Serving Florida Agriculture Since 1943  
Diamond R Fertilizer was originally founded by the Roper family in Winter Garden, Florida in 1943. The Ropers grew citrus and sold fertilizer to other citrus growers in the Central Florida area. The Brand was used on their fruit boxes as a way to distinguish themselves from other grove owners at the packinghouse. Today Diamond R has seven full service warehouse facilities to supply plant protection, fertilizer, pots, horticultural plastic, seed, and other specialty products. Two fertilizer blending locations with dry and liquid bulk capabilities allow the company to manufacture bagged and bulk, liquid and granular fertilizers. Diamond R’s expert sales staff can formulate a custom blend fertilizer to meet your exact needs and help you create a complete agronomic program specific to your operation.
