Moss is a ground cover having a thick mat of tiny green leaves and threadlike stems. It is used as ground cover in areas where grass growth is not possible. It helps to slow down soil erosion and prevents moisture loss from the soil surface.
But, moss is technically a weed and can be considered a noxious weed when it attacks your lawn where it is unwanted.
Once it attacks your lawn and is left uncontrolled, it is the sign of big challenges for your lawn in the form of excessive lawn thatch, soil compaction, and ends up in the form of a splotchy lawn.
Moss can be more damaging when it starts to take over the flowerbeds and lawn grass. Actually, it attacks the nutrients and moisture resources of lawn grass and inhibits the growth of other plants. If the controlling measures are not adopted in time, it will start growing towards the structural part of the home and lifting towards the roof.
Moss is much easier to control in its primary attachment and can be removed with help of thatching rakes. But when it takes over the more area of the yard and continuously and speedily spreads towards the roof, walls, and walkways, it’s an alarming situation and that can be controlled with chemical formulas or moss killers for the lawn.
Many dozens of moss killing products are available in the market and it has become impossible to find effective moss killers for the lawn. That’s why I built this guide on best moss killer for lawn reviews, effective controlling methods, and moss killer types.

Why Does Moss Grow in My Lawn?
Grass loves to grow in the sun and shows more active growth in full sunlight while moss loves to thrive in shady places. Moss thieves actively in dumpy and saturated soils.
In the shady grounds, the moisture sustains for more time and becomes the active growth part of moss in the yard.
A yard having more shady places and trees or shade causing plants in the lawn are more prone to get under the attack of moss.
Why Do I Need to Use a Moss Killer instead of a thatch rake?
The most effective moss controlling method is by applying moss killer and then when it dies, remove it raking out.
But one confusing question arises in mind: why don’t we use rakes in the first place to remove the thick layer of moss?
Well, here are some reasons for using moss killer instead of rake;
1. Raking Untreated Moss Can Spread it to Other Areas of Your Lawn
If some parts of your lawn have moss in them while most parts are free of moss attack.
When you will start to rake the moss from those parts, there are pretty sure chances of dropping the alive moss part on the other parts of the lawn and it also comes under attack of moss and it establishes quickly.
This way you will become the reason for more spread instead of controlling.
2. Moss is Easier to Remove When it’s Dead
Moss gets killed by applying the moss killer, it desiccates and turns black.
The dead moss has no connection with the ground which shows that now it’s easier to remove it than if it was alive.

Dilute the liquid moss killer with water and start applying over the moss with the help of a garden sprayer.
In the case of granular moss killer, use a broadcast spreader to gen even spreading over the surface.
After applying moss killer, wait for some time until the moss gets dry and turns brown or black on dying. When the whole moss gets dry, now it’s your turn to rake out the dead moss.
After raking out the dead moss from the lawn, there will be empty spaces in the soil. You will need to apply fertilizers to start up the growth in vacant spaces.

Benefits of Using Moss Killer
Moss in the lawn is much more damaging than growing alone in barren places. It has a drastic effect on the growth of grass and destroys the aesthetic beauty of the lawn.
Moss outcompetes the grass and dominates over the grass in utilizing the nutrients and water resources. Applying the moss killer as a controlling agent for moss is ultimately the best solution to get the grass out of the attack.
There are some prominent benefits of using moss killer as a controlling measure:
- Using moss killer will stop the more spreading of moss over the lawn.
- It kills the moss completely and dries out the alive parts of moss to prevent its again nourishment.
- Iron is the main component of moss killer, which is a responsive agent to dry out the plants completely.
- Applying the combined lawn feed and moss killer product will actually fertilizer the grass after raking the dry moss over the grass.
- Moss killer helps in improving the overall health of the lawn by providing more exposure to sunlight and removing the thick layer of moss from the grass.

When is the Best Time to Apply Moss Killer on Lawns?
The best practice is to follow the directions provided on the product label. But there are some basic things to keep in mind to get the maximum results.
The best time to apply moss killer is late winter or early spring season as during both these seasons the active growth of plants is almost stopped. While spore formation doesn’t stop in moss during winter, so it is good to control it completely to prevent its attack again in the future.
Similarly, some moss killers need to water just after the application to get effective results while some need a dry environment.
Finally, it is necessary to follow the instructions provided by the manufacturer.
Types of Moss Killers
Moss killer comes in two forms: granular and liquid. All manufacturers have different formulations and recommendations and directions to use.
Choosing a unique type of moss killer completely depends on the purpose to use it. Some moss killers are used for walls, roofs collectively while some are specific for lawn and walls.
Here are the two types of moss killers with directions to use and benefits.
Granular Moss Killers
Granular moss killers are commonly used for treating moss in yards or lawns. It has small water-soluble granules and is applied in dry conditions.
They are applied with the help of mechanical spreaders for even distribution and treating large yards in less time.
Such granules are not feasible for treating moss on roofs.
Liquid Moss Killers
Liquid moss killer has a wide range of uses and they are mostly used on roofs and walls. Lawn formulation is also available in the market. But liquid formulations are ideal for use on a roof.
It features liquid formulation containers that are directly attachable to hose pipes. All you need to do is connect the hose end with the container and water automatically mixes the moss. The hose pressure runs and shoots the water jet to easily spray the rooftops while standing on your lawn.
Liquid-based moss killers are the perfect control for moss in flower beds and lawns as it contains iron and other nutrients that provide valuable nutrition to grass and plants.
How to prevent moss growth in your lawn?
- The best strategy to keep your lawn free of moss growth is by maintaining a thick and healthier lawn. The thicker is a lawn, the less room for moss growth.
- Secondly, moss needs compacted ground with poor drainage for growth. So, aerating the lawn with an aerator or gardening fork will open up soil pores and improve the grass growth.
- Never left any dried or fallen leaves on the lawn as they cause stress to grass by trapping the moisture and hindrance to sunlight reach and provides ideal conditions for moss growth. Make sure to increase the sunlight reach on the lawn surface to prevent moss growth.
- Always use a lawn moss killer during the late spring and early winters.
- Grow the grass seeds for shade in shady areas instead of leaving space for moss growth.
