Preventing/Dealing with Algae and Moss in Residential Lawns
Moss and algae are primitive plants. They don't kill lawns directly, rather, they take advantage of ideal growth conditions and then take over an area. This might be related to our cultural lawn practices such cutting the grass quite short and/or low nitrogen fertilization. Other factors include too much shade, soil compaction, wet conditions due to poor drainage, poor air circulation and improper pH levels.
