DISEASE ID · FUNGAL DISEASE
Dollar spot
A fungus that leaves small, sunken, straw-colored spots in bermudagrass and zoysia lawns. It seldom does much harm to St. Augustine.
How to spot it
- Round, sunken spots of bleached or straw-colored grass, about 1 to 2 inches across
- Spots can run together into bigger, uneven patches
- On a blade, a white to tan spot with a dark brown edge, sometimes hourglass-shaped
- On a dewy morning, cobweb-like threads on the grass
- Mostly on bermudagrass and zoysia
Why it shows up
It's most active on warm, humid days and cool nights that leave heavy dew. Lawns that run short on nitrogen or dry out get hit harder, and so do lawns with thick thatch or compacted soil.
How we treat it
We'll identify it on a visit and recommend the right fix. Often it comes down to feeding: steady nitrogen during the season lets the grass outgrow it. We also look at watering, thatch and compaction. If it keeps coming back, a treatment might make sense, and we'll talk through it with you.
What you can do
- Water early in the morning, not in the evening.
- Knock the dew off with a hose, a pole, or an early mow.
- Don't let the lawn go hungry or bone dry.
