In recent years, Vancouver has seen an explosive growth in community gardens. From once-empty lots to converted concrete boulevards, patches of green have popped up everywhere, helping to transform grey, urban spaces.

But at two unique gardens, the focus is less about the transformation process and more about healing.

"I feel very happy that I am able to do this," Shurli Chan told CTV News on Friday.

Chan is one of many gardeners taking part in a three-year project that examines how community gardening can support mental health rehabilitation.

The study is now in its final year and uses the roof of the Coast Mental Health Resource Centre on Seymour Street. The other garden is located near Clark Drive.

The project is one of the first in-depth studies that explore how gardening and other leisure activities can act as a lifeline for those with severe mental illness.

"This is a low-tech, low-barrier … strategy to address some of the challenges around mental health issues," explained Melinda Suto, who came up with the idea for the project.

The occupational therapist who has decades of experience said the project teaches participants not only about horticulture, but how to take better care of themselves.

"This provides a little oasis, a little break from the exhaustion of dealing with the struggles every day," Suto said.

For participants like Chan, gardening has also helped nurture her self-worth.

Chan was diagnosed with bipolar I disorder, and can sometimes experience episodes of depression, anxiety, and mania when she's alone. Being at the garden weekly has helped Chan connect with others who care about her.

"It's just a very warm and caring community," Chan said. "What you have is an opportunity for people to come together to care about themselves and each other."

The project is set to wrap up next summer. Suto said she hopes to see the program continue after the study is finished.
