Mulch from the shredded bark of pine trees is especially beneficial for acid-loving garden plants, such as azaleas and rhododendrons. It also adds a healthy dose of aluminum to the soil, which promotes green leafy growth. You’ll appreciate this product as it suppresses weeds, retains soil moisture, and enriches the physical condition of your soil as it breaks down. Since pine bark mulch is very lightweight, it is inappropriate for slopes, as it can be easily moved by wind and rain.
