4 Steps To Remove Moss From Your Lawn

Tuesday 23rd April 2019

A build up of moss in your lawn can be a real pain in the grass… 

That’s why we’ve put together these top tips for how to rid your lawn of moss. 

A little background info:

If left untreated moss can take over your whole garden, so it’s important to keep it in check as best you can. If moss is growing in your lawn then it is likely down to one or a number of reasons; 

1) low soil PH
2) lack of necessary nutrients
3) poor drainage
4) excessive shade. 

It’s important to note that it’s one thing to rid your lawn of moss temporarily, but another to keep it away permanently. For best results use the guide below to rid your lawn of moss in the short term but also be sure to address the reasons that it is growing in the first place. 

The best time to remove moss is in the Spring time so make sure to follow the steps below during this time of the year.

The first step is removing as much excess moss from your lawn as possible using a rake or scarifier. For smaller lawns a standard rake should do the job, although for larger lawns you will likely need to use some larger equipment like this scarifier which can be rented from Kellys Point Hire for £45 / day ex VAT. 

Before raking or scarifying make sure to mow the lawn fairly close to better expose the moss and reduce resistance on the rake. 

Do not expect all of the moss to be removed during this first rake as there will likely be quite a bit still left once finished.

After the first rake is done, apply a moss killer evenly to your lawn. A product like Aftercut All In One is ideal as not only will these kill mosses and weeds but will also stimulate grass growth. 

Apply at a maximum individual application of 35g/sq.m. Ensure to apply the granules evenly to ensure complete and even lawn coverage. To do this we recommend using either a handheld spreader like this one or a push behind spreader like this one.

Aftercut should be applied when the soil is moist but the grass itself is dry e.g. the ideal time to spread would be a dry, sunny, non-windy day the day after it has rained.

After applying your Aftercut make sure to water the lawn within 48 hours if it does not rain.

Do not mow the lawn for another 3 to 4 days after applying the moss killer.

Between 7 and 14 days after applying the moss killer cut the grass again, fairly close, to expose the moss and rake. 

Again use a rake for a smaller garden or a scarifier for a larger garden. The 7 to 14 days will have given the moss killer time to work, loosening the moss, and this time around when your rake the lawn most of the dead moss should lift.

The removal of the moss may have left empty patches in your lawn, especially in cases where there was lots of moss to begin with. Should this be the case then use lawn seed to fill in the gaps quickly before weeds have time to grow. 

We recommend a product like Grow-Sure Multi Purpose Lawn Seed to do this.

Mow the grass fairly close before applying the lawn seed. If the ground is compacted then make sure to aerate it first. For smaller gardens this can be done by sticking a garden fork deep into the ground approximately every 1’. For larger gardens use a mechanical aerator like this one which can be hired from Kellys Point Hire from £50 / day ex VAT.

Spread the lawn seed evenly across the garden using your handheld or push behind spreader. The seed should be spread at approximately 25g/sq.m. in 2 passes over the garden - once up and down and once left to right i.e. the 2 passes should be at right angles to each other. 

Once the seed has been spread, lightly firm the ground by walking over it or using a roller like this one which can be hired from Kellys Point Hire for £10 per day ex VAT.

Once this has been done, lightly rake the grass to ensure that the seed has been absorbed into the surface. 

If the weather forecast is for rain then no watering is required, however if it is not due to rain then make sure to water the lawn thoroughly, every day, until the grass begins to grow, using a fine-rose watering can or sprinkler, taking care not to wash the seeds away. 

Mow for the first time when the grass is 5-8cm high, gradually lowering the cutting height each time you mow the lawn until the mowing height is down to approximately 2.5cm. 

At this stage you should be left with a nice, grassy lawn with very little moss.

It is important at this stage to maintain your new, healthy lawn, so make sure to educate yourself on how to feed, fertilise and generally maintain your garden throughout the year so that all your moss-ridding hard work hasn’t gone to waste!
