Diamond R Fertilizer Company
Serving Florida Agriculture Since 1943

The company was originally founded by the Roper family in Winter Garden, Florida where they grew citrus and sold fertilizer to other growers in the area. The <R> Brand was used on their fruit boxes as a way to distinguish themselves from other grove owners at the packinghouse. The Roper family later sold the fertilizer and agrichemical businesses to a group of citrus growers and investors from Ft. Pierce. The company grew and prospered over the years becoming the largest full service agrichemical dealer in Florida. Present day assets include 4 bulk-blending plants, agrichemical storage facilities at Ft. Pierce, Winter Garden, Okeechobee, LaBelle, Palatka, Homestead and Lake Placid, a seed harvesting and processing division, and an analytical laboratory. Annual sales total approximately $100 million, which is evenly  divided between crop protection and fertilizer products. Diamond <R> Fertilizer Co., Inc. has always been recognized for superior service, quality products, and expert technical support.
