Hedging Under Study for Cold-Hardy Citrus
One of satsuma mandarin’s drawbacks is its alternate bearing tendency. It will produce a heavy crop load one year and a low one the next year. Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist, said tree hedging may provide a solution. She discussed the management technique at the Southeast Georgia Citrus Update in Lyons, Georgia on …
Understanding Crop Load and Alternate Bearing
By Fernando Alferez and Muhammad A. Shahid Citrus trees bloom profusely. It is estimated that a healthy adult tree can produce more than 200,000 flowers every year. This number is much higher than that of fruits the tree can maintain and develop. Normally only between 1% to 5% of flowers set fruit that develops, matures and can ultimately be harvested. …
FFVA Announces Emerging Leader Class 16 Members
The Florida Fruit & Vegetable Association (FFVA) announced the selection of 13 up-and-coming leaders for Class 16 of its Emerging Leader Development Program. The program is an immersive, hands-on experience addressing the critical issues facing Florida agriculture. It helps class members develop the skills needed to lead within FFVA and beyond. Since its inception in 2011, the program — administered …
Tree Water Status May Predict Citrus Cracking
New research suggests that how citrus trees respond to water stress may be more important than simply how much water they receive. The findings could help growers improve irrigation management, reduce fruit cracking and protect yields as weather becomes more variable. An article about the study — “Linking plant water status dynamics to yield and fruit cracking in citrus orchards …
CRAFT Now Accepting Applications
The Citrus Research and Field Trial (CRAFT) Foundation has announced that applications are now open for Traditional New Plantings Cycle Eight and Existing Tree Therapies (ETT) Round Five. TRADITIONAL NEW PLANTINGS This program evaluates grower-selected rootstock and scion combinations under commercial growing conditions. EXISTING TREE THERAPIES This program evaluates therapeutic treatments designed to improve the health and productivity of mature …
Consumer Demand Outlook for Florida Citrus
By Marisa L. Zansler The 2026–27 Florida citrus season is about to begin, making it an appropriate time to assess the outlook and consumer demand for Florida’s orange, grapefruit and specialty citrus production. For much of the past decade, industry conversations about what lies ahead for Florida citrus have, understandably, centered on its production challenges. The grip of citrus greening, …
A Familiar Format Returns to the Florida Citrus Production Guide
By Michael E. Rogers Florida citrus growers continue to adapt to new challenges, regulations and technologies while maintaining the resilience that has defined the industry for generations. Supporting that effort, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research and Extension programs remain focused on delivering practical, science-based solutions that help growers maintain productive and profitable operations. For …
Hormones May Protect Citrus Trees From Heat Stress
As high temperatures become more common in citrus-growing regions, researchers are searching for ways to help trees better tolerate heat. A new study suggests that two naturally occurring plant hormones — abscisic acid (ABA) and brassinosteroids (BR) — may strengthen citrus trees’ defenses against heat stress. The research was published in the journal Horticulturae by Longfei Jin, Yueting Sun, Yanmei …
California Citrus Mutual Names New CEO
California Citrus Mutual (CCM) has selected Tom Danowski as its new CEO effective Sept. 1. Danowski most recently served 13 years as president and CEO of the Oregon Wine Board and Oregon Winegrowers Association.
