Practitioners of horticulture are as diverse as the crops that make up the industry and the discipline. They include a wide array of individuals and groups who farm, landscape, garden, research, advise and enjoy the bounty of horticultural plants for their nourishment, health benefits and aesthetics.
Environmental horticulture provides a range of green career paths including in greenhouse production, wholesale brokers, commercial nurseries, garden centers, florists and landscape design and construction firms. There are also green jobs in private and community gardens, municipal parks and state or national reserves.
In anthropology, horticulture refers to a subsistence strategy characterized by the small-scale, non-industrial cultivation of plants for food.[4] Horticulture involves the use of hand tools such as digging sticks, hoes and carrying baskets.[5] In contrast to horticulture, agriculture is viewed by anthropologists as a more intensive strategy involving the use of plowing, animal traction and complex techniques of irrigation and soil management.[6]
The study and practice of horticulture have been traced back many years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities.[7] Horticulture is divided into several categories which focus on the cultivation and processing of different types of plants and food items for specific purposes. In order to conserve the science of horticulture, multiple organizations worldwide educate, encourage, and promote the advancement of horticulture. Some notable horticulturists include Luca Ghini and Luther Burbank.
The origins of horticulture lie in the transition of human communities from a nomadic lifestyle as hunter-gatherers to sedentary, or semi-sedentary, horticultural communities. In the Pre-Columbian Amazon Rainforest, natives used biochar to enhance soil productivity by smoldering plant waste.[15] European settlers called this soil Terra Preta de Indio.[16] In forest areas, such horticulture was often carried out in swiddens, or "slash and burn" areas.[17] In pre-contact North America, the semi-sedentary horticultural communities of the Eastern Woodlands, who grew maize, squash, and sunflower, contrasted markedly with the nomadic hunter-gatherer communities of the Plains people. Mesoamerican cultures focused on the cultivating of crops on a small scale, such as the "milpa" or maize field, around their dwellings or in specialized plots which were visited occasionally during migrations from one area to the next.[7] In Central America, Maya horticulture involved augmentation of the forest with useful trees such as papaya, avocado, cacao, ceiba and sapodilla. In the cornfields, multiple crops such as beans, squash, pumpkins and chili peppers were grown, and in some cultures, these crops were tended mainly or exclusively by women.[18]
In the United Kingdom, there are two main horticulture societies. The Ancient Society of York Florists is the oldest horticultural society in the world and was founded in 1768; this organization continues to host four horticultural shows annually in York, UK.[21] Additionally, The Royal Horticultural Society, established in 1804, is a charity in United Kingdom that leads on the encouragement and improvement of the science, art, and practice of horticulture in all its branches.[22] The organization shares the knowledge of horticulture through its community, learning programs, and world-class gardens and shows.[citation needed]
The National Junior Horticultural Association (NJHA) was established in 1934 and was the first organization in the world dedicated solely to youth and horticulture. NJHA programs are designed to help young people obtain a basic understanding of horticulture and develop skills in this ever-expanding art and science.[28]
The Global Horticulture Initiative (GlobalHort) fosters partnerships and collective action among different stakeholders in horticulture. This organization has a special focus on horticulture for development (H4D), which involves using horticulture to reduce poverty and improve nutrition worldwide. GlobalHort is organized in a consortium of national and international organizations which collaborate in research, training, and technology-generating activities designed to meet mutually-agreed-upon objectives. GlobalHort is a non-profit organization registered in Belgium.[29]
Plant propagation in horticulture is the process in which the multiplication of a species or cultivar is controlled to fit the desire of the horticulturist. It is primarily used to increase the number of individual plants while preserving wanted genetic and morphological characteristics. Propagation involves both sexual or asexual methods.[30] In sexual propagation seeds are used, while asexual propagation involves the division of plants, separation of tubers, corms, and bulbs and techniques such as cutting, layering, grafting.[31]
Environmental control is involved at all scales of horticulture, although the extensiveness of control varies between hobbyist and commercial horticulture. Basic control involves planting location, sunlight availability, water availability, latitude, and longitude.[33]
Commercial horticulture is required to support a rapidly growing population with demands for its products.[35] Due to global climate change, extremes in temperatures, strength of precipitation events, flood frequency, and drought length and frequency are increasing. Together with other abiotic stressors such salinity, heavy metal toxicity, UV damage, and air pollution stressful environments are created for crop production as evapotranspiration is increased, soils are degraded of their nutrients, and oxygen levels are depleted, resulting in up to a 70% loss in crop yield.
