Why does my lawn get Moss in it?

It is common for lawns, especially those suffering as a result of a Winter shade line or north facing to get a Moss invasion visible in the late Winter through to the Spring months.

The moss type that is in your lawn will be mostly Cushion Moss; often referred to as Winter Moss, easily controlled by an application of Lawn Sand which has Sulphate of Iron as a key ingredient.

If you retard the moss activity and then kill it just ahead of raking it out with a wire rake or a mechanical scarifier some 14 days later.  Plan to overseed the bare areas where the Moss once inhabited to fill in these vunerable areas to stop the invasion of Weeds or additional Moss.

A moss invasion is always an indicator of a lawn problem and these causes are listed below.

Causes of Moss Invasion

1. A moist turf – poor drainage encourages the fern-like and tufted mosses
2. A soft, spongy sward with a thick fibre layer
3. A very dry soil, e.g. over drains, on mounds and ridges. Inadequate watering or
   over-drainage encourages the upright type
4. Bare areas remaining after weeds have died
5. Cutting the grass too low
6. Diseased turf
7. Dry acid soil
8. Low fertility, e.g. deficiencies of plant nutrients
9. In appropriate maintenance
10. Inadequate or poor grass cover and growth
11. Low nutrient status
12. Neglect
13. Over-consolidation of the soil - compaction
14. Poor surface levels which may lead to scalping
15. Shade from trees, hedges and buildings and topography – north facing lawn
16. Turf that is not growing under ideal growing conditions
17. Weak and sparse turf
18. Compaction & over consolidation
19. Prolonged periods of wet weather
20. Time of year – autumn, winter and spring
