Gardening promotes health. 
Accessible gardening allows gardeners to be outside in the fresh air, expend energy and achieve a sense of accomplishment. Coping with an illness or a disability can be intensely stressful and adaptable gardens allow for a much needed stress relief.
Gardening is empowering, helps to develop range of motion, promote hand-eye coordination and increases strength and balance.
Persons who are challenged with a disability or suffering from other physical limitations benefit considerably from the therapeutic nature of gardening.
