|Moss in the lawn can be a problem|
If moss is rampant, then treat is as a sign that your lawn is lacking what it needs and is ultimately losing the war. Removing the moss is not enough on its own. It WILL come back.
How to get rid of moss: Step 1 - Understand the cause Pull on your gardening boots, grab a jacket (and a torch if it’s nighttime) and go for a short walk to where the moss is most prolific. Check to see if any of these conditions are true - even one of them could be causing the problem.
- Is the affected area covered by shade? If your grass plant does not receive enough light, it may be weakened and bullied into submission by the more dominant moss
- Is the area in a natural basin of the garden? Most lawns are not flat so water may run and collect in pools. This is not good for grass - but excellent news for moss
- How short is the grass? Mowing your grass too short can weaken it, especially when the plant is under stress
How to get rid of moss: Step 2 - Remove the moss from the lawn Now that you have identified the possible causes of the moss, it’s time to remove it from the lawn. For a smaller area, a simple lawn rake will suffice. For large lawns, use a powered scarifier (either attach it to your lawn tractor or hire a walk-behind unit from your local hire shop). You can afford to be quite rigorous here - just make sure you rake out as much moss as possible. If the moss is severe, consider using a chemical killer. Consult with your garden centre on the best option for you. There are organic alternatives available.

- Spike your lawn. Use a garden fork to spike your lawn - The Gardener’s Journal wrote an article on how to do this. Again, there are tow-behind options for lawn tractors or powered walk-behind units you can hire. This process achieves two things. Firstly, it reduces compaction. The soil becomes looser and air can reach the roots of the grass plant. Secondly, it improves drainage. Water will drain away quicker. This improves growing conditions for your grass and makes life difficult for moss.
- If possible, reduce the amount of shade on the affected area. All gardens are different, but this might mean pruning back a hedge or removing a limb from a tree - use a chainsaw, hedgetrimmer or powered pruner as appropriate. In some cases, it’s as simple as moving a child’s trampoline or climbing frame.
- Feed the lawn. When did you last treat your lawn to a good meal? Regular feeding in spring or in the early part of summer will give the grass the nutrients it needs to grow. Talk to your local garden centre about suitable weed and feed products
- Change your mowing habits. Cutting too short can cause stress to the grass plant, especially if the weather is extremely wet or dry. Have the blades on your lawnmower set too low and you could be in danger of scalping the grass. This will leave bald patches that can be infiltrated by moss. Little and often is the trick. Look at the height setting on your lawnmower. If it’s set too low, raise it up by a couple of settings.
- If you mulch mow, consider collecting the grass clippings instead. A poorly performing mulching cutter deck may leave long clippings on the lawn. This can contribute to a mat of grass material, called thatch forming above the roots. Thatch can prevent light and water from reaching the roots of the grass.
- Consider applying a top dressing to the lawn. This will help stimulate new grass shoots and, over time, will begin to level out the lawn and remove any dips.
