The water from my point well has a lot of iron in it. The grass is Kentucky Blue grass and was originally hydroseeded. My neighbor next door does not have my lawns problem. His lawn/sprinklers were professionally installed in '99 too, by a different company. His grass was from seed and his water is city water; no iron.

-Is the iron a problem?
-Am I stressing the grass with the starter fertilizer?
-Good loam was added over my original lawn- I assume that is deep enough.
-I mow at 2.75" (1" lower for the last mowing)
What do you think the problem is?
