    Good product at a good price. No complaints.

  2. Gregory in MN

    I’ve used several brands of fungi and have been most impressed with Garden Fungi’s product. Glad to support a local business in ND.

  3. Holly Keith

    Used the product with my tomatoes a few weeks ago. They look healthy…so far so good! Shipped quickly to my home and your customer service was helpful when I wanted to ask a a question about my use case.

  4. Henry D

    I have 5 Japanese maples and 2 semi dwarf meyer lemon trees currently. All 7 are in containers and benefit from endo myco fungi. Never heard of endo until this journey and I am grateful for your company because it’s expensive to build a symbiotic relationship. All are outdoor plants.

  5. Derrek T

    Originally I used your MycoMaxx Seed Treatment for my larger operation in South Dakota, but my wife has really enjoyed using your garden product for her flowers. Happy with both your ag products and your garden products!

  6. Sam

    Use the provided tools to get the spores on the roots or seed. Seen a response within three weeks! House plants need less water and are healthier. Garden produces more and larger vegetables. Organic! Highly recommend!!

  7. TomatoMan

    It Makes Roots Explode! It creates a massive root system that shows up in your flowers & vegetables

  8. MNgardner

    My flowers look better than they ever have!

  9. Stephen Pool

    Solid product with good instructions. I was a little worried I wasn’t applying correctly, but I must have because we had great growth on our plants!

  10. Kathy Liu

    Good growing season this year. Am recommending it to my neighbors who were curious.

  11. James Nichols

    This stuff is a game-changer! My plants have never grown so fast and healthy! Will buy again. I used the inoculation method with a large plastic syringe I bought at a Walmart pharmacy.

  12. OrganicGrowersUSA

    As an organic grower, I’m very picky about the products I allow in my garden. I appreciate their effort to certify their product as organic. I’ve used this on my cucumbers, sweet corn, squash, and tomatoes…it has worked great. On my second season with MycoMaxx!

  13. Shawn

    Shipped product early in the season, was impressed. Thanks!

Q & A

I'm getting ready to start seeds for this year's garden and I'm trying Mycomaxx for the first time. I see that I can either spray seeds now or spray roots at transplant. Any opinion on which would be better? I'm assuming that sooner would be better (spray seeds). Thanks!! Kristie Gray asked on February 19, 2024

Either way will work! I would do both if you can. Spraying the seeds gets the spores into the roots upon germination so they will have more time to colonize and increase the root surface area.

What type of water should we use for mixing it, and would chlorine water affect the fungi? Jen asked on March 13, 2023

Chlorine or other water additives will not affect the fungi. They are in a dormant state and will need to be in water for an extended period(two weeks) before they will start to "wake up". Best to mix and use small amounts at a time and store the product dry.

How long can the product be stored once mixed with water? Jim asked on March 7, 2023

Once mixed in water, I would get it onto plant roots, on the seed, or in the ground within a couple weeks. It's best of you only mix up what you need because the dry product will last much longer.

Would this work for cordylines? Deborah asked on February 15, 2023

Yes, Cordylines are in the Asparagaceae family. The MycoMaxx Mycorrhizal fungi will form a beneficial symbiotic association with plants in this family. Please let us know if you have any other questions. Thanks
