Features

Mycorrhizal Fungi and Your Plant

This quick video will give you a better understanding of what Mycorrhizal Fungi is and how it can help your plant. This remarkable symbiotic relationship will work wonders for your garden.

How Does It Work?

Once joined with the plant this fungi will travel through the soil creating a truly massive root system. This 'hybrid' root system is highly efficient at finding nutrients from places where a plant's root cannot travel, releasing soil bound chemicals, including those from our trusted fertilisers, and transporting these back to its partner, a beneficial relationship that will persist throughout the life of the plant. A healthy plant with an established root system in a functional soil needs less intervention, chemical or physical.

Supported by the Royal Horticultural Society

Rootgrow™ ericoid contains ericoid and arbuscular mycorrhizal fungi that are completely natural and plant-friendly.

Rootgrow™ ericoid is perfect for use on Rhododendrons, Azaleas, Camellias, Heathers, Blueberries and other acid-loving ericaceous plants.

RHS Gardeners endorse rootgrow™ because rootgrow™ treated plants establish better with greater vigour, replant more successfully, have better developed root systems and cope better with drought conditions.
