The spring dethatching service consists of a complete pick-up of surface debris such as excess thatch and dead leaves. This operation promotes a faster recovery of the lawn in the spring and is recommended every year. It is normal to have a thin layer of thatch on the surface of your lawn. However, if the thickness of thatch is too great, it will prevent the flow of water and nutrients to the root system, which will make the lawn vulnerable to the development of diseases and pest infestations.
