Worm castings are a brilliant all-natural soil conditioner: not only do they contain macro nutrients, but they are also abundant in micro nutrients, minerals and trace elements (plus worms refine these to their most plant usable form).

As worm casts on their own are slightly alkaline, our Wormcast mix has been enriched with a small amount of peat-free ericaceous compost (to reduce the ph) as well as bone meal and wheat bran to increase phosphorous levels. Its therefore different to all other worm castings available on the market - its wonderful stuff!

Our wormcasts are a lovely, balanced fertiliser that provide your substrate with a rich source of plant available nutrients and humus.

Benefits of using this product

This is a general purpose, organic amendment: it can be blended with your substrate when doing your initial mix, or used as a top dressing at the vegetative or flowering stages of your plant’s life.

    How to use it

    Use it as a top dressing: add it to the top of your growing medium and water in well after application.

    Many customers also add our wormcasts along with some Rockdust as this boosts the humus and mineral content of the substrate.


    Soil: Up to 2 tbsp per gallon of substrate as additional nutrients & humus in vegetative or flowering stage. Coco: Double the soil quantity.

    [Please note: unfortunately our 5L bags are the only items in our range that are not compostable: we cannot find a compostable bag that is big enough - as soon as we can, we will use it].
