Diagnosing Yellow Spots in St. Augustine Grass

Last summer I noticed yellow spots on my St. Augustine lawn. What could be causing this?

Quick Checks

• Inspect for insect damage (chinch bugs, grubs).
• Fertilize carefully: apply to dry grass, water in immediately.
• Avoid herbicides/insecticides near the lawn unless necessary.
• Water deeply but infrequently (not daily shallow watering).

If spots persist, take a sample to your local extension office for disease diagnosis.
