Lawn aeration may be the most over looked service, however it has the biggest impact on the overall health of your lawn. Aeration provides a number of proven benefits. First, it breaks up soil compaction, allowing oxygen and water to get down to the root zone so grass can grow thicker and healthier. Secondly, it provides excellent conditions for over seeding, which allows new grass to establish itself and fill in thin areas. Annual aeration maintains a healthy lawn and is most effective when done in the fall.
