Excessive Moss in Lawn — Poor Drainage Indicator

Excessive moss growth in BC lawns indicates persistently moist soil conditions that may be caused by poor drainage or a hidden underground leak.

Possible Causes

  • Poor soil drainage from clay content or compaction
  • Underground water leak keeping soil constantly moist
  • Overwatering from irrigation system
  • Shaded area with inadequate sunlight
  • Low soil pH favoring moss over grass

Recommended Steps

  • 1Test soil drainage by digging a small hole and filling with water — should drain within 24 hours
  • 2Check for underground leak signs if area is wet when it should not be
  • 3Adjust irrigation schedule to water less frequently
  • 4Aerate soil to improve drainage in compacted areas
  • 5If moss persists in specific area despite drainage improvement, call for leak investigation
