GARDENIQ HOUSEPLANT PROGRAM
Most fertilizers keep your plants alive. GardenIQ helps them actually thrive — professional-grade formulas designed to maximize what your plants absorb from every feeding.
Build Your Houseplant Program
Why your plants are struggling
Most fertilizers feed what's above the soil. GardenIQ starts below it. Healthy roots absorb more nutrients, support stronger growth, and keep your plants thriving — not just surviving. RhizoCarbon is built around soluble carbon and humic acids to support root development from the ground up. Your booster completes the program by supporting soil health and fueling above-ground growth. Together they address what your plants are actually missing.
THE COMPLETE PROGRAM
Your hero formula is engineered toward a specific outcome — bigger, more beautiful foliage and a thriving root system. 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 your entire collection all season. For faster results, increase within label directions — your plants will show you the difference.

Value per bottle
Container plants don't need heavy feeding — they need consistent, precise nutrition. At the recommended rate of 1 oz per gallon, a single bottle covers hundreds of individual feedings. That means more results, less waste, and a formula that lasts all season and well beyond.

Real results
My monstera seemed to double in size this year. Even though I'm not a plant scientist, the root strength must be working.
My aloe went from a tiny baby plant to a giant with 3 offshoots I had to remove and give to family.
Really like that this uses natural ingredients like kelp and molasses — feels good to use on my houseplants.
