This type of container garden must go on soil or grass, so be sure to determine the appropriate location on your property, as plant roots grow into the ground. Pollinator gardens require this type of container, in particular if you are getting a PollinateTO grant. For food gardens you must use a stock tank or a raised bed with a bottom; otherwise you may use either type for other purposes.
The metal raised beds from Conquest Steel (vendor #15144) come in a wide range of sizes and possible shapes. You can visit this site to see the possibilities, but do not try to order from them (we get 10% off through the vendor - ask your OA to make the purchase through SAP).
Install the container (assembly with included hardware requires a screwdriver) on a level surface to ensure stability; bottomless raised beds must be on soil. If they are placed on the grass it is encouraged that the area around the containers is mulched to prevent weed growth and/or the build-up of earth. Pollinator gardens require the ground underneath to be broken up for better drainage.
It is important to keep in mind the location of the closest water source (hose bib) when placing your containers (unless hauling water in buckets is part of your DPA!)
Raised beds require a light soil to avoid compaction, so avoid "triple mix" soil as it is too heavy. Full information on ordering soil.
There are endless opportunities for raised beds to provide benefits to outdoor classrooms. The configuration of the beds can help to separate spaces and create smaller areas within outdoor spaces. Getting students involved in all aspects of the garden including budget planning, site placement, research and design, will provide curriculum connections to Mathematics, Science and Technology, Social Studies and Geography, Heath and Physical Education and the Arts.

Painting your containers will help to create an identity for the school while providing students with a sense of ownership of the gardens. It can also help to identify the class/group using each raised bed.
Specialty outdoor paint can be used to paint the containers. It is best to use a water-based and low VOC paint. Talk to your Head caretaker about acquiring an appropriate paint.
