Organic Liquid Worm Castings


At Calder Permaculture we have harnessed a unique process of working with nature, for nature – that just makes sense. We believe you need to look after the soil for it to look after you, it’s really that simple.

Worm Juice provides billions of good microbes and helpful, nitrogen-fixing bacteria to your plants and vegetables. You don’t see these good microbes in synthetic liquid fertilisers, so nothing can beat this recipe provided straight from mother nature. The Carbon content in our Organic Liquid Worm Castings product, called STIMULATOR, promotes soil structure giving greater stability – improving soil aeration, water drainage and retention, and reduces the risk of erosion and nutrient leaching

STIMULATOR is 100% natural and 100% certified organic. When given the chance, STIMULATOR will promote the return of native worms to the soil which will work hand in hand to improve the biology in your soil.

Whether you operate under organic, regenerative farming practices, or classic traditional farming- or somewhere in between – any and every one can reap the rewards of our product.

The proof is in the pudding for us, as we have spent the last 20 years turning our barren, poor quality lime/clay soil into a thriving plant oasis using Permaculture methods. We have supported the symbiotic relationship between earthworms and bacteria and used the benefits to grow just about any vegetable we desire. Read more on our about us page.
