The answer to 'hedge thin grass' is that there are several common causes, including lack of proper maintenance, soil compaction, and pest or disease issues. Symptoms can include bare or thinning patches in the grass, stunted growth, and an overall unhealthy appearance. Solutions may involve aerating the soil, overseeding, applying fertilizer, or treating any underlying problems.
In many cases, homeowners can address thin grass around hedges through DIY methods like dethatching, overseeding, and adjusting mowing and watering practices. However, if the issue persists or is caused by more complex problems like soil pH imbalances or pest infestations, it's best to consult a professional landscaper who can properly diagnose and treat the problem.
