Product Description

TNC MycorrMax is one of the TNC Mycorr range of mycorrhizal fungi products. It contains 15 different species of mycorrhizal fungi, including endomycorrhizae and ectomycorrhizae as well as 5 species of trichoderma. It also contains 13 Bacillus species – Bacteria for Nitrogen fixing, Phosphorous solublising and growth promotion.

TNC MycorrMax also contains natural bio-stimulants such as humic acid and derivatives of a natural marine algae (Ascophyllum nodosum). These include amino-acids, plant hormones – cytokinins, auxins and giberellins – also vitamins and trace elements.

The mycorrhizae and microorganisms will quickly populate and colonise the plants root zone in a symbiotic relationship, an essential part of the soil food web, transporting valuable minerals such as Nitrogen, Phosphorous, Potassium and Trace elements back to the host plant.

In addition TNC MycorrMax will induce and increase resistance to pathogens and other undesirables, not only in the root system but throughout the structure of the plant.


TNC MycorrMax 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 MycorrMax 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

    Product was recommended as potentially building resistance of rhododendrons etc. to Armillaria infrction. This is my second purchase : early days but so far encouraging.

    Great product, this is worth its weight in the way it helps to grow plants. if added just at point of germination a little goes far…i hope you all wil be impressed with TNC, i am

    tried this for the first time this year – my beans, peas and other transplants have been growing much better, especially the peas, super difference from last year lush growth and heavy yields! My tomato transplants were not even sown until June 1 and they have caught up with other people’s plants started much earlier. TOTALLY sold on this stuff!

    I find these bacterial 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 mixture plus 1/1 of Fish, Blood, and Bone meal to the topsoil of each pot every 4 months.

    This sounds over the top because all bacteria multiply, But it works! Before this treatment my root systems were growing very slowly, like floppy hands in the centre of the pot. Now the root mass usually grows to fill 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.

    I had read this product did miracles and it helped with ornamental plants and even orchids, as most of them interact with endomycorrhizae. Well, it might be ok for other plants but never, NEVER try this on your orchids. Not only it doesn’t help, but it actually kills them! I’m desperate. It was time to repot my orchids, so I repotted ten phalaenopsis and two dendrobiums in a row, as I usually do, using sterile orchid grade bark chips. This time, the difference was that I applied TNC MycorrMax as stated in the instructions, to further protect them again bad fungus. The result? The work of 4 years completely destroyed in just a week. I’m desperate. Absolutely healthy roots were consumed and completely rot within 7 days, no matter the pots were new, they had obviously been sterilized and I had watered only once after 4 days. I have never seen anything like this before and I still cannot believe I have done this to twelve of my best orchids. Fortunately, I had decided to see the results before continuing. I still have other 40 different orchids to repot among them Miltonias, Dendrobiums, Oncidiums, etc. I write this review just to let people know that my experience on orchids has been a nightmare. I repeat, it might be ok for other kind of plants, but if you care for your orchids, avoid it! The product itself is expensive, but it is nothing compared to the loss you will experience.

    I have been using this for several months now, and i have to say its fantastic. I have used it on a huge range of plants, and they all seem to benefit, from bedding plants to tropicals. I plan to use it on everything next year, sprinkling a little over the roots when they are potted up or planted out.
    Customer service/support is also spot on.

    Will try it! See re orchids that 6 out of 8 are non-mycorrhizal, may explain the bad experience Flavio above had. Any idea how Mycorriza help edible plants to find the nutrients these and thus we need? Are all plant nutrients apart from water and CO2 and N minerals?

    • Nigel Davenport

      Not all nutrients are available in the immediate vicinity of the plant roots – Mycorrhizae is better equipped to transport those minerals (namely phosphorous)
      back to the plant and directly in to it’s root system. More info here.
