Bio/Organics Endomycorrhizal Inoculant (3 lb)

Beneficial mycorrhizal fungi form a symbiotic relationship with plant roots, extending their reach into the soil to improve nutrient and water uptake. This micronized blend contains eight proven endomycorrhizal species in a mineral-based carrier, making it easy to apply in gardens, orchards, lawns, and nursery production. By supporting a healthy root microbiome, these fungi help plants establish faster, grow more vigorously, and better withstand environmental stresses such as drought, poor soil fertility, and transplant shock.

Application is simple and versatile—dust directly onto roots during transplanting, coat seeds before planting, mix into potting soil, or dilute in water for a root drench. Each 3 lb jar treats approximately 1,000 large plants, 10,000 small plants, 10,000 square feet of lawn, or 6 acres of seed. The resealable container preserves product quality for up to two years.

Suitable for organic and sustainable growing, mycorrhizal inoculants naturally boost phosphorus uptake and enhance soil structure, reducing the need for synthetic fertilizers. This supports long-term soil health and productivity, making it an excellent choice for both home gardeners and small-scale farmers.
