In general terms, moss will form where there is a persistently damp area on the lawn. This can be found on poorly drained lawns, where there are bare patches (potentially due to mowing too low) of firm ground where water is retained or where there is a build-up of thatch.
Thatch – which is debris in the lawn formed by items such as dead grass stems, weak grass, lateral growing grass, etc – is a common problem. The thatch retains water, forming a moist area of ground ideal for moss infestations. If shaded from the sun, these patches can remain damp year round, forming unsightly and damaging heavy moss areas on your lawn. Although using a moss killer is popular, the key is to first target the cause or the moss will keep returning. Bare patches should be seeded as soon as possible. To remove the thatch build-up, the lawn should be raked by hand or by using a machine called a scarifier.
To improve drainage, the ground should be spiked with a fork or by using a machine called an aerator. Once completed, any moss left will gradually die as the temperatures increase. Most importantly, when these activities are completed the lawn should be regularly mown at about 1 inch high to help develop a thick, lush lawn.
LawnTender provide a full moss control service, continually assessing your lawn for signs of moss and the causes for its development. We used the very best scarifiers, aerators and treatments to both address this problem and ensure the reasons for it do not have an opportunity to develop and allow its return.
