Did you know that some of the most fertile soils can be found around active volcanoes? Igneous rocks such as basalt have a high mineral content as well as providing nutrients. For this reason, basalt (also known as rock dust) is an excellent soil improver. Gardening Naturally's Volcanic Rock Dust is mined not from a volcano but from quarries in Scotland. It's a natural and organic way to add essential trace elements to your soil, which can only enrich soil health and lead to thriving crops. It can also lead to increased resistance to pests and drought.
The rock dust is beneficial to apply all year round, except when the ground has frozen or during windy conditions. Earthworms can enhance the effect by drawing it further into the ground and helping to release the minerals as they do so. Volcanic rock dust can be used with wormeries to create a mineral enriched compost, while it's also an excellent way of breaking up sticky clay soils.
How To Use
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.
