The answer to 'why is my hedge erosion' is that hedge erosion is typically caused by a combination of environmental factors, improper planting or maintenance, and natural growth patterns. Common causes include heavy rainfall, poor soil drainage, excessive foot traffic, and lack of proper trimming and pruning.
Symptoms of hedge erosion include bare or thinning spots, uneven growth, and soil loss around the base of the plants. To address hedge erosion, it's important to improve drainage, add mulch, and regularly trim and shape the hedge to encourage dense, even growth. In some cases, you may need to replant or rework the entire hedge to resolve severe erosion issues.
