Horticulture is the science or art of cultivating fruits, vegetables, flowers, or ornamental plants. Horticulture involves five areas of study. These areas are floriculture (production and marketing of floral crops), landscape horticulture (production, marketing and maintenance of landscape plants), olericulture (production and marketing of vegetables), pomology (production and marketing of fruits), and postharvest physiology that maintains quality and preventing spoilage of horticultural crops.
The Latin words hortus (garden plant) and cultura (culture) together form horticulture, classically defined as the culture or growing of garden plants. Horticulturists work in plant propagation, crop production, plant breeding and genetic engineering, plant biochemistry, plant physiology, and the storage, processing, and transportation of fruits, berries, nuts, vegetables, flowers, trees, shrubs, and turf. They improve crop yield, quality, nutritional value, and resistance to insects, diseases, and environmental stresses.
