“Complete” Fertilizers are composed of 3 major components: Nitrogen. Phosphorus, and Potassium (or simply N-P-K). Generally, fertilizer containers will have these three elements listed right on the front label (ex. 16-4-18 or 12-4-8). These numbers represent the percentage (by weight) of N,P, or K contained within that specific fertilizer. These numbers are what is important when selecting the proper fertilizer for plants. Be sure to read the label before you apply any fertilizer.
