The answer to 'mulching disease' is that mulch can sometimes lead to fungal diseases in plants and lawns if not properly maintained. Symptoms may include discolored or wilting foliage, mushroom growth, or a foul odor. The main causes are excessive moisture, poor air circulation, and using the wrong type of mulch.
For minor issues, you can often treat mulching disease yourself by adjusting the mulch depth, improving drainage, and increasing air flow around plants. However, for more severe or recurring problems, it's best to consult a professional landscaper who can properly diagnose and treat the disease.
