Horticulture, major branch of agriculture science that focuses on garden crops like fruits, vegetables, flowers, landscape gardening, decorative plants and post harvest technology. Horticulture, as defined in the world of gardening and farming, is the practice of scientifically producing, cultivating, selling, and using high-value, closely tended crops in an environmentally friendly and long-lasting way. Horticulture sets itself apart from agriculture by not dealing with extensive crop farming or raising animals. Instead, horticulture revolves around cultivating various crops on smaller plots, while agriculture centres on growing a single major crop at a time.
