Potash, also known as potassium, is one of three major components in turf fertilizers. Nitrogen and phosphorus make up the other two. The purpose of potash is to strengthen the root system of the plant giving it a strong base, much like the foundation of a building. If the foundation, or root system in this case, is weak then the plant above will never reach it’s full potential. Tropicare Termite and Pest Control incorporates potash into our lawn fertilization program throughout the year to ensure our customers lawns reach their full potential.
