The answer to 'retaining wall dying' is that there are several common causes for a retaining wall to fail, including poor drainage, soil erosion, and structural issues. Symptoms may include cracks, leaning, or bulging in the wall. Solutions can range from minor repairs to complete wall replacement, depending on the severity of the problem.
If the wall is only showing minor signs of wear, such as small cracks or slight leaning, you may be able to address it with DIY repairs. However, for more significant structural issues, it's best to consult a professional landscaping or masonry contractor to assess the damage and provide the appropriate solution. They can ensure the wall is properly repaired or rebuilt to withstand the pressures of the soil and weather in your area.
