What causes rust-colored grass?

Answer by  Joel (82)

The most likely cause for grass turning a rusty brown color is dehydration or lack of sun. Either hook up a sprinkler or cut away the surrounding foilage.

i think that you have a lot of iron in your water so the grass is sucking that water up and it is changing the color of the grass you should check for a iron deposit around your house. check your water for a lot of iron to just make sure
