What invites moss?

ways to kill moss

Before we jump start incorporating remedies to get rid of moss, we need to know that it is the environment that promotes the growth of moss. There are following conditions that may invite moss so better be aware of them.

Moist or wet soil: If the soil of your lawn remains consistently moist or wet, the moss may occur since moist soil is an extremely favorable condition. You need to check for the drainage system. Sometimes, water remains on the surface of the ground due to poor drainage.


Improve the drainage system so that water-logging may stop. It will discourage the growth of moss on your lawn. Also, we recommend the irrigation of the lawn only when it is needed. An over-irrigated lawn may end up with excess moisture resulting in moss invasion.

Soil Condition: We recommend performing a soil test to find out the condition of the soil. You can purchase a soil test kit from a retail nursery center in your area, or you can call a local laboratory that provides this service.

The acidic soil condition is ideal for the growth of moss, and if the test results reveal the pH level below 5.5, which is too low, the soil is more acidic.


We suggest applying lime according to the soil test results to promote the growth of turf so that it can out-compete moss.

Shade: A little shade is normal, but the areas covered by medium and dense shades are susceptible to the invasion of moss.


To help overcome this situation, you can’t rotate your home toward the sun (pun intended), but you can allow sunlight by pruning the trees and by thinning down their canopy.

Pruning the trees is not only good for the health of your trees but also the grass, as it will allow more sunlight to pass through and cast on the grass. It will reduce the moisture of the soil and will promote the growth of the grass that will eventually alleviate the growth of moss.

Compaction of the soil: The grass doesn’t grow well on the compacted parts of the soil, which is a favourite spot for the moss. The soil compaction also doesn’t allow proper drainage resulting in moist soil allowing moss invasion.


An unattended lawn may have a moss invasion. Therefore, you need to provide proper care to your yard to keep it safe from weeds like moss and to maintain its aesthetic beauty.
