The soil beneath your lawn can become hard and compacted over a period of time. This could be due to heavy vehicle traffic, drought, lack of correct maintenance over a number of years, regular walking or even dogs running up and down the same patch of lawn. Compacted, hard soil results in a reduced lawn health and here’s why…
Lawns, and therefore soil requires oxygen for their very survival. In a compacted lawn there is less oxygen than is needed for good health. Hard soils also have issues with absorbing, distributing and retaining water. Without appropriate levels of both water and oxygen your lawn will continue to struggle and may eventually succumb and die. Hard, compacted soils require aeration of the soil. Aeration or lawn coring is often enough to repair most lawn compaction issues. The process of aeration is fairly simple; plugs of soil and turf are removed from the entire area of your lawn. This breaks up the hardness of the soil below the lawn and allows nutrients, water and oxygen to get quickly and easily to the root system of the lawn.
In the case of a severe issue of hard lawn soil, an extreme solution is required. Use a rotary hoe to plough through the entire top of the soil down to a depth of 10-20cms. This process will destroy the lawn but in some extreme cases this is the only option available to alleviate long term issues with hard soil. After the process of hoeing the waste material is removed, the area levelled, products such as gypsum or coarse sand added to stop the problem recurring. Then you will be able to install a brand new lawn and know that it and the soil beneath will be easily able to absorb the oxygen, nutrients and water it needs to be healthy.
