HardyGro's granular organic fertilizers combine slow-release nutrition with billions of beneficial bacteria and mycorrhizae fungi to build soil biology while feeding plants over extended periods. These dry fertilizers are designed for incorporation at planting, transplanting, bed preparation, and top-dressing established crops—providing months of steady nutrition from a single application.
The granular products include GroRocket's complete organic fertilizer formulations with balanced NPK and UltraBio's microbial inoculant shakers containing mycorrhizae, Trichoderma, beneficial bacteria, humic acids, and amino acids. All granular fertilizers contain living microorganisms that colonize root zones and remain active throughout the growing season, unlike water-soluble products that deliver a quick hit and move through the soil profile.
Granular fertilizers work differently than liquids or solubles. The slow-release formulation means nitrogen, phosphorus, and potassium become available gradually as soil microbes break down organic materials—matching plant uptake patterns and reducing leaching losses. One application at planting can carry crops through multiple growth stages without the need for frequent reapplication. The microbial component establishes in the root zone and continues working long after the initial nutrients are consumed.
Application is straightforward: broadcast and incorporate before planting, band along rows, work into transplant holes, or top-dress around established plants and water in. No mixing, no spray equipment, no measuring liquids. These products suit operations where soil incorporation makes sense—new plantings, landscape installations, garden bed preparation, or maintenance feeding of established crops and ornamentals.
