Leveraging technology to help you predict and manage the challenges of trying to grow a better world.

Based in Lakeland, Florida since 1941, Harrell’s is a leading producer and distributor of customized, agronomic solutions – not merely “products.” This includes nutritional solutions in both granular and liquid form to help your turf, landscape and plants grow and thrive. We also specialize in delivering solutions to help protect your world from pests, environmental threats and climate extremes. Naturally, we have production and storage facilities throughout the country to ensure timely, efficient shipments.
Harrell's celebrated 75 years in 2016. Over the years, our Core Values haven't changed. We still believe in taking care of people. With that in mind, effective midnight September 30, 2016, Harrell's became an employee owned company. Through Harrell's Employee Stock Ownership Plan (ESOP), Harrell's remains a privately owned company. Our common stock is not publicly traded on a stock exchange, so it does not have a ""ticker"" symbol. Only eligible active employees own stock in Harrell's."
