Plant Success Granular Mycorrhizae (1 lb)

Just Sprinkle in at Planting Time

Plant Success Granular is a mycorrhizal inoculum that works in partnership with plant roots, extending their reach into the soil to enhance nutrient and water absorption. This powerful blend contains 13 carefully selected species of endomycorrhizae, ectomycorrhizae, and Trichoderma fungi, combined with nutrient-rich organic meals for added plant nutrition. By improving root efficiency, it helps plants grow stronger, resist stress, and thrive in challenging conditions such as drought or nutrient-poor soils.

The granular form is easy to use—sprinkle directly into planting holes, mix into your favorite planting mix, or incorporate into seedbeds and soil blends. Ideal for transplanting vegetables, fruits, flowers, turf, shrubs, and trees, it delivers long-term soil health benefits and supports strong plant establishment in gardens, orchards, landscapes, and farm plots.

Perfect for organic and sustainable growing systems, Plant Success Granular naturally improves phosphorus uptake and fosters a balanced soil ecosystem. Its combination of beneficial fungi and slow-release nutrients from feather, meat, bone, poultry, blood, and fish meals helps reduce reliance on synthetic fertilizers, promoting long-term productivity for both home gardeners and small-scale farmers.

    Excellent product

    I have used the Plant Success Organics Granular on in my garden this year and have seen a noticable difference. My plants are bigger, look healthier and I have had no transplant shock or disease problems. I also read that it improves nutrient density. Excited to taste!
