Horticulture Graduate Certificate Careers

A Graduate Certificate in Horticulture will mean you can work as any of the following (subject to other experience and qualification areas):

  • Horticulturalist: You will be responsible for cultivating plants or groups of plants in a garden –whether they are ornamental, crops, or medicinal. You will take daily care of the soil, tackling pests and diseases.
  • Agronomist: On a similar note, this is a science concerned with the uses of crops on a landscape and their study. It covers ornamental landscapes, farms, and the meteorological impacts on these crops.
  • Plant Pathologist: Your main role here is identifying and dealing with a range of plant diseases. You will have an expert understanding of diseases from soil, air, environment, and a range of treatments.
  • Horticulture Consultant: Maybe your expertise or passion is now in advising others on what plants to use for a landscape or other ecological design. Your knowledge of plants and ecosystems is useful.
  • Ornamental Horticulturist: City and building design often utilize plants for functional and aesthetic purposes. Your understanding of the local environment and plant management is useful.
  • Landscape Designer: Rather than dealing with individual plants, you will work as part of a landscape design system – choosing plants and groups of plants to create the desired aesthetic.
  • Horticulture Writer: Horticulture as a science also needs communicators in the professional world, and to consumers. You may write about anything from the science of horticulture to general interest.
  • Pest Management Professional: Plants attract all kinds of pests. For food and resource crops, this can be disastrous. You will identify and take measures to deal with plant pests.
