Frequently Asked Questions

Why choose plum slate for your garden?

Plum slate is a popular decorative gravel because it combines strong colour with low maintenance. Decorative chippings suppress weeds when laid correctly, allowing water to drain freely, and retain moisture in soil. The angular shape helps the slate settle and stay in place, creating a neat, durable finish for any landscape project.

How deep should plum slate chippings be laid?

Lay at 40–50mm depth. For effective weed suppression, lay decorative gravel at 50mm over a weed membrane.

Does plum slate change colour when wet?

Yes. This decorative garden stone becomes darker and richer when wet. The natural purple and grey tones deepen into a bold red-plum shade.

Is plum slate good for drainage?

Yes, decorative slate chippings are free draining. The flat, angular pieces allow water to pass through easily, making this decorative stone suitable for borders, beds, and driveways with light use.
