Horticulture is the industry and science of plant cultivation. Some would say that horticulture is the process of preparing soil for the planting of seeds, tubers, or cuttings.[1] Horticulturists work and conduct research in the disciplines of plant propagation and cultivation, crop production, plant breeding and genetic engineering, plant biochemistry, and plant physiology. The work particularly involves fruits, berries, nuts, vegetables, flowers, trees, shrubs, and turf. Horticulturists work to improve crop yield, quality, nutritional value, and resistance to insects, diseases, and environmental stresses. Horticulture usually refers to gardening on a smaller scale, while agriculture refers to the large-scale cultivation of crops.[2] The word is composite, from two words, horti, meaning grass, originating in the Greek χορτον, meaning the same (grass) and the word culture.

Horticulture has a very long history. The study and science of horticulture dates all the way back to the times of Alexander the Great, and has been going on ever since, with present day horticulturists such as Freeman S. Howlett. [3] The origins of horticulture lie in the transition of human communities from nomadic hunter-gatherers to sedentary or semi-sedentary horticultural communities, cultivating a variety of crops on a small scale around their dwellings or in specialized plots visited occasionally during migrations from one area to the next. (such as the "milpa" or maize field of Mesoamerican cultures).[4] In forest areas such horticulture is often carried out in swiddens ("slash and burn" areas).[5] A characteristic of horticultural communities is that useful trees are often to be found planted around communities or specially retained from the natural ecosystem.
