The answer to 'shrub erosion' is that it is a common problem caused by various factors like heavy rainfall, runoff, and poor soil drainage. Symptoms include exposed roots, slumping soil, and stunted or wilted shrubs. Solutions can involve improving drainage, adding mulch, stabilizing the soil, and potentially replanting the shrubs.
Shrub erosion is often a DIY-fixable issue, but in severe cases or if the underlying causes are unclear, it's best to consult a professional landscaper. They can properly assess the situation and recommend the most effective long-term solution.
