Free mainland UK delivery!

Remin Volcanic Rock Dust

  • Top Dressing, for growing medium i.e Soil and/or Compost
  • Compost Improver to mix with every bag or bin of mature compost
  • Compost Activator and Accelerator for compost making systems
  • Tonic for Wormeries
  • Salt Replacement - for cars or vans if stuck in snow


Top Dressing

It is found to benefit all types and pH of soil and promote plant growth and vigour. It can be applied at any time of year and at any stage of plant growth. The only exception to this is when the ground is frozen and REMIN volcanic rock dust cannot get into the soil or when it is very windy. Simply sprinkle evenly onto soil from the edge of a spade or trowel then rake in, or let worms and weather do this for you.

Minimum Annual Dose

Apply 0.5kg per square metre, or in gardener’s terms “a handful a yard”. A 10kg bag supplies 20 square metres. This annual dose has also been seen to benefit lawns.

Booster Dose

Apply 2kg per square metre to give your soil a boost.

Top Dressing for Large Areas

REMIN volcanic rock dust can be applied to fields and parks, whether grass land or cultivated, using a Lime Spreader. Fertiliser Spinners can also be used but care has to be taken to prevent it sticking to the sides of the spinner. Salt Spreaders with a Heavy Duty Agitator are also ideal.


0.5kg per square meter = 2 tonnes per acre


2kg per square metre = 8 tonnes per acre

Compost Improver

Mix 2kg through 50 litres of compost. Works well if you mix in wheelbarrow or trug. A good handful mixed through a bucket of compost works fine

Compost Activator and Accelerator

Each time you add a new layer of compost to your compost bin or pile, add sufficient to make a light covering over the surface that you can easily see through. Gardening material is found to break down into compost faster, reach a higher temperature and odours are found to be reduced.

Tonic for Wormeries

Sprinkle a small handful per 30cm2 (1ft2) onto surface of your wormery every month. Try a small area with this amount and see the worms congregate and enjoy it!

Further Info

Mixing with Other Plant Foods

REMIN volcanic rock dust has been shown to work well with soil conditioners, animal manures and plant foods. Whilst lime can still be used to raise the pH of acid soils, we do not recommend adding it at the same time as REMIN volcanic rock dust as this reduces the effectiveness of both materials. Leave at least two weeks between both applications.
