A longtime favorite among gardeners, growers, and plant enthusiasts, SuperThrive is a concentrated, non-toxic vitamin and plant hormone solution designed to support healthier, stronger, and more resilient plants. This trusted formula has earned a loyal following for decades, helping plants recover from stress, establish stronger roots, and thrive through changing conditions.
Powered by a unique blend of kelp-derived nutrients and Vitamin B1, SuperThrive works to support overall plant vigor while helping plants better adapt to environmental stressors such as heat, cold, wind, transplant shock, overwatering, underwatering, and other less-than-ideal growing conditions.
Whether you’re starting seeds, rooting cuttings, transplanting roses, rejuvenating stressed plants, or simply looking to encourage healthier growth, SuperThrive offers a simple boost for gardens, containers, orchards, lawns, and houseplants alike.
