Product Description

mychorizae powder mycorrhizae for plants mychorizae powder microrizal powder mycorrhizae powder
micorhizal fungi micorizal fungi Mycroizae Mycrorizal inoculant peas
potting soil Vermiculite hydroponic nutrients bonzai tree indoor plant fertilizer

How do you inoculate soil with Myco Supreme mycorrhizae?

Add Trifecta Myco Supreme directly to the growing medium so that the mycorrhizal spores make good contact with the plant’s roots. Set the plant and backfill. Be sure to water plants well after transplanting.

Can you use too much Myco Supreme mycorrhizae?

No, you can’t use too many mycorrhizae. Unlike some fertilizers or soil additives, it does not damage your plants if you accidentally add too much. These fungi are beneficial, and even adding copious quantities won’t hurt your plants.

How long does it take for Myco Supreme to work?

The fungi begin colonizing at once, but it takes about a month for the colony to become established. You will begin to see a noticeable difference in your plants after about the first week.

How long does Myco Supreme mycorrhizae last?

There is an expiration date printed on the package which is applicable to both opened and unopened material. It is 2 years from the date of manufacture. Once they are in the soil, they will stay there unless they’re destroyed by chlorine or sunlight.

How does Myco Supreme boost plant growth?

Myco Supreme Mycorrhizae makes plant roots longer, stronger and more efficient making your plant bigger and healthier. This creates a second root system for the plant, and this root system penetrates deeply to pull water and nutrients from the soil.

Here is why Trifecta Myco Supreme is better than the rest…

To measure the amount of living mycorrhizal fungi in their product other brands use plant root fragments called propagules. The problem is that with propagules the living fungi die off and their effectiveness is rapidly lost as these plant root pieces age sitting on the shelf. There are published reports of mycorrhizal fungi root fragments (propagules) losing their viability after only a few weeks. This means that the majority of the living fungi measured with propagules is dead in the bag within a few weeks to a month of manufacturing...Leaving the product almost useless and unable to help stimulate root growth.

Unlike most other brands, Trifecta Myco Supreme utilizes harvested living Mycorrhizal Fungi spores which are much more long-lived than propagule root fragments. Spores are the actual reproductive and survival structures produced by mycorrhizal fungi, not discarded fragments of plant roots such as propagules. Our mycorrhizal fungi spores have an extended shelf life much longer than the life of any propagule. Trifecta MYCO SUPREME mycorrhiza strain has demonstrated its superiority for effectively colonizing plant roots, making for stronger and healthier plants. Repeated trials have been conducted against other major producers of mycorrhiza in North America showing a root colonization rate up to 25% higher proving it’s superiority in the marketplace.With MYCO SUPREME, you can rest assured, you are getting what you pay for. Do not be fooled by other companies selling you dead powder in a bag. Every bag of Myco Supreme Premium Mycorrhizal Fungi comes alive, fresh, and super potent… guaranteed.

Myco Supreme Application Directions: Simple and Easy to Use for Explosive Root Growth: Add Trifecta Myco Supreme directly to the growing medium so that the mycorrhizal spores make good contact with the plant’s roots. Set the plant and backfill. Be sure to water plants well after transplanting. If transplanting into rockwool, poke several small holes in the bottom of the transplant hole in the large cube and add Myco Supreme into the hole shaking the material down into the extrusions.

Raised Beds: Simply add 1 Teaspoon directly to the roots of your plant or in each plant hole prior to transplanting so that the roots are in contact with the product. Be sure to water plants after transplanting. Outdoor Transplants Directly Into Ground: 2 Tablespoons or more as needed such that a fine dusting of MYCO SUPREME covers the bottom of the hole where the plant's roots will make contact. For Soil Drench Applications: Calculate the normal amount of water and Trifecta MYCO SUPREME for an individual plant based on the container size or other characteristics described in the directions above. Slowly add MYCO SUPREME into the water with continual mixing until it dissolves and pour contents around the roots. It is recommended to treat each plant individually to get even and appropriate dosing. Trifecta Myco Supreme can be used in soil pots or beds, indoor, outdoor or greenhouses For herbs, vegetables, and fruiting and flowering plants. For all mediums only one application of MYCO SUPREME is required.

