Professional-grade vegetable garden fertilizer
Grow a vegetable garden that actually delivers.
Most fertilizers promise bigger harvests. GardenIQ is built to deliver them — professional-grade liquid formulas designed to maximize what your vegetable garden absorbs from every feeding.

Why your garden isn't performing
Most vegetable gardens underperform. Not because of the gardener — because of the fertilizer.
Most fertilizers give your plants a quick nitrogen hit and call it done. GardenIQ goes deeper. High Yield delivers a fish emulsion base with precise nutrient ratios built specifically for vegetable production — targeting bigger fruit and vegetables, not just more plant growth. Your booster adds the micronutrients and carbon compounds that support nutrient availability in the root zone. Together they replicate what commercial farms use — in a bottle made for your backyard.
THE COMPLETE PROGRAM
The complete vegetable garden program — growth formula + booster
Your hero formula is engineered toward a specific outcome — bigger fruit and vegetables — not just more plant growth. Your booster completes the program by supporting soil health and filling the nutritional gaps your hero formula can't address on its own. Together they work in a way neither can alone.
One quart feeds a standard garden bed for a full growing season. For even bigger harvests, increase within label directions.

Value per bottle
Enough for a full growing season — and then some.
Vegetable gardens benefit from heavier feeding than container plants — bigger plants, more root volume, higher nutrient demand. At the vegetable rate, a quart covers a standard 10-plant garden bed for a full season.
Pint
~6
full feeding sessions for a 10-plant bed — good for a mid-season top-up or smaller gardens
Quart
~12
full feeding sessions — covers a standard 10-plant bed for the full growing season
Half Gallon
~25
feeding sessions — push the rate heavier, run a bigger garden, or feed through two seasons
Based on 2 oz per gallon, 1 quart of final solution per plant per feeding, 10-plant garden bed.
Our proprietary technology
Why GardenIQ works: Nutrx™ technology
Every GardenIQ formula is powered by Nutrx™ — a proprietary blend of carbon complexes, humic and fulvic acids, protein complexes, and amino acids developed through decades of professional agronomic research. Most fertilizers sit in the soil. Nutrx™ is designed to maximize how much your plants actually absorb — so you see more results with less product, and dramatically reduced burn risk.

Real results
What our customers are saying
So many tomatoes I was eating homemade tomato sauce for months at the end of the season.
Used this alongside High Yield on my tomato garden and the harvest was unbelievable.
Applied the fertilizer to my plants last week and the plants have doubled in size.
