The Ministry of Environment recommends aerating every 1-2 years. Aeration removes thousands of plugs of soil from your lawn. This helps reduce compaction, and thatch build up. It also encourages new root growth, and allows water and nutrients right into the root zone.
As a by-product of the aeration it can also help improve drainage and reduce water logged areas in the lawn. It is highly recommended to seed after an aeration, the seeds will have direct soil contact and protection from the elements increasing germination. It is best to Aerate in the Spring, Early Summer and Fall. Aerations start at just $69.99 + HST! Or bundle an Aeration with an Overseeding and save!
