Shamrock Decorative Bark Mini Chip - 75 Litres is a decorative natural mulch for beds and borders. It is made from screened and graded bark. Bark is a by-product of the forestry industry and is a renewable resource. This bark not only looks good in the garden but also functions as a weed suppressant that helps to protect plants and soil against weather extremes. The bark provides a superb dark natural background against which the foliage of trees and shrubs is highlighted. Plants have an excellent and very attractive background to grow and thrive in.
