Starting a School Garden Program may seem overwhelming; however, involving parents, neighbors, local nurseries or garden supply stores are a great place to start. It is important to use the resources within your community as community involvement is one of the strongest driving forces behind a successful school garden. In addition, getting support from your school administration from the start of the program is very important. Remember, a school-wide garden program can be very difficult without a system for organizing and operating it. Having a system for organizing it is as important as the soil, water and sunshine will be to your plants. Life Lab has an exhaustive website to help plan, plant, harvest, and create curriculum for school gardens.
