Now that my centipede grass has gone dormant and turned to brown, I get a better idea of my weed issues. I was going to spray the affected area with Ortho Weed Be Gone. Does anyone agree or have a better solution? Ironically a much larger area of centipede lawn adjoining the section shown in the photo does not have this problem.

They are to go in a area that has a 5 to 10 degree slope, shold I level the planters or can they go with the slope?
