The Enrich Bark is manufactured from 100% natural bark. The final product is mid to dark brown in appearance and is graded to 30mm for consistency and to remove oversize particles. It improves the appearance of trees and shrub beds with its mid-dark brown colour, suppressing weed development by knitting together to form a blanket over the soil surface. This helps to prevent water loss and improves plant vigour. Over time, it decays to provide a source of slow release nutrients to the soil and plant, also insulating plant roots from frost.
