Big Foot adds beneficial mycorrhizal fungi and microbes back into your soil, the same naturally occurring organisms that plants evolved with for millions of years. The result: stronger roots, less transplant shock, and more vigorous growth.
Every Big Foot formula is packed with endo-mycorrhizae spores that bond with root systems, no fillers, no fluff.
Mycorrhizae works with your existing routine, no special equipment, no complicated process.
Sprinkle granular directly into the planting hole or mix into potting media. For concentrate, dissolve in water and apply to root zone at transplant.
Mycorrhizal spores germinate and form a symbiotic bond with your plant's root tips, extending the root system up to 700x its original surface area.
Your plant accesses more water, more nutrients, and recovers faster from transplant stress. Expect faster establishment and more robust growth all season.
We've been doing this since the first scientific studies on mycorrhizal fungi. No shortcuts, no fillers.
Big Foot Gold packs 950 million living microbes into every single gram, no fillers, no inert carriers eating up your product.
Mycorrhizal fungi can expand a plant's root surface area up to 700 times, unlocking water and nutrients the roots can't reach alone.
All Big Foot products stay fully effective for up to 3 years when stored properly. Stock up without worrying about waste.
OMRI Listed for use in certified organic production. No synthetics, no shortcuts, compliant with the strictest organic standards.
Manufactured at our HQ in Grants Pass, Oregon, where Big Foot was founded and where some of the world's leading myco research happens.
From endo to ecto, soluble to granular, we have a formula matched to every plant type, from seedlings to mature hardwood trees.
Big Foot Microbes and Mycorrhizae is made at our headquarters in Grants Pass, Oregon, in the beautiful Pacific Northwest where some of the most ground-breaking research is being done on the benefits of fungi like mycorrhizae.
Our myco contains endo-mycorrhizae spores, which forms with more root systems than other mycorrhizae which can contain fillers. We've added high-quality soil amendments like kelp, biochar, micronutrients and other natural plant boosters.
Watch how our unique blend of myco, azomite, and kelp works together to build a living soil ecosystem.

Home gardeners, greenhouse growers, and landscapers across the country trust Big Foot for healthier plants.
"I've tried four different mycorrhizae products over the years. Big Foot Gold is the only one where I can actually see the difference, my tomatoes established in half the time and produced like crazy."
"We use the Concentrate formula for all our greenhouse starts. Transplant shock is basically eliminated. Our plant survival rate went from ~85% to over 97% after switching to Big Foot."
"The Ecto formula is the real deal for trees. I planted 40 Douglas firs last fall, used Big Foot Ecto on half. The difference in spring growth was dramatic. Ordering again this season."
Big Foot products are available for wholesale ordering, and we offer custom white label blends through our sister site Mycorrhizal Online.
