St. Augustine Too High? Gray Leaf Spot & New Sod Thickness

Raleigh St. Augustine at max mower height. Fighting gray leaf spot weeks. 1) Height worsens disease? 2) Gray leaf spot cure? 3) New back yard sod not thick as front—when?

Height + Humidity = Disease

Tall grass traps moisture. Rain PM + dew + morning irrigation = wet all night. Lower height improves airflow.

Gray Leaf Spot Management

• Lower mow height.
• Cut irrigation, stop fertilizing.
• Fungicide now (azoxystrobin, pyraclostrobin). Organic later.

New Sod Thickness Timeline

Must root, then stolons run. 8 weeks minimum. Water daily AM. No fert until rooted. Patience.

Lower the canopy, dry the leaves, treat the fungus.
