The Martins Pine Bark Coarse Mulch is a natural, brown pine bark mulch that maintains its color. With a size of approximately 10mm, it is suitable for mulching garden beds, pots, trees, and shrubs. This mulch serves as a protective barrier, effectively reducing weed growth in garden beds while also breaking down over time to add organic matter and nutrients to the soil. It conserves water, minimizes evaporation, suppresses weeds, and protects plants from extreme temperatures. Additionally, this long-lasting, decorative mulch is odorless and safe to use.
