Moss in Grass

Asked April 25, 2019, 7:32 PM EDT

I, and many neighbors, have what looks like moss in my grass. I applied lime last year as I have an acid, sandy soil and shady yard; it is worse this year. I also have a friend in IL with moss. I put a moss killer spray on it a few days ago, but don't see much difference. Help!

Mosses prefer the exact opposite growing conditions of turfgrass. In fact they thrive where turfgrass thins from the favorable conditions for moss. Moist acidic soil in shade is not going to be favorable for grass growth. If you could kill the moss off completely, it would grow back again unless changes were made to the area in question.

Then there are shady lawn alternatives: https://www.canr.msu.edu/news/shady_lawn_alternatives
