The volcanic rock dust will benefit from tastier crops and increase resistance to pest and drought. Mined from Scottish quarries the rock dust contains two thirds of non-synthetic minerals known to man. It is a more natural way of adding essential trace elements to your soil.



Can be beneficial to apply all year round except when the ground has frozen or in windy conditions. Earthworm action will benefit the effects of the rock dust as they will draw the rock dust into the soil and help release the minerals.



Can be used with wormeries to help create a mineral enriched compost. Expect healthier bigger crops with tastier fruit and vegetables. The rock dust is completely natural and organic.


Top Dressing: Spread at any time of year unless frozen or windy conditions. Recommended per annum: 0.5kg / m²(good handful / square yard) = 2tonnes / acre Booster: 2kg / m² = 8tonnes / acre.

Plant Pots, Tubs; Baskets Sprinkle level tablespoonful onto 15cm (6inch) surface diameter of compost or soil and water in as usual. Two applications per year.

Compost Activator and Accelerator: Each time you add a new layer of compost to your compost bin or pile, add a light covering over the surface that you can easily see through. Speeds up the break down and reaches higher temperatures and reduces odours.

Wormeries: Sprinkle small handful per 30cm² (1ft²) onto surface of your wormery every month. Try a small area with this amount and see the worms congregate.
Clay Soil: The principle function of the rock dust is that the minerals in it boost the living organisms of the soil ie everything from the bacteria to the worms. These will be struggling in sticky clay soil as it has the normal breathing pores will be full of water / sticky clay particles. Once the boosted soil organisms get going they will help drag humus into the clay area and break it up.
