There is healing power in flowers—and in trees, fresh air, and sweet-smelling soil. Just walking through a garden or, for that matter, seeing one out your window, can lower blood pressure, reduce stress, and ease pain. Get out there and start digging, and the benefits multiply. While it may be basic and even old-fashioned, using gardening as a health care tool is blossoming. New or remodeled hospitals and nursing homes increasingly come equipped with healing gardens where patients and staff can get away from barren, indoor surroundings. Many also offer patients a chance to get their hands dirty and their minds engaged in caring for plants.
