By Muhammad A. Shahid and Davie Kadyampakeni Silicon (Si) is getting a lot of attention from citrus growers as a tool to help trees handle stress, especially during cold and freeze conditions. It toughens up plant tissues, strengthens cell walls and helps trees better handle stress when it is applied at the right time. BEFORE FREEZE The most important thing …

Both University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) speakers at a Nov. 28 winter weather workshop warned about the risk of evaporative cooling when using irrigation to protect citrus from freezing temperatures. Microsprinkler irrigation has been the main form of cold protection for Florida citrus for at least the last five decades. The need to understand evaporative …
Multi-county citrus Extension agent Chris Oswalt discussed historical and current freeze protection measures in a virtual Dec. 22 OJ Break. PASSIVE MEASURESSome cold-protection measures are taken well in advance of freezes; Oswalt referred to them as passive measures. They include grove site selection, crop selection and cultural practices. One site selection consideration is planting groves at higher elevations, which are …
By Chris Oswalt and Davie Kadyampakeni In preparation for winter in Florida, citrus growers must first understand some essential concepts related to protecting citrus from freezing temperatures. Specifically, growers need to know when and how to protect citrus trees from freeze damage. WHEN TO PROTECT When (i.e., at what critical temperature) will damage begin to occur? This temperature is dependent on …
By Kelly T. Morgan and Stephen J. Futch Water has been used for cold protection in past freezes with mixed success. Low dew point temperatures and high winds can promote evaporative cooling when insufficient amounts of water are used. Various methods have been used to protect young citrus trees from frost and freeze conditions. Among these, the use of covers …
Florida hasn’t had a widespread tree-killing citrus freeze in years. That’s very fortunate since the industry has been dealing with the highly destructive HLB disease since 2005 and with negative impacts of Hurricane Irma since September. However, a damaging freeze is always a possibility at this time of year. Consequently, multi-county citrus Extension agent Chris Oswalt held a winter weather …
Florida citrus growers hoping to expedite the recovery process for trees impacted by the late January/early February freeze event should pump the brakes and wait — at least until spring. That advice is from Muhammad Shahid, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). He shared tree recovery recommendations with growers during …
Freeze damage to Florida citrus could lead to a buildup in certain diseases. One, in particular, is a major threat, believes Megan Dewdney, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor in plant pathology and Extension specialist. “Our big concern in terms of foliar problems is going to be melanose. Just as a reminder, melanose produces …
Southeast citrus growers hoping that the Feb. 1 freeze would wipe out the Asian citrus psyllid (ACP) population are going to be disappointed. “What we do know about freezes is a lot of time they will reduce or delay the buildup of many of the populations of pests that we worry about,” said Lauren Diepenbrock, University of Florida Institute of …
A South Georgia citrus producer is upbeat after last weekend’s winter storm, which brought plunging temperatures and blistery wind conditions, threatened his grove. Jaime Patrick of Patrick Farms in Omega admitted it would still be a few days before he had a clearer view of the overall impact from the freeze. But he is optimistic. “It’s going to take us …
Cold-hardy citrus producers are now coping with the aftermath of last weekend’s winter storm. Water was a key tool that growers used in efforts to protect their crop from sub-freezing temperatures and blistering wind chills. Now, they need that water to drain as quickly as possible, says Lindy Savelle, executive director of the Georgia Citrus Association. “You don’t want to …
Trees in the cold-hardy citrus region have already experienced severe cold weather in 2026. If forecasts come to fruition this weekend, freezing temperatures will make things worse. Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist, discussed the impact of recent sub-freezing temperatures that citrus in North Florida, South Georgia and South Alabama has been subjected to. …
By Muhammad A. Shahid, KeAndre Leaks and Davie M. Kadyampakeni Right after a freeze, you may notice new growth turning black and leaves hardening, yellowing or looking water-soaked. About a week after a severe freeze, leaves may start to curl and turn brown. Leaves and fruits may begin to drop. Do not attempt any recovery treatments immediately after a freeze. …
Cold-hardy citrus in the Southeast endured sub-freezing temperatures in mid-December, the second major freeze to impact the region this season. Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist, discussed how this freeze impacted citrus trees and fruit in North Florida, South Georgia and South Alabama. “We’re seeing some damage on younger trees that were probably planted …
The second major freeze event of the season occurred this week in the cold-hardy citrus region. It is still too early to gauge the long-term impact of temperatures dropping to the mid-20s in the early morning hours on Monday and Tuesday. However, if growers did not implement freeze-protection measures, this event could be more serious than the first freeze that …
By Davie Kadyampakeni, Chris Oswalt and Muhammad A. Shahid With the onset of cooler temperatures, citrus trees cease active growth and become quiescent. This continued quiescence at lower temperatures results in a subsequent increase in cold hardiness, known as acclimation. Citrus trees proceed through many changes during acclimation, including: The above factors combine to increase the ability of citrus tissues …
Cold-hardy citrus producers need to be prepared for a potential freeze event next week. Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist, cautioned growers on the UGA Citrus Blog that temperatures are expected to drop in the low 30s across the region next Monday and Tuesday, and perhaps in the upper 20s in some areas. The …
