The answer to 'why is my hedge overgrown' is that hedges naturally grow quickly, especially during the spring and summer months. This rapid growth can be caused by factors like ample rainfall, warm temperatures, and nutrient-rich soil. Symptoms of an overgrown hedge include uneven or lopsided growth, branches spilling over into walkways or other areas, and an overall unkempt appearance.
The best solution is to regularly trim and prune your hedge to maintain its shape and size. This is typically a DIY task that homeowners can do themselves with the right tools, like hedge trimmers and pruning shears. However, for very large or overgrown hedges, it's best to call in a professional landscaper who has the experience and equipment to properly maintain them.
