Made from shredded wood, bark products, which are typically dyed black using natural, non-toxic colourants like carbon-based dyes or iron oxides. Benefits: Decomposes over time, adding valuable organic matter and nutrients to the soil, which improves soil health. It helps suppress weeds and retains soil moisture. Lifespan: Generally lasts one to two years, with the color fading over 9-12 months due to sun and weather exposure.
