The answer to 'aeration bare spots' is that bare spots in your lawn are often caused by soil compaction, lack of nutrients, or damage from pets, pests, or foot traffic. Aerating the soil can help address these issues and promote healthy grass growth.
Aerating involves punching small holes in the soil to allow air, water, and nutrients to better reach the grass roots. This can be done with a manual core aerator or a powered aerator machine. Aeration is best done in the fall when grass is actively growing. After aerating, you may want to overseed the bare spots to help the grass fill in.
