You are likely to notice moss in your lawn from October to March. This is because the weather cools and dampens, favouring growing conditions for moss. Moss is normally treated during November, December, January and February when it is most active. Moss loves wet and boggy conditions so naturally wet lawns or a lawn with high thatch levels trapping water are ideal.
Mosses are simple flowerless plants that form in clumps. Water and nutrients are absorbed through their leaves. They reproduce by spreading spores and have no real systems of transporting nutrients and water like other plants do. Moss is often a secondary problem in a lawn, the primary being wet conditions at the soil surface. High thatch levels often go hand in hand with moss infestation as do areas with high water tables or poor drainage. Sandy soils seem to be less affected due to their good drainage.
How do I get rid of moss in my lawn?
Improving drainage by aerating. Scarify to remove thatch. Scarifying will also help reduce the moss. A solution of ferrous sulphate, or Iron, will help to control moss but there is no moss “killer”. The ferrous sulphate acts on contact. If the moss is particularly thick the moss will survive beneath and grow through, usually between 8-12 weeks after application. At this point another application can be made but at LawnsOne we would recommend mechanical removal to aid the process first.
Ferrous sulphate can be applied prior to scarification and aeration or post works. It is the opinion of LawnsOne, if the moss is being controlled either is fine and often the decision is more about the logistics of completing the process. The LawnsOne Repair and Rejuvenate process of scarification, aeration and seeding will help to physically remove thatch and moss, improve drainage at the soil surface and help outcompete the moss. This is very thorough, tried and trusted way of achieving fantastic results for your lawn in the quickest time.
A less expensive alternative to reducing thatch and moss is to use a thatch busting fertiliser, high in potassium, which breaks down the moss and then bacteria, carried in the fertiliser, reduce thatch by ingestion. This process can be effective but is more reliant on moisture and temperature levels than the LawnsOne Repair and Rejuvenate process.
Key Points to Remember
- Moss is usually a secondary problem. Fix the primary problem first
- Ferrous sulphate is a control method not an outright killer
- Use the LawnsOne R & R or the thatch buster to reduce moss and thatch levels in the lawn
