Moss in Lawn: Fix Drainage, Not Just Kill the Moss

Moss thrives in wet, shady, compacted, acidic, low-fertility soil. Killing it (e.g., Gardens Alive ‘Moss Aside’) is temporary—fix the moisture and drainage to prevent return.

Root Causes

• Poor drainage → constant moisture (moss has no roots, needs surface water).
• Shade, compaction, low fertility, acid soil.

Real Solutions

• Improve drainage (aerate, grade, French drains).
• Add organic matter to improve soil structure.
• Soil test to guide pH and fertility.
• Lime acts too slowly and minimally to help.

Product Option

‘Moss Aside’ (fatty acids) kills moss fast but doesn’t solve why it’s there.
