Big Foot Granular Instructions / Analysis Sheet

Big Foot Granular BioChar Worm Castings

Big Foot Granular is perfect for transplanting. Mix in soil. Granular needs to be applied near the roots of the plant. Do not apply granular on top of soil.

Our Big Foot blend is a new take on mycorrhizae. Most products on the market don't utilize all of their potential. We created Big Foot to be efficient. During the first stage of development, we started to experiment with the carriers of our product. It was quickly discovered that we could utilize our carrier as a powerful tool. This was the “lightbulb" moment for us. We replaced most of the traditional inert carriers found in other products with carriers that actually stimulate and promote the mycorrhizae. This has been a game changer. By combining the world's most powerful mycorrhizae and high performing ingredients as the carrier, Big Foot has mycorrhizae colonization levels that are unrivaled.

Application of Big Foot Granular

Spread Granular evenly around the bottom and sides of the planting hole. Ensure thorough coverage of product to maximize root contact.

Planting : Sprinkle 1/4 tbsp of granular around the planting hole. Place plant into the planting hold and backfill with soil.

Mix with Soil : Mix 3 tbsp of granular per cubic foot. Mix 3-4 lbs of granular per cubic yard of soil.

What is Big Foot Mycorrhizae?


Accelerates plant strength, greatly increases the surface absorbing area of roots, increases efficiency in nutrient and water absorption, increases plant growth.


Contains beneficial vitamins and minerals including potassium, accelerates growth, provides natural growth hormones(Auxin, gibberlins, and cytokine)

Micronutrients & Trace Minerals

Contains over 70 trace minerals, improves root system growth and crop yields, bigger and healther fruits, improves nutrient depleted soil

Worm Castings

Slow releasing and extremely rich organic fertilzer, provides food for garden plants, humus in castings extracts harmful toxins, fungi, and bacteria

Humic Acid

Increases nutrient uptake, increases drought tolerance, promotes seed germination, acts as a root stimulator


Increases water retention, increased number of benficial soil microbes, increased soil fertility, reduced leaching of nitrogen in ground water

What is Mycorrhizae?

"Mycor" "rhiza" literally means "fungus" "root" and defines the mutually beneficial relationship between the plant and root fungus. These specialized fungi colonize plant roots and extend far into the soil. Mycorrhizal fungal filmaments in the soil are truly extensions of root systems and are more effective in nutrient and water absorption than roots itself. 95% of the worlds plants form a relationship with mycorrhiza.

What does Mycorrhizae do for plants?

These Mycorrhizal fungi increase the surface absorbing area of roots 10 to 1,000 times, thereby greatly improving the ability of the plants to use the soil resource. Estimates of amounts of mycorrhizal filaments present in soil associated with plants are astonishing. Several miles of fungal filaments can be present in less than a thimbleful of soil. But mycorrhizal fungi increase nutrient uptake not only by increasing the surface absorbing area of roots. Mycorrhizal fungi release powerful enzymes into the soil that dissolve hard-to-capture nutrients, such as phosphorus, iron and other “tightly bound" soil nutrients. This extraction process is particularly important in plant nutrition and explains why non-mycorrhizal plants require high levels of fertility to maintain their health. Mycorrhizal fungi form an intricate web that captures and assimilates nutrients, conserving the nutrient capital in soils.

  • Improved nutrient and water uptake
  • Improved root growth
  • Improved plant growth and yield
  • Reduced transplant shock
  • Reduced Drought Stress
  • More flowers + fruit

What other functions do Mycorrhizal fungi perform?

Mycorrhizal fungi are involved with a wide variety of activities that benefit plant establishment and growth. The same extensive network of fungal filaments important to nutrient uptake is also important in water uptake and storage. In non-irregated conditions, mycorrhizal plants are under far less drought stress compared to non-mycorrhizal plants. Mycorrhizal filaments also produce humic compounds and organic “glues" (extra cellular polysaccharides) that bind soils into aggregates and improve soil porosity. Soil porosity and soil structure positively influence the growth of plants by promoting aeration, water movement into soil and root growth and distribution. Many practical benefits can be expected from using Mycorrhizal fungi in common practices.
