About Us
Professional-grade fertilizer. Built for home gardeners.
GardenIQ started as a professional product.
The formulas behind our fertilizers were developed through decades of agronomic research — field-tested by golf course turf managers, commercial farms, and plant nurseries long before they were ever available to home gardeners. Our parent company, Enhanced Organics, supplied those formulas to professionals who staked their livelihoods on results.
GardenIQ brings that same science home. Sized for your windowsill, your raised beds, your lawn.
Powered by Nutrx™ Technology
Every GardenIQ product is powered by Nutrx™ — our proprietary blend of carbon complexes, humic and fulvic acids, enzymes, and amino acids designed to maximize how much of every application your plants actually absorb.
Most fertilizers put nutrients into the soil and hope for the best. Nutrx™ is built around delivery — making sure more of what you apply makes it into the plant, where it actually produces results. Stronger roots. More growth. Better color. Less waste.
Four categories. Six formulas. One system.