IMPORTANT NOTE: Myco Supreme should never be added to water in hydro reservoirs: For hydroponic applications we recommend that our mycorrhizal powder be applied directly to the roots wherever/ however it allows the product to make extended contact with the roots. If using rockwool the best practice would be when transplanting from starter 1” rockwool plugs into 6”- 8” rockwool cubes use approximately 1 teaspoon of Myco Supreme dust the transplant hole in the larger cube and settle the plug into the hole nesting the roots against the product. This allows the product to have extended resident contact with the roots. In hydro systems that use baskets or trays the best practice is to lightly dust the roots with the powder where they are exposed to air above the water. This will allow the product to reside with the roots for an extended period of time so that the mycorrhizal fungi can become established.

Over-water your plants? Meet your new best friend
If you’re like me, new to indoor plant growing & not experienced with how much water is too much, this product may help protect your plants. I know how it feels when you see that dry layer of soil on top…your plant is thirsty, right? Not sure? Better safe than sorry, we KNOW plants will die without water, but if there’s too much water it’ll just drain out the holes in the bottom of the planter..right?Not always…in fact you can most definitely kill your plants by over watering. I like armed that the hard way.I found this product on a YouTube video about growing sweet potato slips. At first I just used it on my first little lonely potato with stubby roots & no sprouts. Within a week I saw a difference. Within a month I had ROOTS. I got a bigger tub & put more taters in the soil with a layer of this stuff on the soil beds so it’s directly in contact with those taters. I also use it on every herb I’m growing indoors right now to protect against my habitual over watering (although I’ve got this fairly under control now).After seeing the before & after of my first sweet potato, I highly recommend this product. It only takes a little sprinkle, I’ve followed the directions on the package every time & am very happy with the results.In the pics, the first tater (only one I lifted out of the soil) is the very first one I started. I couldn’t lift the other side, roots are thicker & deeper…its anchored into the soil. I’ve taken several slips off it, they were incredibly tall. They rooted nicely & I decided to take my chances with them outside (I’m in zone 7a). I know they probably won’t make it through winter but I’m going to cover them with plastic, they’re in a raised bed with some good compost, so I figured why not try. The little slip I took the pic of accidentally came off when I was getting one of his big brothers & he’s rooting well too. Will probably end up planting some slips indoors until spring, I have a bunch of empty 18 gallon Rubbermaid totes I intend to use.

5.0 out of 5 stars Effective, efficient and worth every penny - highly recommended
Reviewed in the United States on June 8, 2023
Best thing I did for my garden! All my plants are like on steroid, and that too using what nature has been doing millions of years.

I have a brand new house with almost 100% sand under the sod. Builder shoddily put landscaping plants with pine bark mulch but without proper soil or compost. After thorough research I bought Trifecta's Mycos Supreme. It appeared expensive but is super concentrated. Within 3-4 weeks neighbours started commenting on my garden. Hibiscus was lush green and flowers numerous / colourful. I removed the mulch and could see fungi spreading out to collect nutrients. Then I applied this fungi to my new vegetable raised garden. Within weeks, plants were on steroids! It is producing more vegetables than I can possibly eat!!

For those who are not seeing success with this, I recommend they have mulch over the soil, provide some compost, keep the soil moist and feed fertiliser / nutrients - both organic or inorganic works. Fungi will efficiently break and provide nutrients to the plants. Some of my vegetables/ vines grow 6-8 inches a day! This too in sand!!

When I ran out of this product, I could not get replacement in time so tried other alternative which was available and nearly half price - regretfully one gets what they pay for. Though it worked, it was not as effective as Trifecta. I have invested a lot in my garden. This product has unquestionably worked and worth every penny!

Highly recommended. Before and 6 months after pictures shared for comparison.
