The answer to 'why is my shrub dead trees' is that there are several common causes for shrubs or trees dying, including disease, pests, environmental stress, and improper care. Some common symptoms include wilting, discolored leaves, and dieback of branches. To diagnose and solve the issue, it's important to carefully inspect the plant, identify the underlying cause, and take appropriate action.
If the problem is due to disease, pests, or environmental factors like drought or frost damage, homeowners may be able to treat the issue themselves with proper pruning, pest control, or adjusting watering and sunlight exposure. However, for more complex problems or advanced disease, it's best to consult a professional landscaper or arborist who can provide expert diagnosis and treatment recommendations.
