Big Foot Ecto-Mycorrhizae | 2oz

Ecto Mycorrhizal Spore Inoculant for Trees, Shrubs & Perennials, 2oz

Trees, shrubs, and other perennials rely on a different type of mycorrhizal partnership than most annual vegetables do, and a generic endo-mycorrhizal product doesn't serve that root biology as well. Big Foot Ecto-Mycorrhizae packs over a billion ecto mycorrhizal spores in every gram, forming the symbiotic relationship that extends root reach into surrounding soil for water and nutrients.

This 2oz size suits home growers, container gardeners, and anyone transplanting a smaller number of trees, shrubs, or perennials.

Key Features & Benefits

• Over a Billion Spores Per Gram — a concentrated count of ecto mycorrhizal spores in every gram of product.
• Extends Root Reach — the fungal partnership helps roots access more of the surrounding soil for water and nutrients.
• Simple Application — sprinkle or work into the root zone at planting or transplanting.
• Made in the USA — formulated and packaged in the United States by The American Root Company.

Who Should Use Big Foot Ecto-Mycorrhizae

Ecto-Mycorrhizae suits growers transplanting trees, shrubs, or other perennials who want to support root establishment from the start, whether working with a handful of plants or larger plantings depending on the size selected.

About Big Foot Mycorrhizae

The American Root Company makes the Big Foot Ecto-Mycorrhizae line and was founded in 2016 by Zack Amaranthus. Its products apply more than 30 years of mycorrhizal fungi research from Dr. Mike Amaranthus, Zack's father, whose research history — rather than the company's own age — underlies Big Foot's formulas.

Frequently Asked Questions

What is ecto-mycorrhizae, and how is it different from the endo type?

Ecto-mycorrhizal fungi form a sheath around fine root tips rather than growing inside root cells the way endo mycorrhizae do, and they partner mainly with trees, shrubs, and certain perennials rather than most vegetables and annuals. Matching the right mycorrhizal type to the plant is what makes an inoculant effective.

How many spores are in this product?

This product contains over a billion ecto mycorrhizal spores per gram. That concentration is intended to give roots a strong initial exposure to the fungal partner at transplanting.

When should I apply it?

Apply at planting or transplanting so the spores make direct contact with developing roots. That's when roots are most receptive to forming the symbiotic relationship.

Is this made in the USA?

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