The answer to 'why is my hedge' is that there could be several common causes, including improper pruning, pests, disease, or environmental stress. Symptoms may include discolored, thinning, or dying foliage, irregular growth, or an overall unhealthy appearance. To address the issue, it's important to first diagnose the underlying cause and then take the appropriate corrective action.
If the hedge is experiencing minor issues like overgrowth or minor pest/disease problems, homeowners may be able to resolve the problem with some DIY pruning, trimming, or the application of targeted treatments. However, for more significant problems or if you're unsure of the cause, it's best to consult a professional landscaper or arborist who can properly assess the situation and recommend the best course of action.
