Beneficial mycorrhizal fungi work in partnership with plant roots, extending their reach into the soil to boost nutrient and water absorption. This 8-strain endomycorrhizal blend in a fine, micronized carrier is designed for easy application in gardens, orchards, lawns, and nursery settings. By enhancing root efficiency, these fungi help plants grow stronger, resist stress, and thrive in challenging conditions such as drought or nutrient-poor soils.
The fine powder can be applied in multiple ways—dust directly onto transplant roots, coat seeds before planting, mix into potting soil, or dissolve in water for drenching seedlings or established plants. One 1.5 lb jar treats up to 500 large trees or shrubs, 5,000 smaller plants, 5,000 square feet of lawn, or roughly 3 acres of seed. Its recloseable design preserves freshness for up to two years.
Ideal for organic and sustainable growing systems, mycorrhizal fungi naturally improve phosphorus uptake and overall soil health, reducing reliance on synthetic fertilizers. This encourages a balanced soil ecosystem, fostering long-term productivity and resilience for both home gardeners and small-scale farmers.
