Generally, the reason for excessive moss growth in lawns is that the grass is struggling, normally this is due to poor environmental conditions that favour moss for example low light, excessive moisture, or soil compaction. To keep your lawn healthy and growing it’s important to remove moss. Even though your mossy lawn might look green and healthy, the moss will take over if left untreated and slowly crowd out the grass completely.
Moss is easier to get rid of than what you think! Here’s our step-by-step guide on how to get rid of moss in your lawn or watch our video to find out more.
When to remove lawn moss
Spring
Moss can creep in and take over during the winter months and weed growth starts to increase in spring. This makes it the ideal time to apply a granular treatment to get the problem under control, as they compete for the same space as your lawn.
Autumn
During autumn, your lawn is still recovering from the wear and tear of the summer months but its health needs to be maintained to help survive the cold frosts of winter. Autumn moss control and scarification help reduce competition and give the grass more room to grow. It also helps to minimise moss growth over winter, making it less of a problem in spring.
How to control lawn moss
Before removing the moss through scarification it is best to treat the moss with a moss killing lawn treatment. Otherwise, you run the risk of the moss spreading its spores when it is being removed – which could undo a lot of your hard work!
Moss killers are usually based on the chemical Iron Sulphate, which is delivered at a high enough rate to cause a change in the internal chemistry of the moss (killing it). You can see that it has worked as the moss will turn black and eventually brown. Normally the moss can be removed after 14 days. It is essential that before using a registered product like a moss killer you read and follow the product label.
Our range of moss killing lawn treatments are:

How to remove lawn moss?
Westland MossMaster
Westland MossMaster is a child and pet friendly moss remover that naturally nourishes and greens your lawn. It effectively eliminates moss without leaving behind unsightly black patches or stains. The formula contains beneficial bacteria that digest and remove moss, transforming it into valuable feed for your grass.

Kent & Stowe Scarifying Rake
A Scarifying Rake is ideal for encouraging healthy lawn growth by; removing thatch, moss, and dead grass cuttings; opening up the soil surface to improve airflow and the uptake of nutrients and water; preparing the ground for sowing new seeds, and cutting through top soil. Use this tool after mowing the lawn and before putting down lawn seed by using a pull motion to scrape the moss from the lawn.
For larger areas, it is recommended that you use a mechanical scarifier as the work can be quite physically demanding. Any material that is removed can be added to the compost heap (unless otherwise specified by the product label of any treatments applied – such as those containing weedkiller) and it will break down into rich garden compost.
Another option is to prevent moss from being able to establish:
Aftercut Ultra Green Plus
Aftercut Ultra Green Plus is a balanced lawn feed also containing iron that encourages strong, healthy grass growth that helps your lawn to outcompete moss. The product also contains water management technologies that help to create conditions less favourable for moss development whilst favouring grass growth.
How to repair your lawn
It’s important to understand and consider that if you kill the moss in your lawn you could be left with brown and bare-looking patches. You will need to re-seed your lawn with lawn seed to bring it back to life. You must grow new healthy grass over these patches to avoid them being overgrown by moss or new weed seeds.

How to prevent moss from re-appearing
Moss is caused by a combination of moisture in your lawn and weak grass. Moss needs moisture to spread, so you are more likely to suffer from a moss problem in shady areas or in wetter seasons like spring or autumn.
The following steps will help you to prevent moss from appearing in the future:
- To keep your lawn in tip top condition, feed your lawn once a month with Westland SafeLawn for beautiful results
- Thin out over-hanging trees to prevent shade on your lawn
- Re-seed any bare patches using Patch Fix
