Southern highbush blueberries (SHB) are commercially grown throughout Florida in both deciduous and evergreen systems. This calendar addresses general management requirements on a monthly basis for conventional (nonorganic) systems and should be used in coordination with other UF/IFAS EDIS publications. This new 7-page article, published by the UF/IFAS Horticultural Sciences Department, was written by Douglas A. Phillips, Jeffrey G. Williamson, Philip F. Harmon, Oscar E. Liburd, and Peter J. Dittmar.

Evergreen Production System for Southern Highbush Blueberries in Florida

In central and south-central Florida, many southern highbush blueberries (SHB) are grown in an evergreen system, in which the plants do not go dormant, and are managed to retain their leaves from the previous year through harvest the following spring to support early flowering and fruit set. The evergreen system has also been used under tunnels in north-central Florida. This new 3-page publication of the UF/IFAS Horticultural Sciences Department, written by Douglas A. Phillips, Jeffrey G. Williamson, and Patricio R. Munoz, provides an overview of the evergreen production system for SHB in Florida.

Pruning is an essential part of blueberry production and is used to help establish new plantings; promote postharvest growth of new foliage and fruiting wood; balance vegetative and reproductive growth; reduce disease and certain insect pressure; assist in harvesting efficiency; and promote new cane growth and plant longevity. This new 3-page publication of the UF/IFAS Horticultural Sciences Department is a discussion of pruning practices on southern highbush blueberry in Florida. Written by Douglas A. Phillips and Jeffrey G. Williamson.

Citrus root weevil, Diaprepes abbreviatus (Linnaeus) is a destructive pest on citrus trees. It is now becoming a significant pest on blueberry in central Florida, at times causing major damage to blueberry bushes that are more than two years old. This 3-page fact sheet written by Douglas A. Phillips, Oscar E. Liburd, and Larry W. Duncan and published by the UF/IFAS Entomology and Nematology Department will educate blueberry growers on how to monitor, identify, and control citrus root weevil.

Botryosphaeria Stem Blight on Southern Highbush Blueberry in Florida

'Jewel' SHB

Botryosphaeria stem blight is the most common and damaging fungal vascular disease on southern highbush blueberry in the southern United States, causing stem and cane dieback and reductions in yield. Advanced stages of this disease may cause premature plant death, which results in significant replanting costs for growers. Biotic or abiotic stresses from a variety of sources can make plants more susceptible to infection by stem blight pathogens. This new 5-page publication is intended for Florida blueberry growers to use as a guide in the identification and management of Botryosphaeria stem blight on southern highbush blueberry. Written by Norma C. Flor, Douglas A. Phillips, and Philip F. Harmon and published by the UF/IFAS Plant Pathology Department.

Pollination Best Practices in Southern Highbush Blueberry in Florida

Apis mellifera, the European honey bee.

Southern highbush blueberry is the primary blueberry species grown in Florida. It is dependent upon pollinating insects for adequate pollination and fruit. Some Florida growers have reported cases of low fruit set in recent years, in particular on the cultivars Meadowlark and Emerald, which may have been due in part to poor pollination. This 5-page fact sheet written by Rachel E. Mallinger and Douglas A. Phillips and published by the UF/IFAS Department of Entomology and Nematology will discuss blueberry pollinators, some causes of poor pollination, and current best practices to reduce the possibility of poor pollination of southern highbush blueberry.
