…tell the "Powers that be" that they're best at Backgammon…I'd check the irrigation coverage on said mounds; likely too much in that it's too thick…or not enough, in that it just ain't growing…remember though, most of those "chocolate drops" are buried stone piles, meaning the irrigation ain't gonna hold…what you may have is a raised gravel pile….
And remember that it's a mound, that water will tend to run away from it…if it's a problem of getting turf established, it just may need a little hose detail to get it started…
