“It’s not about how to take care of plants; it’s about how plants can be used to take care of people.” That’s how Tennessee Tech University agriculture professor Douglas Airhart defines horticultural therapy, a medical practice that uses nature, plants and gardening processes as vehicles for providing a wide range of therapy and rehabilitation programs.
“The gardening enthusiast who comes home from a stressful day at work and hoes in his or her vegetable garden for an hour may be reaping positive mental and emotional results from that activity — but that’s not the same thing as horticultural therapy,” Airhart explained. “Horticultural therapy is a clinical process with measurable objectives and outcomes that are closely monitored by a medical team of therapists or rehabilitation professionals,” he said.
Because of his interest and expertise in the field, Airhart is often called on to lead workshops — such as one he led recently at the Memphis Botanic Garden. Clara Ray, a technical horticultural specialist who’s working on a project in Putnam County’s Dry Valley Alternative School, attended the session. “The workshop really helped me put in perspective the specific issues of assessing children with behavioral problems, as opposed to children — and even adults — with mental or physical disabilities, who are the clients for many of the other workshop participants,” she said. “I know plants have had a major impact on my own life, so I will feel good if I can use plants to help just one other person turn their life around.”
In addition to addressing a wide range of client issues, horticultural therapy also draws attention to a wide range of environmental aspects, such as the relaxing response people have to the color green.
“What I like best about it is that — at its core — horticultural therapy has the ability to increase self-esteem and self-confidence on both individual and social levels,” Airhart said. “It can be as simple as taking a cutting from a plant, rooting it in soil, giving it to someone as a gift and seeing them smile, but horticultural therapy teaches people skills they can use to help make themselves and others happy.”
At its greatest expression, horticultural therapy provides a wide range of social and vocational benefits. For instance, a former patient may respond so well to the therapy that horticulture becomes a new source of income for him or her.
The groups who may benefit most from horticultural therapy include:
• People with physical, mental, psychological or developmental disabilities.Someone who’s suffered a traumatic brain injury and needs to work on motor skills, for example, may be encouraged — as a traditional mode of physical therapy — to try squeezing a soft rubber ball a certain number of times per minute. “If a patient loses interest in that activity, a therapist who’s skilled in the practices of horticultural therapy might then hand her a pruning tool and discover that the patient is happy to clip dead leaves from plants until her hands are too tired to prune any longer,” Airhart said.
• People whose age ranges from the youngest of children to the oldest of adults. “A child with a chronic illness who doesn’t want to take his medicine can be given a plant to care for and instructed that the water and fertilizer are the plant’s medicines,” he said. “That way, the child sees first-hand how the plant can thrive with proper care or wilt from neglect.”
• Victims of abuse or the abusers.
• People recovering from illnesses or hospice patients seeking enhanced quality of life in their last days.
• Accomplished or novice gardeners — and even people who’ve never gardened before.
“One of the first horticultural therapy activities I learned was to make a bird feeder from a pine cone smeared with peanut butter and rolled in bird seed,” Airhart said. “That’s an easy, inexpensive activity that can be applicable to patients of all ages who are being treated for a wide variety of conditions.”
