The benefits of a proper core aeration service are tremendous. Overtime, every lawn will be compacted due to foot and lawn mower traffic, and also water practices. When the soil is compacted, it becomes more difficult for your lawn to absorb water and nutrients to their fullest capability. As result, the root zone of grass blades will be unable to grow and root deeper into the soil where there is more and better nutrients and water. Eventually grass disease can occur and balding or patch grass will appear.
