After aerating my lawn, what steps should I take to ensure its optimal recovery and growth? Is there a systematic approach to follow post-aeration that maximizes the benefits of this vital process? For instance, how important is it to apply a suitable fertilizer immediately after aeration, and are there specific types recommended for this purpose? Additionally, should I consider overseeding during this time to bolster the grassy areas that may be thin or unhealthy? What role does watering play immediately subsequent to aeration, and how frequently should I irrigate my lawn to promote effective soil absorption? Furthermore, how do weather conditions influence the post-aeration care regimen? Should I avoid heavy foot traffic on the lawn for a specific duration, and if so, what is the rationale behind this precaution? Ultimately, what are the critical mistakes to avoid in the days and weeks following aeration that could hinder my lawn’s recovery?
