Landon Aquatic Fertilizer 7803 12-20-8 is a combination fertilizer developed by world renowned hybridizer Kenneth Landon and used in the International Waterlily Certified Collection and Repository in San Angelo, Texas. This high-potency formula is composed of organic and inorganic compounds that work together to get exceptional results at lower soil mass per plant, compared to other mixes. Large to average sized tropical nynphaea typically requires only 10-20 gallons of fertilized soil; small tropical or hardy lilies typically require only 5-10 gallons of fertilized soil; and marginal aquatics typically require only 1 gallon of fertilized soil for the 5 month season.

Use Directions
Follow usage instructions carefully. Combine the appropriate amount of fertilizer with soil (see table below), and fill your container 75% full. Add the tuber and fill the remaining 25% of the pot with unfertilized soil. Cover the top layer with gravel and place in the pond, preferably when water temperatures are from 60º to 90º.
