Master Gardeners

The mission of the University of Illinois Extension Master Gardener program is "Helping Others Learn to Grow." Master Gardeners involve people in improving the quality of life by helping them find sound management practices for home and urban natural resources, by creating aesthetically pleasing environments, by promoting well-being through people-plant interactions and horticultural therapy, and by contributing to a safe, abundant food supply through home fruit and vegetable production.

This self-guided course is for Illinois residents and can be taken from the comfort of home on a desktop, laptop, or tablet. The training includes videos, a manual, reading materials, and quizzes. The course can be completed in 14 weeks with four hours of weekly work. A strong internet connection is highly recommended. This course is aimed at exposing participants to in-depth horticulture content through 13 modules including soils and fertilizers, plant diseases, entomology, pest management organic gardening and more. After finishing training, participants have the option to put their newfound gardening knowledge to use by applying to become an Illinois Extension Master Gardener Volunteer.
