The study related to the cultivation of ornamental trees and shrubs is called arboriculture. Arboriculture involves the cultivation, care, and maintenance of individual trees, shrubs, and other perennial woody plants primarily for aesthetic and functional purposes. Arboriculturists focus on the health and safety of plants in both natural and urban environments, including parks, gardens, and streetscapes. This branch of horticulture emphasizes practices such as pruning, fertilization, pest control, and disease management to enhance the appearance and longevity of trees and shrubs. Arboriculture is important for landscape design, urban planning, and environmental conservation, as it contributes to the creation of green spaces that improve air quality and provide recreational areas for communities. By managing tree and shrub health, arboriculturists play a key role in preserving the beauty and ecological value of natural and built environments.
