The answer to 'why is my hedge' is that there could be several common causes, including improper pruning, pest infestations, nutrient deficiencies, or environmental stressors. Symptoms may include discolored, wilting, or thinning foliage, irregular growth patterns, or even dead sections of the hedge.
Some potential solutions include proper trimming and shaping, applying targeted fertilizers, treating pest problems, or adjusting watering and sunlight exposure. DIY solutions may work for minor issues, but for more severe or complex problems, it's best to consult a professional landscaper who can properly diagnose and address the root cause.
