O’Neills Celtic Plum Slate Mulch

The top selling stone in Munster!

We have a plum crushed 20mm chip which is more suitable for driveways.

Quarried down in Ovens, our plum slate will give the perfect touch of colour to your garden now!

Perfect for shrubberies and rockeries as the natural colours blend very well with plants and shrubs.

Plum Slate Mulch is ideal for Water Features as when wet creates a beautiful deep plum colour. When the stone is wet it brings out a more vibrant plum colour.

Our Plum slate is available for collection in either 25kg bags, loose or in 1 Tonne Bags at our Quarry in Ovens P31AH05

It also can be delivered loose or in 1 Tonne bags.

The vibrant plum colour of the slate is very modern and is a popular choice for both domestic and commercial landscapes.
