The coir tree rings are made from half an inch of thickly woven, self-bound sustainable coconut fiber which means they won't fall apart. The tree rings can be used as mulch mats, to control weed growth or as a plant cover. The biodegradable coir allows air, water and nutrients to permeate through, while suppressing weeds. They're light and easy to slip around a tree trunk or even smaller plants. For a larger center, just trim it with a scissor.
