Stone Warehouse Blue Slate Chippings - 40mm - Single Bag 20Kg

They are primarily used as a decorative ground cover for garden borders, rockeries, paths, and for topping raised beds to enhance aesthetics and suppress weeds.

For effective coverage and weed suppression, it is recommended to lay the chippings to a depth of approximately 40-50mm.

While not strictly mandatory, using a permeable weed membrane underneath the chippings is highly recommended for optimal weed suppression and to prevent the chippings from mixing with the soil over time.

The Blue Slate appears a paler color when dry, deepening to a rich bluish-plum color when wet. This color change is a natural characteristic of the slate.

No, these chippings are intended as a decorative top layer and are not suitable for direct planting. They should be used around existing plants or on areas where no planting is intended.

Coverage varies based on the desired depth, but a 20kg bag typically covers approximately 0.2 to 0.3 square meters at a depth of 40-50mm.

The chippings have angular pieces with a flattened profile. While generally safe for garden use, avoid prolonged or rough contact and wear gloves when handling large quantities.

Ensure a weed membrane was installed beneath the chippings. If not, carefully lift the chippings, install a membrane, and reapply. For existing weeds, manually remove them and consider using a weed killer on the membrane before reapplying chippings.

This is normal when dry. The vibrant bluish-plum color appears most prominently when the chippings are wet. They will naturally deepen in color after rain or watering.

Ensure the chippings are spread to an adequate depth (40-50mm) and that the area has adequate drainage. Consider edging or borders to help contain the chippings.

A light dusting is normal from handling. Rinse the chippings with water once they are in place, or before spreading, to wash away any loose dust.
