What is VolcaMin?….. The mineral from the Volcano, (Zeolite Clinoptilolite) used in Horticulture e.g. in composts/potting mixes or growing media/or as a carrier/soil ameliorant. Also used as a Silicate Fertiliser, and are superior/excellent as a carrier for slow release natural fertilisers, e.g. holding Fish liquid, seaweed or tradtitional agchem liquid fertilisers. The hard granules do not break down when swept or handled.

Properties of OUR VolcaMin:

  1. High Absorbency: Absorbs 65% - 70% its own weight of liquid.
  2. Has broad range of Trace elements
  3. Inert: Will not react with other materials/liquids.
  4. Cation Exchange Capacity: (120 to 148CEC) for Nutrient retention, able to store and slowly release cations.
  5. Fusion Point: 1,570 deg. - 1,600 deg. centigrade
  6. Ideal pH = 6.5 (to 6.7pH)
  7. Non-Disaggregating: 
  8. Colour: Predominantly white and pink, minor grey
  9. Odour Control: absorbs, locks in and neutralises odours.



The VolcaMin minerals have been derived through in-situ from volcanic ash i.e. from a volcano.

Transformation processes have resulted in a tuff with an extremely porous structure. The high absorbencies suggest these minerals have very open frameworks. Dissolution and reprecipitation of amorphous silica has resulted in a 'welded' structure that does not disaggregate in water.



Mineralogically consists of quality Hydrated Calcium (Ca) Potassium Aluminosilicates essentially naturally amorphous silica mineral.



The 1mm-2mm Greens Grade Mini Prill grade has absorbencies that average 65 - 70% w/w.

Popular Questions

Q: How often do I need to re-apply your Neem Granules?

A: There are two components to the Neem Granules, the Neem Oil and the carrier granule which is a VolcaMin Zeolite. The VolcaMin Zeolite will last for years in the soil, so doesn’t really need to be re-applied too often maximum twice a year. The VolcaMin Zeolite will help hold water in the soil and also attract and hold nutrients, reducing wastage (leaching).

You can buy the Neem Plant Spray concentrate separately and apply it as often as every 2-4 weeks if you like.

This product is amazing! I re-potted some sad looking plants and added the neem granules, they have just come back to life looking better than ever. I've also added it to new plants for protection towards pests. I love this product so, so much!

I really like these granules for pest control! They’re easy to add to my pots and small raised beds. Just mix through the top of the soil or add to new mix. I feel it’s really working to repel my fungus gnat friends.

Can’t believe how good this is

I have been dealing with pesky bugs and this product has managed to get them under control. Had previously tried so many products that did nothing. Highly recommend

Super underlay

By: on 30 April 2019
Added the NEEM granules into my subsoil before laying due to its Cation Exchange Capacity and beneficial trace elements. The 20kg bag was more than enough to cover well over 470sqm and I still had a quarter of a bag left over. Nothing else added to the underlay apart from organics and the colour and health of the lawn was exceptional, not to mention keepin the critters away from my juvenile root system. Highly recommended to add to any turf underlay

Amazing products!! The results are excellent and the prices are even better! Postage was only 2 days as well. Highly recommended!


Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
