Southern Florida orange farmers turn to other tropical fruit trees to diversify crops

Florida's famed orange production started in the 1830s, when farmers began shipping their citrus nationwide by rail. The state's orange industry continued to flourish until the mid-2000s, when Huanglongbing, a bacterial disease, decimated groves throughout the state. Since then, orange growers have been working to diversify their crops by replacing orange trees with other tropical fruits that thrive in the region's hot, humid climate.

The work of botanists at the University of Florida's Tropical Research and Education Center (TREC) is helping citrus growers go beyond oranges by teaching farmers how to grow other tree crops. "South Florida can support the kinds of fruits usually only found in the tropics," reports Diana Kruzman for Offrange. Consumer interest and advances in plant breeding have the region's tropical fruit business "booming."

Even with the steep dip in crop yields, oranges remain Florida's top fruit crop, but the "tropical fruit industry, which consists of higher-value crops like avocados and mangoes, as well as more niche fruits like starfruit and guava, isn’t far behind," Kruzman explains. TREC researchers are "working to introduce other varieties of tropical fruits, such as papayas and dragonfruit."

Meanwhile, farmers are tasked with developing bigger consumer markets for their growing list of exotic fruits. "So far, many customers have come from immigrant communities around the U.S. who already know about niche tropical fruits and are willing to pay a premium to ship them quickly," Kruzman adds. 

Domestic mango growers already have one marketing advantage -- their mangoes are likely to taste better because they aren't subject to USDA fruit screenings. Kruzman explains, "All mangoes shipped into the U.S. must be disinfected to prevent foreign pests or diseases from entering the country. . . .That process involves either boiling the fruit or zapping it with radiation, which tends to leach out nearly all of its flavor."
