Info on Free Online Horticulture Courses

There are a handful of organizations and universities offering free online courses and training programs in agriculture, garden planning, landscaping and pest control. Current versions of Web browsers like Microsoft Internet Explorer and Mozilla Firefox are usually needed to access these materials. Students will also need a PDF reader, such as Adobe Reader. Because these courses are offered for self-enrichment purposes, students do not receive university credit for completing them.

ACS Distance Education

ACS Distance Education began as a horticultural correspondence school in Australia. Its online courses are delivered as PDF files and supplement textbook-based learning.

  • Hydroponics was designed as a companion to Commercial Hydroponics by John Mason and consists of two parts. Part one covers hydroponic cropping strategies, such as hanging gardens, tiered beds and trellis systems. In the second part of the class, students learn how to grow more productive crops and prevent plant loss. In addition to readings, the course includes four tests and an optional research project.
  • Landscape Design was originally published in Your Backyard magazine and includes four lessons addressing the basic principles behind garden design, environmental studies and landscape planning.
  • Vegetables and Herbs supplements Growing and Using Vegetables and Herbs by John Mason. It consists of four lessons covering topics in site preparation and small-space gardening. Students also learn how to create a formal herb garden and an herb lawn as well as grow vegetables without chemicals. Optional assignments include reporting on a student-created vegetable garden or designing an edible ornamental garden. Four tests are also included.

Tufts University

Tufts University offers an extended course in agriculture that was originally taught over two semesters. While distance learners do not have access to the same discussions, field trips and labs as on-site students, they can use the course lecture notes and slide presentations to study conservation and its relationship to agricultural food systems.

  • Agriculture Science and Policy I cover topics in soil conservation, air pollution, agroforestry, greenhouse gases and wetlands.
