Vital Roots Granular - Mycorrhizal Inoculant
Build Stronger Roots & Unlock Nutrients with Beneficial Mycorrhizae
Vital Roots Granular – Mycorrhizal Inoculant is a certified organic, granular mycorrhizal amendment designed to dramatically improve root development, nutrient uptake, and overall plant health. Formulated with a vigorous species of beneficial fungi, this inoculant works directly in the root zone to establish long-lasting mycorrhizal colonies that support plants throughout their life cycle.
The active fungus, Rhizophagus intraradices (formerly Glomus intraradices), forms a symbiotic relationship with plant roots—extending the effective root system far beyond what roots alone can achieve. This expanded network allows plants to access more water, phosphorus, micronutrients, and minerals already present in the soil, leading to stronger growth and improved stress resistance.
Vital Roots Granular is best applied at transplanting, when roots are most receptive to colonization. Continued applications help expand and reinforce mycorrhizal populations over time, creating healthier soil biology and more resilient plants.
