Potassium (K)

Potassium is the K in the NPK trio of macronutrients essential to all plant life. Overall, potassium (K) enhances and supports strong roots and provides healthy green top growth with sturdy stems. These plants not only develop better, but also have strong resistance to pests, diseases, and environmental stressors like cold and drought. Potassium (also called potash) achieves these results by optimizing the movement of water and nutrients through plant tissue. In addition to the aforementioned improved resistance, plants with healthy potassium levels are able to smoothly photosynthesize and will produce robust blooms, and quality fruit with vibrant color and flavor. Plants that are not getting the proper amount of potassium will be stunted and have poorly developed root systems.
