Big Foot 2lb Mycorrhizae Granular

Big Foot 2lb Mycorrhizae Granular is a soil amendment and root inoculant made in the USA by Big Foot Mycorrhizae, a producer with over 35 years in the industry. It delivers fresh mycorrhizal spores from the Amaranthus Family alongside a blend of Biochar, Worm Castings, Kelp, Azomite, and Humic Acid — ingredients that work together to support root development and plant establishment. The granular format makes it straightforward to incorporate into soil at planting time or apply directly to root zones during transplanting.

Why Choose Big Foot 2lb Mycorrhizae Granular

Big Foot Mycorrhizae has been producing mycorrhizal inoculants in the USA for over 35 years. The 2lb granular is the mid-range bag size in their line — enough product to treat multiple transplants or amend a soil batch without committing to bulk quantities.

• Fresh spore production. Big Foot produces spores fresh rather than relying on stockpiled material, which matters for inoculant viability at the time of application.
• Multi-ingredient blend, not just spores. The formula includes Biochar, Worm Castings, Kelp, Azomite, and Humic Acid alongside the mycorrhizal spores. Each supports root zone biology in complementary ways — Biochar improves water retention and microbial habitat, Worm Castings contribute soluble nutrients and beneficial microbes, Kelp provides natural growth compounds, Azomite delivers trace minerals, and Humic Acid aids nutrient uptake.
• Granular format for easy application. Granular inoculants can be mixed directly into planting media, dusted onto root balls, or placed in transplant holes without the measuring precision required by liquid concentrates.
• Made in the USA. Produced domestically with 35 years of category experience, as stated in manufacturer documentation.
• Appropriate pack size for small to mid-scale grows. The 2lb bag suits home growers, small commercial operations, and anyone who wants to rotate through product before viability declines — versus a bulk bag that may sit unused for extended periods.

Best Uses for Big Foot 2lb Mycorrhizae Granular

This granular inoculant fits into any soil-based or soilless growing program where establishing a healthy mycorrhizal network at the root zone is a priority. The manufacturer specifies two main application points: mixing into soil and applying during transplanting.

• Pre-mix into potting soil or raised bed media. Blend the granules into soil before filling containers or beds so the spores are already in place when roots grow into the mix.
• Transplant hole or root ball application. Place granules directly in the planting hole or dust lightly onto the root ball when moving seedlings or established plants into new containers or beds.
• Seed germination and early propagation. Introducing mycorrhizal inoculant at the seedling stage can support root development from the earliest growth phase.
• Vegetable and herb gardens. Mycorrhizal inoculants are well-suited to fruiting vegetables, leafy greens, and herbs grown in soil-based systems where root health directly affects yield.
• Use alongside other organic soil amendments. Big Foot Granular pairs well with other root zone additives. If you are already using a microbial root inoculant like Advanced Nutrients Tarantula or a liquid root stimulator, adding Big Foot Granular at transplant gives beneficial fungi a foothold before feeding programs begin.

Usage Guidelines

Mycorrhizal inoculants work by establishing a symbiotic relationship between fungal hyphae and live plant roots. For colonization to occur, the spores must make direct contact with root tissue in a moist environment. Apply Big Foot Granular at the time of transplanting or when preparing planting media — not as a surface top-dress after planting, since spores cannot migrate through dry soil to reach roots.

• At transplant: Place granules in the planting hole or apply directly to the root ball before setting the plant in place. Water in immediately after transplanting to activate biological processes and ensure moisture reaches the root zone.
• In soil mix preparation: Blend into the planting medium at the mix stage. The granules distribute evenly through the medium, ensuring spore contact when roots develop.
• Avoid high-phosphorus conditions immediately after application: Elevated available phosphorus can suppress mycorrhizal colonization in the establishment phase. If your program uses high-P starter fertilizers, time the granular application before the first high-P feeding where possible.
• Soil and amended media only: Mycorrhizal fungi do not establish in pure hydroponic solution. This product is designed for soil and soilless media (coco, peat-based mixes) that support fungal growth.
• Storage: Keep sealed in a cool, dry location away from direct sunlight to maintain spore viability between uses.
