Mycorrhizae are a fungus which live in a symbiotic relationship with plants. They exist as very tiny, even entirely microscopic threads called hyphae. The hyphae are all interconnected into a network called a mycelium web, which measures hundreds or thousands of miles—all packed into a tiny area around the plant. Mycorrhizae form an invaluable part of ecosystems around the world, and can be found in some form or another in just about any ecosystem. Because of this vast network, a single plant can be connected to a completely different species of plant halfway across a forest.

The key benefits that mycorrhizae provide are root system growth, improved nutrient efficiency, and increased water absorption.

Mycorrhizae connect to plants most commonly in two different ways. One form, known as ectomycorrhizae is where it surrounds the outside of the roots. The other form, known as endomycorrhizae, grows inside of the plant; squeezing their hyphae in between the cell wall and membranes of the roots.

You’re not likely to see mycorrhizae unless you have a microscope, due to their size. However every once in a while the mycorrhizae will reproduce and send up fruiting bodies producing spores also known as mushrooms.

How it works with your plants:

Plants are able to get nutrients through their roots, but they have a limited ability to do so as their roots need to be in direct contact with the soil for absorption. Fungi, get much smaller and can wedge in between individual bits of soil to cover almost every available cubic millimeter of soil. This increases surface area and allows the plants much greater access to nutrients than they could get by themselves. In return plants will take excess sugar produced in the leaves through photosynthesis and send it to the roots. From here, the mycorrhizae are able to absorb it to sustain themselves. . Mycorrhizae can also serve as a sugar delivery service when plants shuttle sugar back and forth to different plants connected into the same mycorrhizal network.

Additionally, the mycorrhizae help plants out in many other ways. Mycorrhizae can help protect plants against diseases and toxins. The common mycorrhizal network can also serve as a means for plants to communicate with each other and even warn each other against pests.


When transplanting it is recommended to use 20 – 50ml sprinkled in and around planting hole before planting.

For established plants use around 100 – 200ml worked around the plant.

For container plants use 5 – 20ml worked in top layer.
