You, among many other homeowners, could be wondering, why does my lawn have moss? There are many reasons why moss is thriving on your lawn. To find out, keep reading!
Why does my lawn have moss? Your lawn has moss because it has thin and weak grass. The soil in your lawn lacks enough nutrients, imbalanced soil PH, or you have excessive shade.
There are various ways of getting rid of moss from your lawn.
“There’s a misconception that once the moss is killed, it won’t come back. But it will if you don’t change the environment.” Kowalewski., A, turf grass expert, OSU.
Raking out the moss may be a temporary solution to the problem. You have to deal with the underlying conditions that led to its growth. Otherwise, moss will keep growing in your lawn.
Poor Drainage: Perfect Environment for Moss
Is your lawn well-drained, or are there sections of your lawn saturated with water? Poor drainage could be a result of using clay soil or compacted soil that retains moisture.
Water gets trapped in the soil, creating a perfect environment for moss to thrive. Grass grows in well-drained soil, not soggy soil.
Excessive Shading Allows Moss to Prosper
Having trees in your lawn adds aesthetic beauty to your lawn. But too much shading prevents sunlight from reaching the grass.
Excessive shading will contribute to moist soil leading to unhealthy grass growth. There will be patches without grass, and soon, moss will start growing in the spaces.
Mosses spores live in the air. They will germinate in your lawn once it’s conducive for their growth.
Poor Mowing Can Weaken Grass, Allowing Moss to Take Over
Wondering why moss is growing after trimming your lawn? Very short mowing minimizes the chances of your grass thriving.
When the grass is too short, photosynthesis gets inhibited. Your grass starts to weaken, leaving spaces for moss to survive.
Very Acidic Or Alkaline Soil Kills Grass, Leaving Gaps for Moss
Grass does not grow in soils with very high or very low PH. Moss grows in almost all types of soil conditions.
When the soil PH in your lawn is too low or too high, nutrients lock up. The grass weakens, leaving spaces. With time, moss occupies the spaces left.
You may wonder, how do I get rid of moss in my lawn? Taking care of your lawn is not rocket science. For answers, read on!
