Horticulture
Overview
ARC's horticulture department serves professionals, students and members of the community. Horticulture seeks to improve plant culture methods, the sustainability of the environment, enriching economic vitality, and influencing the quality of life of individuals and their communities. Horticulturists have a broad knowledge of ornamental plants, turf grasses, fruit and non-fruit bearing trees, vines, and shrubs. Horticulture is producing the plants, marketing plants and landscape products, designing, installing and maintaining the outdoor and indoor environments where we live, work, and play.
California's horticulture industry is a multi-billion dollar business that provides opportunities at many different levels for qualified individuals. ARC's horticulture program prepares students for self-employment, employment, and self-improvement.
