The answer to 'aeration disease' is that it refers to various fungal diseases that can affect a lawn after aeration. Common causes include overwatering, poor drainage, and compacted soil. Symptoms may include discolored or thinning grass, mushroom growth, and a spongy texture. Solutions include adjusting watering schedules, improving drainage, and applying fungicide if necessary.
In most cases, aeration disease can be addressed with proper lawn care practices. However, if the problem persists or worsens, it's best to call a professional landscaper or turf specialist to diagnose and treat the issue.
