What do the three numbers on the bag refer to?
All fertilizers are described in terms of N-P-K value, or the amount of Nitrogen-Phosphorus-Potash in each bag. Nitrogen is primarily responsible for the color and growth of the plant. Phosphorus is beneficial for the development of the plant and root system, while Potash is necessary for proper seed development and improving stem strength. In addition to N-P-K, Nature Safe consists of a host of trace minerals, micronutrients and biostimulant sources to provide balanced nutrition for your soil and lawn.
