“We have used Harrell’s POLYON® Fertilizer for over 20 years. I feel like the block we had it in during the 2015-2016 strawberry season was one of the best blocks of strawberries in Hillsborough County, Florida. I stand by the product and will be using it again this year.”

-Matt Parke, Owner | Parkesdale Farms
