The answer to 'mulching dying' is that mulch can become matted, compacted, or depleted over time, leading to issues for plants. Common causes include excessive mulch depth, poor drainage, and lack of replenishment. Symptoms include wilting, yellowing leaves, and stunted growth. Solutions may include aerating the soil, removing excess mulch, and adding fresh mulch as needed.
While some mulching issues can be addressed through DIY efforts, it's best to call in a professional landscaper if the problem is severe or you're unsure of the root cause. A professional can diagnose the issue, make recommendations, and properly maintain your mulch to keep your plants healthy.
