The answer to 'why is my sod dead trees' is that there are several common causes for sod dying, including improper installation, drought, pests, and disease. Sod requires proper preparation of the soil, adequate watering, and ongoing maintenance to thrive.
One of the most common issues is drought stress. Newly installed sod needs frequent watering, especially during hot, dry weather, to establish a deep, healthy root system. Failing to water the sod consistently can lead to it drying out and dying. Pests like grubs, chinch bugs, or sod webworms can also damage the roots and cause the sod to deteriorate. Diseases like fungal infections or dog urine spots can also kill off patches of sod.
