The answer to how to care for aeration is to perform core aeration regularly to improve soil health and lawn growth. Core aeration involves using a specialized machine to punch small holes in the soil, which allows air, water, and nutrients to better penetrate the root zone.
For best results, aerate your lawn in the fall when the grass is actively growing. Go over the entire lawn with the aerator, spacing the holes about 4-6 inches apart. After aeration, you can overseed, top-dress with compost, or apply fertilizer to maximize the benefits.
