Problem: Grass is matted down
What the lawn is trying to tell you: This, too, could be a fungus problem, according to Chad Diller, marketing coordinator for Tomlinson Bomberger, a lawn care, landscape, and pest-control company in Lancaster, Pa. “Fungus can be caused by consecutive nights of wetness,” Diller says. “If you have an environment of dampness and warm temperatures, this environment can lead to fungi.”
You’ll need to examine the blades of grass close up to see what the problem is. If there are dead spots in the lawn, examine the outer ring of grass adjacent to the dead area to identify the problem. “The key is to look not so much at the dead as at the dying. You might see spots or discoloration or lines across the grass,” Diller says. “With fungus, the morning dew hangs on it, so it’s easier to see. It looks like a spider web.”
University extensions can help you identify the specific fungus, and they offer fact sheets or advice for treating it.
