Neem Granules combine the natural benefits of Neem oil with VolcaMin Zeolite* a mineral formed from volcanic ash, rich in silica and trace minerals. Together, they provide both nutrition and soil detox benefits.
How It Works
*What is VolcaMin?….. The mineral from the Volcano, (Zeolite Clinoptilolite), is 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 traditional agchem liquid fertilisers. The hard granules do not break down when swept or handled. Properties of our Volcamin:

First time owning lawn. Gave the team at plant doctor a ring and they supplied me with a wealth of information. Products turned up quickly.
Will definitely be getting more 8 weeks difference been using stimulizer, activ8mate, soil wetter, seaweed secrets and champion fertiliser. Was super fast delivery.
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!
