Why Should I Aerate the Grass?
First and foremost, a healthier root system means healthier grass. It may not seem that your lawn is compacted, but it happens easier than you may think. Vehicles or small equipment driven on your grass are obvious culprits, but even outdoor entertaining or yard play by kids and pets can leave your lawn compacted. If your grass often looks stressed, your soil is hard to the touch or rainwater puddles up where it used to be absorbed, you may have compaction problems. Confirm your suspicions with a simple screwdriver test. Take a regular screwdriver and stick it into your lawn’s soil. It should slide in fairly easily. If you meet resistance, your soil is compacted, and core aeration can help.
