About SUPERthrive

In 1940, a plant scientist named John A.A. Thomson set out to answer a question that most growers hadn't thought to ask: do plants need vitamins the same way people do? His research led to a concentrated liquid formula that combined B-vitamins with natural hormones, creating a product that helped plants grow stronger roots, resist stress, and recover from transplanting. He called it SUPERthrive.

The formula worked. Professional nurseries adopted it first, using the distinctive brown bottle with the hand-drawn label to nurse transplanted trees and revive struggling stock. Word spread through the gardening community by way of growers sharing results over fences and at garden club meetings. A small bottle became a permanent fixture on greenhouse shelves across the country.

The original formula remained unchanged for decades because it delivered consistent results. Growers reported that yellowing plants regained color within days of treatment. Transplanted trees that would normally lose leaves for weeks recovered in a fraction of the time. Indoor plant collectors found that a few drops per gallon kept tropicals lush through the dry winter months.

The biggest evolution came with the addition of kelp to the formula. Ocean-harvested kelp brought trace minerals and natural growth compounds that complemented the original vitamin complex. The enhanced formula maintained everything growers loved about the original while adding sea-sourced nutrition that soil alone couldn't provide. Growers noticed stronger root systems and improved stress tolerance across a wider range of growing conditions.

Today's SUPERthrive product line extends beyond the original vitamin solution. The Liquid Organic All Purpose Plant Food carries OMRI certification for gardeners who grow food organically. Bonsai-Pro delivers a professional-grade formula tailored to the shallow root systems and precise nutritional demands of miniature trees. Cold-pressed Neem Oil from Indian Neem tree seeds provides natural foliar care for both indoor and outdoor plants.

The company operates from the Rogue Valley in southern Oregon, where the mild climate and fertile soil create ideal conditions for testing plant nutrition products year-round. Staff members are gardeners themselves, growing everything from heirloom tomatoes to rare orchids. That firsthand experience shapes every product decision.

More than 30,000 verified reviews tell the story of rescued plants, transformed gardens, and window boxes that draw compliments from neighbors. The math remains the same as it was in 1940: one tablespoon treats 15 gallons, a small bottle lasts months, and the results show up within days. Eight decades of grower feedback confirm that John Thomson's original question had the right answer.
