Controlling Lawn Moss in Clay Soil: Drainage and pH Solutions

Moss worsening for years in clay lawn. Homeowner asks for help.

Moss = Constant Moisture

• Reduce/stop irrigation.
• Check downspouts – redirect away from lawn.
• Check neighbor runoff.

pH Correction

Add lime to raise pH (moss likes acid). But: must incorporate into soil → destroys existing lawn. Best done during renovation (till, lime, reseed).

Quick Fix

Rake out moss, improve drainage, overseed with shade-tolerant grass (fine fescue).
