Horticulture is the branch of plant agriculture dealing with garden crops, generally fruits, vegetables, and ornamental plants. The SDSU Extension website has articles and information on many of these topics, and it is searchable by categories and keywords using our advanced search.

In addition to our website, this article lists resources that have been compiled to provide research-based information to help every gardener succeed.
