How to rid your lawn of moss
Moss becomes most prevalent in winter when there is additional moisture and a lack of warmth to dry out surfaces.
What is Moss?
Mosses are small green non-vascular plants that grow in clumps. They are generally only a few centimetres tall with extremely thin leaves.
Moss enjoys wet, shaded and compacted conditions. It is important to understand that moss itself isn’t the problem, it is the favourable conditions the moss enjoys growing in. Turf on the other hand, generally hates these conditions, so you need to act quickly before the moss spreads.
How to remove Moss
If you are already plagued with moss, you will need to remove it to enable your lawn to repair and spread back into the affected area.
- You can do this by physically removing it with a spade or rake. Be sure to get underneath it and remove the roots from the ground as you do.
- Moss killer usually contains iron sulphate. Iron can be good for your lawn when it is deficient. But moss doesn’t like it too much, so an application of iron sulphate will usually cause the moss to die off.
- Mixing water and dishwashing liquid and spraying the moss with it, is also another method often used to kill moss.
How to ensure moss stays away
The key is to focus on the cause of the problem, so the moss doesn’t keep growing back.
Aeration – Aerating compacted ground will help the area drain better and allow oxygen and nutrients to the roots of your lawn allowing it to fight back against the moss.
Improve drainage – If there are substantial drainage issues, you may need to look at putting in a drain or ag-pipe to drain the water away and stop it from pooling.
Reduce shade – By reducing the amount of shade where possible, you will help the sun dry the area out much quicker. This will ensure it doesn’t stay wet for long enough to be favourable for moss to grow.
Check your soil pH – Make sure the area has a pH level optimum for your grass to grow. You may find an application of Lime is required if the soil is too acidic. Moss prefers acidic soils, but it will also grow fine in alkaline soils. Grass prefers a pH of 6.2 to 7.0.
After removing the moss and addressing the causes of the problem, it is a good time to fertilise your lawn to encourage your grass to repair.
