Big Foot Mycorrhizae Gold | 5lb

Direct-to-Root Endo Mycorrhizae Inoculant for Transplanting, 5lb

Transplant shock and slow root establishment often come down to a root zone that hasn't yet built the microbial partnerships that help plants take up water and nutrients efficiently. Big Foot Mycorrhizae Gold applies a Direct-to-Root inoculum containing 950 million living microbes of diverse endo mycorrhizae and beneficial bacteria in every gram, delivered straight to the root zone at transplant so colonization can begin as roots first develop.

This 5lb size is sized for larger gardens, multiple beds, or commercial operations that need a bulk supply of microbial root inoculant.

About Big Foot Mycorrhizae

Big Foot Mycorrhizae is manufactured by The American Root Company, founded in 2016 by Zack Amaranthus.

Frequently Asked Questions

What does 'Direct-to-Root' mean for how I apply this product?

Direct-to-Root means the product is formulated for application right at the root zone during transplanting, rather than mixed broadly through a large volume of soil. Applying it directly against developing roots gives the microbes the most immediate contact with the tissue they colonize.

What's actually in Big Foot Mycorrhizae Gold?

Each gram contains 950 million living microbes made up of diverse endo mycorrhizae species and beneficial bacteria. That diversity is intended to support colonization across a range of plant types and soil conditions.

When should I apply it?

Apply at transplanting so the microbes make direct contact with roots as they begin establishing in new soil or media. Applying later, after roots have already established without it, is less effective than applying at the transplant itself.

Is this made in the USA?

Yes. Big Foot Mycorrhizae Gold is made in the USA by The American Root Company, which also produces the rest of the Big Foot line.
