Potash (K) helps plants grow strong stalks. In the same way that calcium gives people strong bones, potash gives plant cells strength.

This nutrient plays a major role in the ability of plants to tolerate stresses, such as drought, frost and attacks from pests and disease.

Potash is also essential for many of the major plant functions, including enzyme activation, protein production and photosynthesis. It also helps regulate transpiration and water-use efficiency.
