Kids in Garden

Since 1981, the University of California Master Gardener Program has been extending UC research based information to the gardening public through trained volunteers. The goals of the UC Master Gardener Program in San Bernardino County are: to encourage sustainable landscaping (efficient irrigation, integrated pest management stressing prevention, composting, etc.); to encourage growing food at home and in community and school gardens; and to promote healthy living and healthy communities through outdoor activities.
