Eight decades of helping growers nurture healthier, more resilient plants.
SUPERthrive started in 1940 as a single vitamin formula developed for professional nurseries. The founder believed plants needed vitamins the same way people do, and created a concentrated liquid that could be added to any watering routine. That original bottle, with its distinctive label, became a staple in greenhouses and garden centers across the country.
Today the formula includes kelp, adding ocean-sourced minerals and natural growth compounds to the original vitamin complex. The product line has expanded to include organic plant food, professional bonsai nutrition, and cold-pressed neem oil for natural leaf care. Every product reflects the same principle: give plants the nutrition they need, and they'll do the rest.
Thousands of plant parents and professional growers share their results.
I've used Superthrive for a few months now, and the impact on my plants has been remarkable. Stronger roots, more vibrant leaves, and healthier plants across the board. Even my finicky plants respond when I add it to their watering routine. A small amount goes a long way, and the results showed up within the first two weeks.

Product as described. Superthrive has kept my plants healthy and looking fantastic for decades, as part of my care routine for tropical indoor plants and summertime perennials. They resist shock and propagate well with this product. Tried and true.

I had one African violet that looked unhealthy for five months straight. Nothing I tried helped. After one dose of Superthrive, the leaves firmed up overnight and the color improved dramatically. Several other young plants that were struggling got healthy and better established within days. My established plants seem stronger too.

We use this for all our outdoor container plants all summer. The plants stay healthy and beautiful. Neighbors constantly tell us we have the most beautiful yard in the subdivision. Worth every penny for the volume of flowers and greenery we get from a single growing season with this product.

We stumbled onto this product and it transformed our window boxes. Two full eyedropper squirts per gallon made our hostas, tomato plants, and flowers explode with growth. The vitamin solution absorbs fast and the results show up within a week. Our garden looks better than it has in years.

I struggled with my bonsai for years. After only two applications of Bonsai-Pro, they started thriving and blooming. A little goes a long way and the formula delivers balanced nutrition directly to the shallow root systems. My juniper turned noticeably greener within a week. I recommend this to every bonsai grower I meet.

I caught the plant bug last year and now have over forty houseplants. I keep rescuing dying ones from local stores. The before-and-after results with Superthrive are striking. My violets doubled in size in three weeks. A bonsai tea tree that was three-quarters dead sprouted bright green leaves within one week of treatment.

I swear by this fertilizer. I've used it for several years on my vegetables and flower beds. It's fish emulsion so it has a strong smell, but the results speak for themselves. My plants are bigger and produce more blooms than anything else I've tried. The organic certification matters to me since I grow food my family eats.

Mix the cold-pressed neem oil with a mild dishwashing soap to emulsify it, then spray on plant leaves as a foliar treatment. Apply to both indoor and outdoor plants. Avoid spraying in direct sunlight for best absorption and to prevent leaf burn.
Bonsai-Pro was formulated specifically for the shallow root systems and precise nutritional needs of bonsai trees. While it's safe for other plants, the concentration and nutrient ratios target bonsai growth patterns. For general plants, the original vitamin solution or organic plant food deliver broader benefits.
The formula is super concentrated. A 4 oz bottle treats hundreds of gallons of water and lasts months of regular use for most home gardeners. Best results come from using it within two years of purchase. Larger sizes offer better value for growers with more plants.
Yes. The vitamin solution integrates with hydroponic reservoirs and soilless growing media. Growers add it to their nutrient mix at the standard dilution ratio. The Bonsai-Pro formula also works in soilless media for specialized growing setups.
Many growers report that stressed, wilted, and yellowing plants recover after treatment. The vitamins and kelp support cellular repair, helping plants regain turgor and color. Results depend on the severity of the stress, but the formula has a strong track record of reviving struggling plants.
