This decorative product is eco-friendly as it is recycled in the UK from the roofing slate industry. The use of slate in borders and planters as a mulch greatly reduces water evaporation whilst still maintaining permeability for plants and wildlife. The blue is bold and gives a real contemporary look which can help bring your garden to life. The flat angular shape of the slate gives a stylish modern look.
