Core aeration, also known as ground cultivation, will help you build and manage a healthy lawn. If you are not familiar with the term, core aeration means mechanically eradicating small plugs from your lawn to reduce soil compaction to allow room for new growth.
When your soil is compacted, it greatly reduces the circulation of water and air to the roots of your turf. If that happens, you can say goodbye to your healthy and luscious green grass. Just as potted plants can become root bound in a small pot, your grass roots can become overgrown also which will directly effect the health of your lawn if not corrected.
