The optimal aeration timing depends on your grass type. Cool-season grasses benefit most from aeration in early fall or spring when they're actively growing. Warm-season varieties respond better to late spring or early summer aeration. Regardless of grass type, avoid aerating during dormant periods when your lawn can't readily recover from the temporary stress.
The time required varies based on lawn size, terrain complexity, and equipment type. Most homeowners can complete their aeration project within the timeframe of a daily rental. Factors that may extend the process include obstacles in the yard, particularly compacted soil, or challenging terrain features like slopes or uneven surfaces.
Yes, many lawn care experts suggest that aerating and seeding during the same session can be beneficial to your lawn’s growth and overall health. The aeration process creates ideal conditions for seed-to-soil contact, potentially improving germination success. This approach can be particularly effective during the appropriate seasonal windows for your specific grass type.
