Overwatering

One of the primary culprits behind the formation of dead circles in grass is overwatering. While water is essential for the health of your lawn, excessive irrigation can have detrimental effects. When the soil becomes waterlogged due to overzealous watering or poor drainage, it creates an environment where the roots suffocate and the grass struggles to thrive.

Overwatering can lead to the development of dead circles, often referred to as “fairy rings.” These rings are caused by the proliferation of fungi in the soil, which thrive in excessively moist conditions. As the fungi spread, they deplete the soil of essential nutrients, hindering the grass’s ability to grow and causing circular patches of dead or discolored turf to emerge.

Additionally, overwatering can result in the compaction of the soil, making it harder for oxygen to reach the grassroots. This, in turn, weakens the grass and makes it more susceptible to diseases and pests. The excess moisture also creates an ideal breeding ground for fungal infections, further exacerbating the issue.

To mitigate the effects of overwatering, it’s crucial to establish a balanced watering regimen that aligns with the specific needs of your lawn. This involves taking into account factors such as the grass species, soil type, and prevailing weather conditions. Implementing proper drainage systems, aerating the soil, and adjusting your watering schedule can help prevent the formation of dead circles caused by overwatering.
