Superthrive is great stuff. It is not a fertilizer or anything like that, it is a liquid root hormone and vitamin that is for transplanting your plants. I have used thrive for 18 years, and have not lost but one transplant in all that time, and it was because I was out of "thrive" and was late getting it to the plant. My use of thrive is 1/2 cap to 2 or 3 gallons of water, and use it at the beginning of spring when plants awaken, and are developing new roots, or during transplant when it is ideal. It is not for watering your plants with, but rather a feed you can give 2 or 3 times a year for your plants well being, and for root development. Killer stuff to use.
