San Diego Master Gardeners Association
Mission Statement

Master Gardeners provide research based information on gardening, non-commercial horticulture and pest management to residents of San Diego County. We serve as consultants to more than 260 county schools to advise and assist educators to incorporate gardening and nature into the school curriculum for grades K-12. We maintain an extensive website featuring the 'Plant a Seed, Watch it Grow' web guide, one dozen fully prepared 'Presentations' geared to educating volunteers, activity guides for students and marketing for community support of the garden and, a complete list of Grant Opportunities available for school gardens. The site also includes Quarterly newsletters about school gardens at San Diego County schools and includes links to school specific curriculum materials and projects where available.

The Master Gardener Association of San Diego County School Garden Committee encourages and assists teachers and parent volunteers in starting and maintaining gardens at their respective schools. Today, our membership has over 60 Master Gardeners who will act as school consultants in their geographic residential areas. These MGs work with teachers and parents to advise and assist children with their garden projects.

'Plant a Seed, Watch it Grow' : This guide was developed to help teachers in San Diego County start and maintain a school garden with their students.
It is also meant to help integrate the garden into the curriculum in support of the California State Standards. Although it was written as a guide for teachers, it has information that may be of benefit to parents and their children. Please keep in mind that this guide was written for San Diego County. If you live outside of San Diego County, some of the information may not apply to your location.

Work on the book version started in 1998 when the School Garden Committee began a three year project to research and write what would become the book, Plant A Seed, Watch It Grow. A free copy of the book was sent to every public and private school in San Diego County, over 780 schools, with the cost funded by the Master Gardener Association of San Diego County. Additional copies were sold to individuals, to local community colleges where it has been used as a text book, and to Master Gardener organizations in other California counties.

The web version allowed us to update the guide, add many illustrative photographs, and provide numerous links to other web site resources. We would not have been able to pull the web guide together in the last year without the work done to develop the original book.
