The University of Illinois Extension Master Gardener Program is a volunteer program open to anyone with the desire to learn and to share information with others about research-based landscape and gardening practices.

Master Gardeners reach into the communities with a variety of projects in partnership with local organizations, and they also staff the Master Gardener Help Desk by assisting residents with garden and landscape questions.

Volunteers participate in extensive training sessions conducted by University of Illinois Extension specialists and educators in horticulture, insects, diseases, grasses, woody and herbaceous ornamentals, and fruits and vegetables. The Master Gardener program provides 60 hours of horticultural training in return for 60 hours of volunteer time. Half of the first 60 volunteer hours must be completed at the Master Gardener Help Desk, which is open to the public during the growing season (see details below).
