Soil compaction and aeration
Another common cause of gaps is a lack of aeration. Densely compacted soil makes it difficult for grass to grow and establish new roots. Compacted soil is likely to occur in areas of the garden with increased footfall, such as footpaths or play areas. When soil is compacted, air, water and other nutrients are prevented from reaching down to the roots, stunting healthy grass growth.
Aeration is one of the most useful lawn maintenance techniques, and can easily provide more benefit to your grass than most other lawn maintenance techniques. To aerate your lawn, repeatedly plunge a garden fork about 2 inches into the ground creating small holes. Do this regularly around the lawn until the whole area has been aerated. This is a good method for preventing moss growing as the grass can recover and stifle the moss spores.
How to remove moss from the lawn
If you have a small garden, then you can rake the moss up using a handheld rake, like those available from GARDENA. However, can be quite physical work, and may not be suitable for some gardeners.
Many gardeners use as moss killer or herbicides based on either glyphosate or iron sulphate. The result of any of these chemicals is much the same. The moss will wilt and die, making it much easier to rake up. However, do be aware that other plants may be affected by the herbicides you choose.
Using moss killers and chemicals will only offer a short-term solution in removing moss, and will not offer any long-term benefit to your lawn.
If you use chemicals to remove moss patches, you will need to rake it up and collect it. The dead moss will not break down or add nutrients back into the soil. Instead, it will sit on the top of the lawn and eventually become thatch, which can be more damaging to your lawn.
