Diamond R Fertilizer is a trusted brand that has been serving the agricultural industry since its foundation in 1943. Originally started by the Roper family in Winter Garden, Florida, the company initially focused on supplying fertilizer to citrus growers in the Central Florida area. The <R> Brand became their symbol of distinction among other grove owners.

In 1974, a group of Indian River District citrus growers acquired Diamond R with the aim of addressing the needs of their own citrus operations. With the construction of a warehouse facility in Ft. Pierce, the company realized they could provide high-quality products and expertise to growers along the Indian River.

Over the years, Diamond R expanded its reach, acquiring other fertilizer companies and establishing additional service locations across Florida. Today, they boast seven full-service warehouse facilities, two blending locations, and a dedicated sales team that can create customized fertilizers and agronomic programs to meet the demands of various agricultural operations.
