The answer to 'why is my aeration' is that there could be several common causes, including soil compaction, thatch buildup, and poor lawn drainage. Symptoms may include thinning grass, poor water absorption, and reduced nutrient uptake. The main solution is to perform core aeration, which involves punching small holes in the soil to allow air, water, and nutrients to penetrate the roots more effectively.
Aeration is an important maintenance task for healthy lawns, but it's usually best handled by a professional landscaping service. They have the right equipment and expertise to ensure the job is done properly. DIY aeration with a manual core aerator can be effective, but it's more labor-intensive and may not reach the same depth as power equipment.
