Also, Tyler Arboretum uses raised beds to make a walking garden for
blind people. That way they can walk along the bed and feel and smell
the plants easily. It works well for people in wheel chairs also.

Two of my garden plots are 30 in. high. My "short stuff" is there.
They are 8x8 and are very nice for radishes, lettuce, spinach, etc.
My mantra is: "High beds for short stuff; short beds for tall stuff".
