Our natural pine mulch but just fancier. Black mulch is dyed naturally with charred carbon, is pet-safe, non-toxic, and completely biodegradable. Adding this to your gardens will keep your plants’ roots protected and help them to retain moisture and control weed growth. The black colour is stable and won’t readily wash away- retaining its colour for quite some time. This mulch adds organic matter to soil through decomposition, maintains soil moisture and suppresses weed growth. Great for enhancing garden beds or landscape features.
