By Clint Thompson and Dale Sandlin The potential lack of satsuma mandarins this season in the cold-hardy citrus region should not discourage growers from adding to their production portfolio in the future. It just means they need to try other varieties, despite satsumas being the most commonly produced variety in the region. Jake Price, University of Georgia (UGA) area citrus …
Cold-Hardy Citrus Production: A Learning Process
Production in the cold-hardy citrus region continues to be a learning process for growers. Producers in North Florida, South Georgia and South Alabama are learning this year the price of alternate bearing for their satsuma mandarin crop. After a heavy crop load last season, production is expected to taper off quite a bit this season across the cold-hardy citrus region. …
Leaf Tissue Analysis for Cold-Hardy Citrus
Leaf tissue analysis is a key to building a good citrus fertilization program in North Florida and South Georgia, according to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers. The researchers are Muhammad Shahid, assistant professor of horticulture, and postdoc scholar Shahid Iqbal, both with the North Florida Research and Education Center. “Leaf tissue analysis determines the …
Soil Sampling Is Key to Cold-Hardy Citrus Fertilization
Soil sampling is one of two keys to building a good citrus fertilization program in North Florida and South Georgia, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers wrote recently. The authors are Muhammad A. Shahid, assistant professor of horticulture, and postdoc scholar Shahid Iqbal, both with the North Florida Research and Education Center. Shahid and Iqbal …
Extremely Low Satsuma Supply Expected This Season
Fruit is scarce this season on satsuma trees in the Southeast. There was an oversupply of satsuma mandarins in the cold-hardy citrus region last season. That will not be the case in 2025. According to Lindy Savelle, executive director of the Georgia Citrus Association and member of the Georgia Citrus Commission, satsuma supply will be extremely low for the upcoming …
Large Fruit Size Could Be Problem for Cold-Hardy Citrus
Fruit in the cold-hardy citrus region is expected to be in short supply next season due to the trees’ alternate bearing cycle. The fruit also could be too large to sell, creating another concern for growers heading into next season. “Trees with a low crop load tend to have large fruit,” noted Mary Sutton, University of Georgia (UGA) assistant professor …
The Causes of Alternate Bearing
Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist, recently wrote about the causes of alternate bearing in Georgia groves. Alternate bearing is a common problem in many mandarin varieties. A slightly edited version of Sutton’s report follows. CARBOHYDRATES During photosynthesis, leaves produce sugars that are either exported and utilized for growth or stored as starch in …
Optimizing Nitrogen Applications in North Florida
Four University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) horticulture researchers recently wrote an update in the Cold Hardy Citrus Connection about optimizing citrus nitrogen applications in North Florida. The authors are Muhammad A. Shahid, Davie Kadyampakeni, Shahid Iqbal and Muhammad Nadeem. The following edited excerpts explain the research project and provide conclusions: THE RESEARCH The need for …
Alternate Bearing Affecting Cold-Hardy Citrus Production
Trees in the cold-hardy citrus region are expected to produce a low crop in 2025 following a massive crop in 2024. Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist, believes the trees’ alternate bearing cycle will contribute to the decreased crop in 2025, especially for satsuma mandarins. “This alternate bearing pattern probably started in 2023. That …
Management of Mites for Fresh Market Citrus
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Associate Professor Xavier Martini recently wrote an article In the Cold Hardy Citrus Connection about management of mites for fresh market citrus. Martini is an entomologist at the North Florida Research and Education Center. An edited version of his article follows. Two types of mites mainly affect citrus production in …
University of Georgia Honors Jake Price
Jake Price, who has helped introduce cold-hardy citrus to Georgia, was recently honored by the University of Georgia (UGA). He is one of five UGA faculty and staff members recognized for their commitment to public service and outreach. Price won a Walter Barnard Hill Award, named for UGA Chancellor Walter B. Hill. Each award recipient receives a medallion, a permanent …
Nitrogen Reduction Needed in Cold-Hardy Citrus Region
Growers in the cold-hardy citrus region are applying too much nitrogen to their groves. Muhammad Shahid, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), discovered that unfortunate reality while conducting a research project in North Florida. Most citrus growers were following recommendations in the UF/IFAS Florida Citrus Production Guide, which are mostly …
Gene Plays Role in Boosting Citrus Cold Tolerance
A pioneering study has uncovered the role of a key gene, PtrPAT1, in boosting cold tolerance in citrus plants by regulating the accumulation of glycine betaine (GB). This breakthrough deepens understanding of how plants cope with cold stress and opens the door to developing cold-resistant citrus varieties. Citrus plants, traditionally cultivated in tropical and subtropical climates, are highly vulnerable to …
Georgia Citrus Grower Discusses Satsuma Situation
Georgia’s citrus industry has found its footing more than a decade into production. Whether growers can thrive for the next 10 years may depend largely on their ability to expand production beyond satsuma mandarins. “It is a work in progress. Anybody getting into it will need to consider that,” Georgia grower Buck Paulk said. “There’s a lot of unknowns with …
Juice Market Brings Questions for Georgia Citrus Growers
Expansion into the juice market may unlock a profitable marketing opportunity for Georgia citrus growers. But questions remain before growers can start planning this new course of action, says Lindy Savelle, executive director of the Georgia Citrus Association. “Hamlins and perhaps some early-season Valencias would work here in Georgia,” Savelle said. One question Georgia growers have about entering the juice …
Citrus Health Forum Brings Together Growers and Researchers
By Maegan Beatty Earlier this month, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC) hosted the 2025 Citrus Health Forum. Growers gathered to learn about citrus production and hear regional citrus updates. Muhammad Shahid, UF/IFAS assistant professor, presented information on optimizing nitrogen fertilization to enhance the quality of satsuma mandarins. …
Cold-Hardy Growers Eyeing Juice Market
A low volume of fruit in the cold-hardy citrus region is being produced for the juice market. With the current market prices for juiced citrus, that number could increase in the near future. This topic was discussed during the recent Georgia Citrus Association annual meeting in Tifton. “With the prices today, there is a future for it,” said grower Kim …
Why Some Citrus Growers Are Removing Satsuma Trees
Satsuma mandarins are easily produced in the cold-hardy citrus region. But their lack of shelf life is causing multiple growers in the region, which includes North Florida and South Georgia, to pull trees in favor of something else. Those growers includes Lindy Savelle, executive director of the Georgia Citrus Association. She’s removing 400 of 1,000 satsuma trees, or about 40% …
Cold-Hardy Citrus Crop Outlook for 2025
Growers in the cold-hardy citrus region enjoyed a bountiful crop in 2024. Unfortunately, that is not expected to be the case in 2025. Lindy Savelle, executive director of the Georgia Citrus Association, said the expected drop in volume is due to multiple factors, including the winter storm last month that brought historic snowfall and sub-freezing temperatures over multiple days. But …
Protect Trees Post-Freeze With Fungicide
Growers in the cold-hardy citrus region should consider fungicide application following snow last week and multiple days of running irrigation for freeze irrigation. That advice comes from Lindy Savelle, executive director of the Georgia Citrus Association, on the heels of historic snowfall recorded across the Southeast. “I’ve heard some people having up to 10 inches of snow where we grow …
