The answer to 'aeration schedule' is that most lawns should be aerated once or twice per year, typically in the spring and fall. Aeration involves using a machine to punch small holes in the soil, which helps improve water and nutrient absorption, reduce soil compaction, and promote healthy grass growth.
The best time to aerate your lawn is when the grass is actively growing, such as in the spring or fall. This allows the grass to quickly recover and fill in the aeration holes. Aerating in the summer when the grass is dormant can actually damage the lawn. The frequency of aeration may also depend on factors like soil type, foot traffic, and thatch buildup in your lawn.
