A productive garden not only promotes sustainability but is inclusive to as many people as possible.  One way to do this is by building raised beds that are accessible to people who use wheelchairs.

The easiest way to build a wheelchair-accessible raised bed is by stacking boards on top of one another until the desired height is reached. The downside to this design is that there is no indentation into which the wheelchair can fit, so the gardener has a limited reach and may need to twist sideways while s/he works.  There are more advanced designs that do allow for a closer reach, but the building procedure is more complex.

Many thanks to Dowling Community Garden for providing comprehensive raised bed design instructions.