The nature of horticulture has changed as areas become more urban. Our program focuses on landscape management and production of nursery and greenhouse plants, which help meet the aesthetic needs in growing urban environments.
Our program provides students with a comprehensive approach to horticulture, teaching proper plant care, to think strategically and holistically in any environment, and how to be successful and competitive within the industry.
The role of the Horticulture Advisory Board is to advise the Horticulture Program on the latest trends and scientific developments within the horticulture and landscape fields. They also provide strategic guidance and help us reach new students in California and beyond.
Advisory board members are distinguished practitioners across the spectrum of areas within the field who share a strong commitment to furthering the standards of horticulture practices within Southern California.
The certificate curriculum is designed to serve students in Southern California and the Pacific Time Zone (PT). Course curriculum focuses on horticulture practices in Southern California as well. Learn more about our online and remote methods of instruction.
Do you love playing in the dirt and watching your work grow? You'll love taking horticulture classes in our Prairie Gardens Plant Lab and growing produce in our sustainable garden. Green thumb not required. Students learn the full life cycle of plant production; plant seedlings in the Greenhouse and nurture them to adulthood, then sell them to excited customers at our annual plant sale. Plant identification, pest and disease control, and pruning techniques are taught in this hands-on, career-focused program. Learn more about careers in horticulture.
In the Ph.D. program, students focus on one of five areas of emphasis: agroecology, crop improvement/plant breeding, crop production systems, plant physiology, and post-harvest biology/physiology. Research may be conducted within these areas with an applied or basic focus, but in association with a cropping system such as agronomy, environmental horticulture, pomology, vegetable crops, viticulture and weed science.
The M.S. program is designed to focus on a cropping system, such as agronomy, environmental horticulture, pomology, vegetable crops, viticulture and weed science. Within that cropping system, the student can specialize in one of a number of areas, including agroecology, biotechnology, breeding and crop improvement, crop physiology, crop production, floriculture, landscape horticulture, mineral nutrition, modeling, nursery production, pest management, plant growth and development, postharvest physiology, revegetation/restoration, and water relations. Research may be conducted within these areas with an applied or basic focus, but in association with a cropping system.
Horticulturists work to enrich our lives by integrating and applying plant science, environmental science, molecular biology, biotechnology, genetics, physiology, and management. Specifically, horticultural science deals with the development, production, growth, distribution, and use of fruits, vegetables, greenhouse crops, ornamentals, and specialty plant crops (used for flavoring and medicine). Horticultural science is one of the most diverse biological sciences one can study at a university. Not only are the biology and genetics of crop plants interesting, but the application of this knowledge is equally important in a myriad of situations. Undergraduate horticulture majors will obtain specialized training in greenhouse/field management and the production and use of fruits, vegetables, nuts, and herbaceous/woody ornamentals through the bachelor of science degree program.
In addition to obtaining a job with an undergraduate degree in horticulture, the major provides an excellent background for graduate study in the field of plant sciences. Areas of graduate study include plant breeding and plant genetics, horticulture, agronomy, plant pathology, or other related fields such as biology, environmental science, natural resource management, agroecology, and genetics.
Students with either undergraduate or graduate degrees in horticulture have a variety of career opportunities. Recent studies show that there are more jobs in agriculture in the US than there are students graduating with agricultural bachelor of science degrees to fill them. As our world grapples with the need to contribute science-based solutions to feeding 9 billion people by 2050, students trained in the agricultural and horticultural sciences will be called on to contribute.
