University of Idaho Extension Master Gardeners in Canyon County are committed to helping individuals and communities grow by providing research based information. Our horticulture areas of specialization include sustainable landscapes, home garden vegetable production, youth gardening and volunteer development. With the assistance of the Master Gardener Program Coordinator, our horticulture Extens

ion Educator directs the program. Training for the Canyon County Master Gardener and Advanced Master Gardener is the equivalent of a three credit college class. A Sixteen week 40 hour classroom training teaching about the science of horticulture is followed up by a 40 hour practicum where volunteers apply what they learned in their training by sharing their research based knowledge with their communities. With the help of Master Gardener Volunteers, we provide no-cost horticulture education to thousands of children each year through Junior Master Gardener programs at the Nampa, Caldwell and Middleton public libraries and provide thousands of consumer clientele with research-based gardening expertise and problem solving, free of charge at our Plant Clinics and information booths. If you are interested in becoming an Idaho Master Gardener Volunteer, contact the University of Idaho Extension Office in Canyon County at 208-459-6003.

The 2C Junior Master Gardener volunteers were at last week with Roots and Wings Nature Club! The youth learned what trees need to thrive, planted sweet corn & colorful popcorn, harvested & tasted fresh snap peas, made plant rubbings, and enjoyed the story, "Who Will Plant a Tree". What a fun filled day connecting with nature! ~dlc
