This natural soil amendment, made from volcanic basalt, improves plant nutrition and supports resilience to drought and pests. Suitable for vegetable beds, borders, compost bins, and wormeries. Soil Improver for Fruit, Vegetables, and Flowers Enrich your garden with minerals including calcium, magnesium, iron, potassium, and phosphorus.

Volcanic rock dust supports the growth of tomatoes, herbs, and fruit while improving the soil structure for long-term plant health. Apply year-round, avoiding frozen or windy conditions for best results. Improve Soil Microbes and Clay Structure This natural amendment boosts microbial activity, enhances drainage, and supports root development.

It’s particularly useful for improving heavy clay soils, encouraging breathability and structure by feeding beneficial soil organisms. For even better results, combine with organic seaweed feed Use in Compost, Beds, and Wormeries Apply volcanic rock dust directly to beds or lawns, mix into compost heaps, or sprinkle over wormeries. It accelerates composting, reduces odours, and increases temperature.

In wormeries, it enriches compost and attracts earthworms. Benefits Reintroduces minerals to soil for tastier crops Supports strong root development and improved yields Boosts microbial life and composting processes Improves clay soil structure and drainage Safe to use in wormeries, raised beds, and pots Sizes Available Pack Size 1kg 1kg Refill Bag 2.5kg 5kg 10kg 20kg Specifications Material Volcanic Basalt Rock Trace Elements 70+ including calcium, magnesium, iron, potassium Application Rate 0.5kg per m² annually or 2kg per m² as a booster Frequently Asked Questions Can volcanic rock dust be used in wormeries? Yes, volcanic rock dust works well in wormeries. Apply a small handful per square foot monthly to enrich compost and support healthy worm activity.

Is volcanic rock dust suitable for year-round use? Yes, it can be applied any time of year except during frozen or very windy conditions. Earthworms help draw minerals into the soil throughout the growing season. How does volcanic rock dust improve clay soil? It supports the growth of soil organisms which helps break up compacted clay, improving drainage and root development in heavy soils.

Can this be used as a compost accelerator? Yes, volcanic rock dust increases microbial activity in compost piles, raising temperature and speeding up decomposition while helping to reduce odours.
