The answer to 'how to care for aeration' is to regularly aerate your lawn to improve soil health and promote grass growth. Aeration involves punching small holes in the soil to allow air, water, and nutrients to reach the roots of your grass.
The recommended frequency for aeration is once per year, typically in the fall when the grass is actively growing. You can rent a core aerator machine or hire a professional landscaper to do this for you. Be sure to water your lawn thoroughly before and after aeration to help the soil and grass recover.
