Pruning is an important management tactic that cold-hardy citrus growers need to implement, especially during the early stages of tree development. Fernando Alferez, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus horticulturist, discussed pruning during the Cold-Hardy Citrus Field Day and Workshop in Quincy on Oct. 1. “Pruning is important because it will give the tree …
University of Georgia (UGA) County Extension Coordinator Jake Price recently reported on the Nov. 19 harvest of fruit from six Owari satsuma trees on X-639 rootstock. The trees were part of a pruning field trial. Price said three pruned trees yielded 380, 527 and 457 pounds of fruit, respectively; three unpruned control trees yielded 569, 596 and 418 pounds, respectively. …
A Brazilian study evaluated the effects of top pruning on orange trees located on the edges of an orchard as part of an HLB management strategy. The pruning was an attempt to attract the HLB-spreading psyllid from external areas to the orchard edges and control it, reducing its dispersion into the orchard. Fundecitrus and Embrapa Cassava and Fruits conducted the …
By Jake Price The University of Georgia Owari satsuma pruning project is going to be very interesting. With extremely heavy fruit loads this year, I feel sure next year will be an “off” year for satsumas. It will be interesting to see what the fruit yields will be on the pruned trees compared to the unpruned trees. The six trees in this …
University of Georgia (UGA) Extension agents Jake Price and Sydni Ingram recently shared information about UGA satsuma pruning and thinning trials. An edited version of their Cold Hardy Citrus Connection article follows: The percentage of cull fruit in satsumas is very high due to the fruit being too soft, too green or too big. Satsumas are very cold hardy, delicious, …
Pruning is an efficient strategy to improve citrus greening disease management in Brazil’s Citrus Belt, but requires appropriate procedures and attention from the grower, Embrapa and Fundecitrus researchers reported recently. Embrapa researcher Eduardo Girardi said an orange tree could produce normally without the need for pruning “if the orange tree has no restrictions on its growth.” Without growth restrictions, Girardi …
Due to major problems with pests and diseases, Brazilian producers have adopted alternative practices, such as dense planting, Fundecitrus’ Citricultor magazine recently reported. These practices reduce costs, increase yield and achieve a faster return on investment. As a result of this trend, new production practices are needed to improve management, including the frequent pruning of trees, which is essential in …
“Don’t prune if you do not know why you are pruning,” University of California Cooperative Extension’s Craig Kallsen cautioned in a June 6 webinar about pruning navel oranges. “It’s a lot of work and thus expensive.” “Generally, pruning of any kind reduces total fruit yield,” the citrus and pistachio farm advisor for Kern County stated. “The goal of pruning is …
Three University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers recently authored an Extension newsletter article about pruning practices for cold-hardy citrus. Authors are Muhmmad A. Shahid, assistant professor of horticulture; Shahid Iqbal, horticultural post-doctoral associate; and Fernando Alferez, assistant professor of horticulture. Highlights from the article follow. Establishment of proper plant structure and canopy through pruning is …
By Mongi Zekri Pruning is an important grove practice that increases sunlight penetration within the tree canopy. Sunlight enhances flowering, fruit quality and color development. Sunlight also allows foliage to dry quickly after a rain shower, which reduces problems of fungal diseases. Pruning trees can improve fruit quality and increase fruit size. However, tree response to pruning depends on scion …
Jake Price with University of Georgia Extension in Lowndes County provided an update on pruning of South Georgia citrus trees in a recent Cold Hardy Citrus Connection newsletter. The newsletter is published by the University of Florida Institute of Food and Agricultural Sciences. His report follows: In February 2021, we pruned the Owari rootstock trial trees to where most limbs …
Planting citrus varieties for fresh market production has increased in popularity. With these potentially high-value crops come concerns about management practices, including pruning. Recently, Fernando Alferez informed growers in a virtual presentation about manual pruning principles. Alferez is a University of Florida Institute of Food and Agricultural Sciences citrus horticulturist at the Southwest Florida Research and Education Center. According to …
By Christopher Vincent and Mark Ritenour Planting fresh citrus varieties has increased in popularity. With these potentially high-value crops come questions about management practices, including pruning. This article discusses pruning practices that can improve the health and productivity of citrus trees. The principles of pruning are the same for any citrus plant. However, quality affects value of fresh fruit even …
By Tripti Vashisth and Troy Gainey Pruning is one of the oldest horticultural practices that changes the form and growth of a tree. The pruning process 1) adjusts tree shape and the ratio of framework to fruit-bearing shell of the canopy, 2) alters the shoot/root ratio and 3) changes the carbohydrate (food storage) status of the tree. Under Florida weather …
By Tripti Vashisth and Troy Gainey In the last 11 years, Florida orange production has declined more than 60 percent. This dramatic reduction in yield is attributable to multiple causes, including loss of citrus acreage in the state, citrus canker and other diseases, but huanglongbing (HLB) is now recognized as the primary reason for declining citrus yields. HLB-affected trees are …
By Muhammad A. Shahid, KeAndre Leaks, Davie Kadyampakeni and Carlos Aucique-Perez Postfreeze citrus tree management requires patience and careful observation rather than immediate intervention. Damage to the vascular system (cambium, xylem and phloem) may take months to fully appear. Trees can initially flush in spring but later decline if internal tissues are too compromised. A reliable assessment of survival should …
For the first time in Brazil, Fundecitrus has identified evidence of partial resistance of the fungus Phyllosticta citricarpa, which causes citrus black spot, to fungicides of the strobilurin group. This finding corroborates warnings issued by growers and technicians during the 2024–25 season regarding failures in controlling the disease in areas of the São Paulo Citrus Belt. SAMPLE STUDY A study …
The Georgia citrus industry now has a better grasp on the extent of damage to the state’s crop following the recent freeze events in February and January. Dieback is present in both younger and older trees, says Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist. “For most of the older, established trees that have gotten some …
Florida experienced one of the most damaging freezes in more than a decade this winter. The February episode of the All In For Citrus podcast addresses the impacts the freeze had on citrus. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, notes that it will take some time …
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 …
