Used for over 60 years and recommended by dozens of books, magazines, conferences, newspapers, TV and radio shows and even 5 US Government Deprtments! Superthrive is not a fertilizer - you add Superthrive to your existing plant food to boost your plants and add vigor to their growth. Superthrive is super-concentrated -use only 1/4 teaspoon per gallon of water!

I''ve used this to revive new Japanese maple seedlings that were accidentally frosted overnight! I also use it routinely to kick start growth on newly grafted trees and newly germinated seedlings.
