Native Americans used fish to fertilize their crops, and now the practice has come back in fashion. Our seaweed/fish fertilizer contains a wide range of micronutrients and growth promoters in addition to its official NPK rating of 3-2-2. Easy to use -- just shake well, mix with water and apply -- and completely organic. This is a balanced fertilizer; can be used for seedlings, as a foliar spray, or on established plants. Our 16 oz. bottle makes 11 gallons of solution at two tablespoons per gallon.
