DIEHARD COMPLETE is a granular mycorrhizal inoculant that delivers the full power of the DIEHARD™ biological system with a reduced gel polymer content—just 5%—making it ideal for growers and landscapers who want efficient results in a lightweight, easy-to-apply formula.

This all-in-one product introduces a diverse blend of Endo and Ectomycorrhizal fungi directly into the root zone, where they form beneficial symbiotic relationships with plants. These fungi extend the reach of roots, improving access to vital nutrients like phosphorus and nitrogen, while significantly enhancing water absorption. The result is faster growth, earlier colonization, and improved plant resilience.

DIEHARD COMPLETE is perfect for a wide range of planting applications, including flowers, containers, turf, and vegetables. It’s also well-suited for vertimulch treatments, greenhouse and nursery use, and soil or bed amendments. The granular format allows for convenient application in broadcast, spot treatments, or incorporation into planting mixes.

This granular mycorrhizal inoculant not only improves root development but also helps reduce transplant shock by energizing the soil biology and supporting early root activity. Plants establish quickly, grow more vigorously, and are more resistant to environmental stress, pests, and inconsistent watering.

Whether you’re managing a commercial nursery, preparing landscape beds, or restoring turf, DIEHARD COMPLETE offers a reliable, biologically rich solution to support plant performance naturally.

DIEHARD COMPLETE is the go-to granular mycorrhizal inoculant for horticulture professionals seeking a balanced, low-gel formula that delivers powerful root and soil benefits in a range of growing conditions.
