I’ve recently noticed that my lawn, which was once a lush and vibrant green, is now showing troubling signs of distress. Could you help me understand the potential causes behind this alarming transformation? Is it the result of insufficient irrigation, or perhaps an issue related to the soil quality? Might pests be feasting on the grass, or could a particular fungal infection be to blame? Furthermore, what are the telltale signs I should be on the lookout for in order to identify the specific problems affecting my lawn? Should I consider altering my fertilization routine, or is it more prudent to focus on aeration and overseeding? Additionally, how do seasonal changes impact the health of grass, and are there preventive measures I can take to avert such crises in the future? Any advice on how to rejuvenate my beleaguered lawn would be greatly appreciated.
