If you notice moss on your lawn, you are right to be concerned. Moss can be a temporary issue, especially after persistent drought or waterlogging, however, it can also point to an underlying issue.
If you have a brand new lawn, for example, a great deal of moss can be indicative of poor site preparation. If you have an established lawn, acidic soil conditions, inadequate food, inadequate aeration, and even bad drainage can result in unwanted moss.
Killing and subsequently removing the moss is only the first step. In order to keep your lawn free from moss, you have to tackle the underlying factors which could be any of those listed above. A good way to do this is to implement an annual lawn care schedule, part of which includes things like correct feeding of the lawn, preparation by scarifying your lawn in spring and autumn, regular mowing, and drainage – which can be improved greatly by aerating your lawn.
There are many types of moss that can grow on your lawn but in most cases, they are coarse and loose, often yellow or green in colour. They form dense tufts that leave the surface uneven. Loose areas of moss can leave your lawn with a spongy feel underfoot. It’s much easier to control moss if you follow a yearly routine than it is to try and remove and kill moss once it’s fully established itself in your lawn.
What causes moss?
Moss can be caused by many things. If, for example, you have sparse grass coverage, the balder areas might be filled with moss. If you have areas of your lawn prone to daily wear and tear, such as areas where people regularly walk or play, this can (unfortunately) create an environment that is perfect for moss to thrive.
Moss often grows in areas underneath trees, or in other shadier spots. Other potential causes include compacted soil, waterlogged soil, drought-stressed grass, or acidic soil. If you mow too closely, fail to maintain your lawn, or fail to give it enough food, it can also result in moss.
Removing Moss
No matter the cause, you need to find a way to control and remove it. As mentioned there are many things that can contribute to the growth of moss across your lawn and the best way to control it is to prevent it. Once you have gotten rid of moss on your lawn you should regularly implement annual lawn care strategies to prevent it from coming back.
Scarification
The first way is through scarification. This is something you can integrate into your annual lawn care schedule. This is best done in September or October, unfortunately, for a short while your lawn will look very bare, however, it will reward you for scarifying and will quickly recover. If you cannot scarify in the autumn then it can also be done in spring.
Vigorously rake the lawn by hand using a rake or use an electric or petrol scarifier. The second two will make the job much easier, quickly removing the moss and other debris that is starting to collect on top of the grass. A scarifier will also remove thatch and weeds from deep into the lawn and will also help water and nutrients get to the roots of the lawn.

Non-chemical ways to control moss and feed the lawn at the same time
You can also apply non-chemical products to control moss but if you do this, mow the lawn short beforehand and leave it for at least 7 days before you mow again. Most of these products need water to activate, so they are better applied as part of your care routine in spring, sometime between March and October. If you apply a product such as Neudorff Organic CleanLawn or Evergreen Norake, rest assured that it will help prevent moss.

Using lawn moss killers
In addition to these, you can use weedkiller controls that are commercial grade and designed to control moss and weeds. Moss killers containing sulphate of iron should be applied to your lawn in the autumn or the spring.
These products will turn the moss black after 2-3 weeks following application, which you should use a rake or scarifier to remove it. When you apply commercial products like these, you can find some that are a combination of fertiliser, moss killer and weedkiller which helps your lawn to improve. Regardless, these products should be applied according to the instructions so that you don’t apply too much. Applying too much can also have a negative effect because this can actually result in dead patches on your lawn. You also need to make sure that you don’t apply lawn moss killers in the wrong weather.
We recommend using a lawn spreader because most are in granular form and this will ensure an even and correct spread as well as preventing the lawn from burning.

Preparing your area for a new lawn to avoid moss growth
If you are planning to lay a new lawn it is vital you make sure you properly prepare the area beforehand. This means making sure you have a good layer of soil underneath the lawn and that the area is free-draining. We recommend avoiding any commercial-grade products for the first 6 months to give the lawn enough time to establish itself.
What can you do with dead moss?
Once you have removed the dead moss from your lawn, you can add it to your compost heap. Moss can be slow to rot and should be mixed in with plenty of other compost material.
