The answer to 'shrub dying' is that there are several common causes, including improper watering, pests or diseases, and environmental stress. Symptoms may include wilting, discolored leaves, and branch dieback. Solutions depend on the underlying cause, but can include adjusting watering, treating pests or diseases, or relocating the shrub to a more suitable location.
If the issue is due to improper care or minor pests, homeowners may be able to address it themselves. However, for more serious diseases, complex pest infestations, or issues with the soil or environment, it's best to consult a professional landscaper or arborist. They can properly diagnose the problem and recommend the appropriate treatment to save the shrub.
