The neat thing about moss… Is think of all the money saved on not having the noisy turf crew in every week… Consider. The savings on watering, and fertilizing… Those violets are edible, and are an important butterfly host plant. Moss lawns are in vogue, people pay good money to get these beautiful assets. Turf is out. California is doing plenty to discourage wasteful turf. You can’t eat it, it is #1non point source of pollution, causes flooding,requires serious amounts of time in maintenance… Is partly responsible for pollinator decline, nothing eats it except grub worms and cinch bugs! Best thing you can do… Is relax, and enjoy the great yard that you have.

Low soil pH, poor air circulation plus compacted soil will also create a favorable environment for moss. Soil test to determine your soil acidity and apply lime as recommended for a fescue lawn. Core aerate to relieve compaction. Rake out the moss before reseeding this fall. An old adage is that moss grows heavies on the North side of the tree. Consider your terrain. If you are sloping north or northeast you will also have a pretty good growing environment for moss. The plus side of that is, you will also have pretty good growing conditions for fescue. I am guessing acidic soil and compaction are your main issue.
