Lake County Master Gardeners
Take Your Love of Gardening to the Next Level
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 connect with communities through 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.
