Diagnosing Root Rot in Your Lawn: Quick Tips for Homeowners

by

Maintaining a healthy lawn requires vigilance and regular inspection. One common issue that can severely damage your grass is root rot. Recognizing the signs early can save your lawn from extensive damage and costly repairs.

Understanding Root Rot

Root rot is a disease caused by various fungi that infect the roots of grass and other plants. It thrives in overly moist conditions and poorly drained soils. When roots are affected, they become brown, mushy, and unable to supply nutrients to the grass.

Signs of Root Rot in Your Lawn

  • Discolored patches: Areas of grass turn yellow or brown, often starting at the edges.
  • Wilting grass: Despite adequate watering, the grass appears limp and stressed.
  • Spongy soil: When pressed, the soil feels soft and waterlogged.
  • Fungal growth: White or gray mold may be visible on the soil surface or grass blades.
  • Slow recovery: Areas that are damaged do not bounce back after watering or fertilizing.

Quick Diagnostic Tips

Follow these simple steps to confirm if root rot is affecting your lawn:

  • Inspect the roots: Carefully dig around the affected area. Healthy roots are white and firm, while infected ones are brown or black and mushy.
  • Check soil moisture: Test the soil’s drainage. Excessively soggy soil suggests poor drainage, which promotes root rot.
  • Assess watering habits: Overwatering can create ideal conditions for fungi. Reduce watering and observe changes.
  • Look for fungal growth: Spotting mold or fungi on the soil surface indicates possible infection.

Preventive Measures and Treatment

Preventing root rot involves good lawn care practices:

  • Improve drainage: Aerate the soil and consider adding organic matter to enhance drainage.
  • Adjust watering: Water deeply but infrequently, allowing the soil to dry out between watering sessions.
  • Fungicide application: Use appropriate fungicides if infection is confirmed, following manufacturer instructions.
  • Remove infected grass: Reseed or sod affected areas after treatment to promote healthy growth.
  • Maintain proper mowing: Keep grass at recommended heights to promote root health.

Early detection and proper lawn management are key to controlling root rot. Regular inspections and good cultural practices will help keep your lawn lush and healthy.
