The answer to 'my mulching looks bad' is that there are several common causes, including using the wrong type or amount of mulch, improper application, or the mulch breaking down over time. Symptoms may include an uneven or patchy appearance, exposed soil, or the mulch looking dull and faded.
To fix the issue, start by removing any old, decomposed mulch and adding a fresh 2-4 inch layer of high-quality mulch like wood chips or shredded bark. Make sure to spread it evenly across the landscaped areas. If the problem persists or you're unsure of the cause, it's best to consult a professional landscaper who can assess the situation and provide tailored recommendations.
