  • Why is Living Earth Compost so good?

    Living Earth Compost is made from only the best ingredients - clean, green organic material. It is brewed to perfection, then thoroughly tested so we know it is good.

  • Where can I buy Living Earth products?

    We sell our 40L bags and landscape yard products in selected stockists, see here for more details. We also deliver bulk bags of our products in selected Auckland regions. Simply head to one of our bulk bag product pages to see if we deliver in your area.

  • How does Living Earth Compost become 100% weed-free?

    Thanks to the activity of all the worker bugs breaking down the material in the composting process, the temperature quickly reaches above 55 degrees. After three days at this heat all weed seeds are killed.

  • Is there a qualifying standard for compost produced in NZ?

    Yes, there is. Living Earth Compost conforms to NZ standard 4454:2005, a standard that provides assurance that all composted matter is safe to use for the home gardener. The standard sets a quality level that Living Earth exceeds in the compost it produces.

  • How does Living Earth test its compost?

    We test every batch of compost at our on-site lab and with growth trials to ensure quality standards are met with the plants growing healthily. Other independent lab tests are performed to check levels of nutrients and to ensure the compost meets NZ standards.
