2014/15 Average Packing Charges for Florida Fresh Citrus

Ariel Singerman

A survey of Florida fresh citrus packers was conducted in April 2015 to collect data on their packing charges during the 2014/15 season. A total of sixteen packinghouses participated in the survey, seven from the Interior region and nine from the Indian River region. The average of their responses was computed to obtain the estimates presented in this document.

Citrus Reset Management

Stephen H. Futch

Replacement of dead and diseased trees in Florida citrus groves has always been an important part of citrus production. Today, tree replacement is more important than ever since overhead and production costs are escalating and a full stand of productive trees is essential to maximize production and profits. In more recent times, Huanglongbing (HLB), or citrus greening, has accelerated tree loss rates as well as the ability for growers to bring young citrus trees into production. This revised fact sheet discusses a wide range of techniques for providing young tree care. Many of these should prove useful to Florida citrus growers confronted with the problem of managing resets.
