Although a major freeze has not affected the Florida citrus industry since 1989, growers continue to rank cold protection as an important information need. A moderate freeze during 1996 further emphasized the need to document current cold protection and related management practices. A statewide survey conducted in 1996 indicated that the National Weather Service and commercial radio or television were the primary sources of weather information in 1996, but when asked where they would obtain agricultural weather forecasts after 1996, growers indicated they would rely more on commercial radio or television, private meteorologists and the extension service. Grower awareness of the effectiveness of cold protection methods decreased with temperature and with grower production experience. Microsprinklers were the most commonly used method for both cold protection and irrigation. Fifty percent of growers surveyed used computers for grove management, primarily for financial record keeping, with younger growers more likely to use computers than older growers. The percentage of growers with small groves is decreasing while the percentage of growers with large groves is increasing.

Callery pear ( Pyrus calleryana ) was brought to the United States in the early 1900s for grafting onto fruit-producing european pear ( Pyrus communis ) trees to aid in fire blight management efforts ( Culley and Hardiman, 2007 ). Although this
The management of vegetation is an important element of roadside maintenance for safety and aesthetics to produce a healthy roadside environment. Johnson (2000) noted that a healthy roadside environment is one that limits maintenance needs and
requirements. This garden space is accessible to the public, and may be used by a variety of classes for educational purposes. In addition to learning about native plant communities, EMGs in the Native Plants Club learn about greenhouse management and

, humid conditions and an average of >30 inches of rainfall per year. Regional conditions can have a significant effect on crop management practices, tree nutritional status, and orchard soil fertility, all of which affect crop production. As a result, it
Important components of water management for transplant production include water quality, the frequency and volume of water application, and the method of application. Water quality factors of concern are alkalinity, soluble salts including sodium absorption ratio (SAR), and ions at potentially toxic concentrations including boron and fluoride. The available water in individual transplant cells is influence by container size and geometry, medium particle size, medium moisture release characteristics, and wetting agents but is primarily determined by irrigation frequency and the amount of water applied at each irrigation. Irrigation scheduling can be done using several methods but is influenced by the crop stage, the water volume applied, and the frequency of drying desired. Transplants can be watered by hose and breaker, stationary sprinklers, traveling boom sprinklers, fog nozzles, or subirrigation. The outcome of experiments testing effects of transplant size, transplant age and fertilizer rates are all influenced by water management.
