The answer to 'grass dead trees' is that there can be several common causes for dead grass and trees in a landscaping situation. Drought, pests, disease, and improper care are some of the main culprits. Symptoms may include discolored, wilting, or patchy grass, and trees with dying or dropping leaves.
For dead or dying grass, the solution may be as simple as adjusting your watering schedule, aerating the soil, or treating for pests or disease. But if the problem persists, it's best to call in a professional landscaper to diagnose and treat the issue. For trees, a certified arborist should be consulted to determine the cause and proper treatment, which could involve pruning, pest control, or even tree removal in severe cases.
