All - New to the forum this is my first yard. Doing a lot of watering because of the new landscaping. But I am getting white grass in the yard. My father was convinced it was mildew, mold or fungus but is baffled. It is almost like white asparagus. It is "Healthy grass", just absent of color, there isn't anything powdery on it. Only thing that has changed is I've added Preen to my landscaping. But the white grass is appearing in the middle of the yard away from the landscaping. And no there is nothing powdery on the blades. I'm happy to take pictures if necessary.
