Plum Slate 20mm

Rich purple in colour, 20mm Plum Slate provides a perfect contrast to the greens, greys and browns naturally found in gardens. This modern mulch is used widely in landscaping projects to alleviate water evaporation, whilst providing a permeable surface for plants and wildlife. The smaller 20mm size is perfect for paths, as the pieces form a flatter surface to walk on. Fish friendly, our Plum Slate is suitable for use in and around water features. 


20mm slate is also available in blue, black and green.
