Horticulture is the study and practice of cultivating plants, crops, and trees. It encompasses the fields of science, business, and art, and requires a balance and interaction of these three components for success. Horticulture involves the study of growing a wide range of plants, including crops, herbs, shrubs, trees, fruits, flowers, vegetables, grains, and cereals. It also includes the topics of botany and agriculture, which study the physiology, biology, and chemistry of plants. Genetic engineering and biotechnology are also part of horticulture. Other aspects of horticulture include crop reaping, storage, quality assurance, processing, maintenance, and transportation. The field also focuses on improving crop production, quality, nutritional value, and disease resistance. Additionally, horticulture extends to the study of non-edible ornamental plants. Horticulture employs a variety of tools and technologies, ranging from simple methods like using tractors to more complex techniques involving fertilizers and chemicals. It also emphasizes the responsible use of natural resources. There are two main types of horticulture: amateur horticulture, which is growing plants for personal use, and commercial horticulture, which involves growing plants for profit. Within horticulture, there are different areas of study, including floriculture (the cultivation and sale of flowers), olericulture (the study of vegetables), pomology (the study of fruits), landscape horticulture (the study of landscape plants), and post-harvest physiology (the study of preserving crops after harvesting).
