Aerating your lawn is essential for promoting healthy root growth and improving soil compaction. The best time to aerate your lawn is during the growing season when the soil is moist but not waterlogged. Early fall or spring is typically the ideal time for aerating, as these seasons provide optimal conditions for grass to recover and establish strong roots. By aerating your lawn at the right time, you can ensure maximum effectiveness and long-term benefits for your lawn's health and vitality.
