Big Foot Mycorrhizae Concentrate | 4oz - Water-in-Root Inoculum

Water-Soluble Biochar & Kelp Root Drench for Transplanting, 4oz

A dry soil amendment can be hard to work evenly into an already-planted bed, which is where a water-soluble option becomes useful. Big Foot Mycorrhizae Concentrate blends biochar, worm castings, kelp, azomite, and humic acid into a liquid, water-in root inoculum that mixes into a watering can or sprayer for an easy application right at transplanting.

This 4oz size suits home gardeners and anyone transplanting a smaller number of plants who wants an easy water-in inoculant on hand.

Key Features & Benefits

• Five-Ingredient Blend — biochar, worm castings, kelp, azomite, and humic acid combined in one liquid formula.
• Water-Soluble Format — mixes into water for a simple root-zone drench rather than working a dry amendment into soil.
• Water-In Application at Transplanting — designed to be applied right when roots are actively establishing.
• Made in the USA — blended and bottled domestically at The American Root Company's U.S. facility.

Who Should Use Big Foot Mycorrhizae Concentrate

Mycorrhizae Concentrate suits growers who prefer a liquid, water-in root treatment over a dry soil amendment, whether treating a small number of transplants or maintaining a supply for a full season of use depending on the size selected.

Frequently Asked Questions

What's in Big Foot Mycorrhizae Concentrate?

It blends biochar, worm castings, kelp, azomite, and humic acid into one water-soluble formula. Each ingredient contributes differently to the root-zone environment, from organic matter to trace minerals.

How is it applied?

Dissolve the concentrate in water and apply it as a drench directly to the root zone, either at transplanting or during routine watering. Because it's water-soluble, it doesn't need to be worked into the soil the way a dry amendment does.

Can this be used at every watering?

Yes, it's designed for regular, repeated application throughout the growing season rather than a single one-time treatment. Consistent use supports ongoing root-zone activity rather than a single burst.

Is this made in the USA?

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