Horticulture is the cultivation and management of crops or a garden. The discipline covers a wide range of topic areas, including nursery management, interiorscaping, soil physics, plant and soil science, and arboriculture. An online certificate program in horticulture is designed for graduate students, industry professionals, or horticulture enthusiasts who want to broaden their base of knowledge or boost their credentials. The benefit of enrolling in an online certificate program is that students can complete their course work at a time that suits them best, which means that their school work doesn't have to get in the way of their other obligations.

Completing an Online Certificate Program in Horticulture

An online horticulture certificate program typically requires the completion of 15 credit hours, or five courses, of academic study. A horticulture program may include courses such as greenhouse and high tunnel food production, vegetable crop management, plant breeding methods, small fruit production, and post-harvest physiology. A greenhouse and high tunnel food production course covers hydroponic production of greenhouse tomatoes, soil production of tomatoes, and cool-season crops in high tunnels. The class also discusses pest management, reduced risk pesticides, climate control, physiological disorders in plants, and organic production.

A typical accredited online horticulture certificate program doesn't have an internship requirement. Instead, students just need to complete five courses to graduate from the program. However, some schools may offer internship opportunities for students who live nearby. Keep in mind that the requirements of a program, or the internship opportunities that are available to students, will vary by college or university.

What Your Online Certificate in Horticulture Can Do for You

An online certificate in horticulture is designed to help students develop their knowledge for personal or professional reasons. An individual with a bachelor's degree who wants to study horticulture may also enroll in a master's degree program in the discipline. The master's degree program provides further study in plant genetics and breeding, propagation, production, management, storage, and marketing. Graduates of master's degree program may qualify to work as soil and plant scientists, while a certificate in horticulture may not provide an individual with the credentials they'll need to qualify for some higher-level positions. However, it can still give them an edge for other positions in the industry.

Soil and plant scientists examine the composition of soil and how it relates to crop growth, investigate the effects of alternative soil treatment practices on crop productivity, and develop conservation and soil management methods that forestry companies and farmers can use. The minimum educational requirement to become a soil and plant scientist is a bachelor's degree, but students interested in working in research need to pursue a graduate degree. Soil and plant scientists earned a median annual salary of $57,340 in May 2010, according to the U.S. Bureau of Labor Statistics (BLS). Employment of soil and plant scientists is expected to increase 12% from 2010 to 2020 because of the need to balance increased crop output with the protection of soil, water, and ecosystems, the BLS reports. However, these projections are no guarantee of salary or employment opportunity, which is determined by location, hiring agency, condition of the economy, and a candidate's credentials.
