What is NPK on fertilizer labels?
Don’t be intimidated by the three-number code on bags of fertilizer. It indicates the levels of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. Nitrogen is responsible for the intensity of the color green in the plant. Phosphorous is good for maintaining the root system as well as the plant’s blooming and fruiting. Potassium is necessary for the general vitality of the plant. You can read our article for more information about NPK.
