The answer to 'mulch erosion' is that it is a common problem caused by heavy rain, wind, or improper mulch application. Symptoms include exposed soil, thinning mulch layers, and erosion around plants and trees. Solutions include applying a fresh layer of mulch, using larger mulch pieces, or installing edging or retaining walls to prevent runoff.
Homeowners can often address minor mulch erosion with DIY methods, but significant or recurring issues may require the help of a professional landscaper. They can assess the root causes, provide expert recommendations, and implement long-term solutions to protect your landscape investment.
