Master Gardeners
Who We Are
Master Gardeners share unbiased, research-based horticultural information with home landscapers and gardeners. Another important function of the organization is to encourage young people to enjoy the pleasures of flower and vegetable growing through the Junior Master Gardener program.

What training is required?
Staff are developing training options for the spring of 2026, which will include a hybrid training option, where participants will study online each week and attend a weekly live webinar session. In past years, the online sessions lasted 1.5 hours and were held for 12 weeks. The training may include videos, a Master Gardener manual, reading materials, and quizzes. Trainees can expect to spend at least 4 hours per week working on the content on their own. This includes reading the chapter, completing the quiz, and viewing all the content provided online. Please email Molly Johnson at msedig@illinois.edu to be notified when registration opens. If you have any questions, please feel free to call 815-632-3611.
Self-paced, fully online training may also be available, which includes 14 weeks of material with online quizzes. Trainees can expect to spend at least 4 hours per week working on the content offline as well. Our online training is a great opportunity for participants who need more flexibility. It is a self-paced program that can be completed at any time. The training includes videos, a manual, reading materials, and quizzes. A strong internet connection is highly recommended.
Local counties may offer a limited number of training fee waivers for those interested in becoming Master Gardener volunteers. Ask your local county for more information if this is needed.
