Horticulturist | Research & Encyclopedia Articles

A horticulturist practices the scientific or practical aspects of horticulture— growing, producing, utilizing, and studying horticultural crop plants and plant products. Careers in horticulture range from the scientific to the applied.

Careers in horticulture can be found in government (both state and national) agricultural research agencies, public and private universities, small companies, and multinational corporations. Jobs may entail laboratory work, greenhouse crop production and/or management, and field production. Research may involve developing and testing new products or technologies to improve the quality, appearance, handling, storage, or research and development of new plants or plant-derived products. Additional fundamental research is done to gain understanding of plant function, physiology, biochemistry, and genetics at the organismal, cellular, enzymatic, or molecular levels.

Horticulturists interested in teaching find employment at the high school, community school, vocational school, community college, or university levels. Emerging careers in horticulture include the study of plant-people interactions (the effects plants have on people), and horticulture therapy—the use of horticulture and gardening as a means of rehabilitation for those with physical, mental, or emotional limitations or challenges.

The practical or applied horticulturist is trained to utilize or manage plants and to design and maintain landscapes appropriately. Field horticulturists may be involved in the production of fruits and nuts (pomology), grapes (viticulture), and flowers and greenhouse crops (floriculture). They may also handle the arrangement, display, and marketing of cut flowers andgreenery (floristry). Other possible areas of responsibility include the production of ornamental plants, trees, and shrubs (nursery production); landscape design, installation, and management; public or private garden installation and care; the design, installation, and maintenance of plants in indoor environments (interior plantscaping); turfgrass production, installation, and upkeep; and the handling, storage, and shipping of horticulture crops or plant products. The practical field horticulturist handles plant nutrition by fertilization, water status by irrigation, and plant size and shape by pinching, pruning, training, and mowing. Plant growth, development, and flowering is managed by the use of regulating chemicals or environmental management (temperature and light intensity and duration). The horticulturist is often the person primarily responsible for pest (both insects and disease) control and prevention management. Ultimately, the horticulturist is responsible for producing plants or plant products of the highest quality, value, and appearance.

Exciting developments in horticulture include the exploration of new plants as landscape greenery or for their potential medicinal contents and the discovery of wild types of cultivated crop plants such as strawberry, onion, tomato, or apple, which may contain genes for disease resistance or improved nutritional quality. Crops are being bioengineered for improved pest resistance, thereby requiring less pesticide in production, and being modified for increased storage life. Molecular biology and genetic engineering may result in the development of entirely new crops and/or the production of plants containing phyto-pharmaceuticals—plant-produced chemicals for use as beneficial drugs. Molecular biology and biochemistry are shedding new light on how plants grow and function, which will lead to new developments in crop production systems and management.

The level of employment and responsibility of a horticulturist relates to one's amount of training, education, and experience. Horticultural training at the high school and vocational level typically involves work in plant management, production, and maintenance operations. At the college level, horticulturists receive fundamental education in plant science and biology as a foundation to understanding plant growth, development, and management. Typically, college curricula include strong training in science, including botany and plant anatomy/morphology, chemistry and biochemistry, genetics, physics, soil science, pest management, and plant physiology. Additionally, students receive training in the science and technology of horticulture, including greenhouse operations, nursery production, landscape design, landscape installation and management, fruit and vegetable production, and plant propagation. Students interested in pursuing scientific/technology development careers or those who wish to teach horticulture may continue college studies in a master's or Ph.D. program.

Beginning horticulturists are typically responsible for plant management operations. Increased education, training, and experience result in increased decision-making and responsibility for operations and crew management. Entry-level positions with no training or experience begin at minimum wage, but with higher levels of training, experience, and increased ownership of an operation, salaries exceeded $100,000 per year. In 1999, students with a college degree found employment in the range of $25,000 to $40,000 forentry-level management positions. Salaries increase with experience gained through internships, fellowships, special research projects, travel, and part-time employment.

Horticulture production, education, and science careers can be found throughout the world. In the United States, primary horticulture production occurs in California, Florida, Texas, Georgia, Michigan, New York, Ohio, Pennsylvania, and New Jersey. However, landscape horticulture, retail garden center production, florist operations, public and private gardening, park landscape management, and landscaping design, installation, and maintenance operations flourish in all towns, cities, and metropolitan areas. International careers can be found through government and nongovernment agencies such as the Peace Corps, or with large multinational horticultural companies.

A commonality of horticulturists is, simply, that they enjoy working with plants. Horticulturists typically have a strong environmental ethic and enjoy contributing to beautifying and improving the environment and conserving natural resources.
