Moss control and treatment
Many lawns contain an element of moss – this can be a temporary problem following drought or water logging; or lawn moss may be more persistent, suggesting a problem with underlying conditions.
There are many reasons why moss might infiltrate both new and established lawns and these often relate to poor vigour of the grass, caused by:
- Soil pH problems
- Poor nutrition
- Insufficient aeration
- Poor drainage
- Shade
- Wrong mowing height


Moss Treatment Types
Generally speaking, when there are significant levels of moss, we will need to remove them physically by scarifying. This is a process where we use a mechanical rake to comb the moss out of the grass. We will then bag it up and will remove it from your property, so you do not have to worry about it.
Here we are scarifying a significant amount of moss, out of a lawn on North Hertfordshire. It does look to be a very robust process but once the moss is removed, the lawn will recover very quickly and will be in much better condition.
If conditions and time allow, we will dehydrate the moss first using either carfentrazone of iron sulphate which means it is easier to remove and causes less physical stress to the grass plants.
After we have scarified, we can overseed if the conditions are right which is a good opportunity to get fresh “genetic” into the lawn in the form of bright, green new varieties of amenity grass.
We will then suggest a programme as to how you can help with the management of the lawn so that the problem is much less likely to occur.
