Our Organic Microbes grow on and around your plant’s roots, creating a network that greatly extends your plant’s ability to gather nutrients. From there, a symbiotic relationship is formed. The microbes live off of the natural sugars created during the photosynthesis process. In turn, they gather water and break down nutrients, delivering them directly to your plant’s roots. And once they’re in, they’re in, and will continue to grow their network, letting you and your plant reap the benefits.

Key Features

ORGANIC NUTRIENT UPTAKE BOOSTER: Expands your plant's root surface area so it can naturally access more of the nutrients and water already in the soil
ENDOMYCORRHIZAL FUNGI SUPPLEMENT: Rhizophagus intraradices acts as a root system inoculant connecting with, and extending the reach of, your plant's entire root system
SIMPLE TWO-STEP APPLICATION: Mix well into the soil so it makes direct contact with the plant's roots, water it in, and let the biological exchange take over

How it Works

To get the most out of nutrients, plants form a symbiotic relationship with microbes. A healthy microbial network breaks down nutrients so your plant can thrive.

Living Network

Fungi build a microbial network in and on plant roots that benefits both the plant and the fungi.

Food for Fungi

Microbes feed on simple sugars (like glucose and fructose) and other carbohydrates that plants naturally create through photosynthesis.

Symbiotic Relationship

In exchange for the natural sugars, the fungi helps gather water, minerals, and nutrients for the plant.

Plant Benefits

Mycorrhizal fungi act as an extension of your plant’s root system to drastically boost water and nutrient absorption and protect against environmental stresses.

Mix In: Mix the entire packet into the soil, making sure it contacts the plant's root system.
Water Thoroughly: Water into the soil to activate.

FAQs

Soil microbes act as a root system inoculant. They form a symbiotic network around the roots, essentially extending their reach. Black Magic Organic Microbes' endomycorrhizal fungi attach to root systems and create additional pathways for nutrient and water absorption, which is why direct root contact matters so much when you apply it.
