.

Do you guys think I should rent a dethatcher and detach the lawn, then aerate the lawn and over seed it with centipede seeds? Or just dethatch the lawn.
Any suggestions would help.
thanks
