Product Description

TNC MycorrMulti is one of the TNC Mycorr range of Mycorrhizal fungi products. It contains 15 different species of fungi, including both Endomycorrhizae and Ectomycorrhizae which makes it beneficial to most garden plants, shrubs and trees.

TNC MycorrMulti also contains natural bio-stimulants such as humic acid, derivatives of a natural marine algae (ascophyllum nodosum) and Zeolitic minerals to aid in water and nutrient retention.

Mycorrhizal fungi colonise a plants root system in a symbiotic relationship – that is to say they are beneficial to each other. For example, the fungi consumes excess carbohydrates secreted from the host plant and in turn the mycorrhizae absorb minerals and nutrients from the soil and feed them back to the host plant.

Hyphae (microscopic hairs) from the fungi encompass a massive volume of soil compared to the plants root system and are far more efficient at absorbing nutrients such as phosphates. The web of hyphae act as conduits carrying the nutrients back to the host plant so vastly increasing its nutrient uptake, ultimately leading to bigger, stronger and healthier plants.


TNC MycorrMulti is not a fertiliser and ideally it should be applied to the roots or rootball.

Transplanting container grown plants, potting on etc.
Tease plant roots from the root ball if necessary and dust TNC MycorrMulti directly onto the roots, add the remainder to the planting hole.
50g is sufficient for:-
15 ltr root ball – 1 plant
6 ltr root ball – 2 plants
3 ltr root ball – 3 plants
2 ltr root ball – 4 plants
1 ltr root ball – 6 plants

Add to the planting hole
1/2 – 1 teaspoon per plant

Bare root plants / Whips
Apply directly to the roots allow any excess to fall into the planting hole.

    Devastatingly fast acting product that visually stimulates my chilli plants within days of potting up. I can only imagine it’s down to the incredible food soil web this outstanding product is building.Your molasses turned up this morning; I’m already brewing what looks to be a powerful inoculation. Thank you.

    Well done TNC. Keep up the good work.

    Delivery was good by first class post. I am looking forward to seeing how this works on planting bare root conifers. I was delighted to find this product as I spent a long time trying to find an Ectomycorrhizal fungi for this purpose. Plant research shows that about 5% of plants (including conifers) do not respond to endomycorrhizal fungi. I am surprised that the RHS endorses another product for planting ‘tree and shrubs’ which will have little effect on this group of trees. I think the price is very good and the photos make the tub look smaller than it is.

      Hi Hanna, Mycorrhizae can indeed improve drought tolerance.
      I’ve emailed you a link to the literature.

    I Find these products essential to promoting the health of indoor grown bromeliads. I mix 1 part Mycorr Multi, Bactorr, and Tricorr. And add a flat teaspoon of this mixture per 2.5 litres of water to drench the plants and potting medium during watering. I also mix a teaspoon full of this bacterial mix, 1/1 with Fish, Blood, and Bone meal into the top soil in each pot every 4 months.

    This sounds over the top because all bacteria multiply, like yeast. Before this treatment my root systems were growing very slowly, like floppy hands in the centre of the pot. Now the root mass usually fills the entire pot, it sometimes cannot be shaken, or banged out of the pot because it’s so furry. Instead I often have to push it out from the hole in the bottom, in one spongy mass. Also my plants never get rot. Also the leaves have become shiny, succulent and more colourful, and crisp. If I fold them in half now they snap when they used to bend.
