About this product
More blooms. Longer season. Less effort.
BlossoMax is a professional-grade liquid fertilizer formulated specifically for flower gardens. While most fertilizers focus on foliage, BlossoMax is built to maximize bloom production — more flowers, deeper color, and an extended season.
Powered by Nutrx™ technology, it delivers nutrients in a form flower roots can absorb immediately, supporting both the root system and the above-ground growth that makes your garden worth looking at.
Works across annuals, perennials, roses, and container flowers. Pair with a booster for the complete flower garden system.

The science
Why BlossoMax works: Nutrx™ technology
Every GardenIQ formula is powered by Nutrx™ — a proprietary blend of carbon complexes, humic and fulvic acids, enzymes, 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.
