WOODBURY - Volunteers helped clear dead plants, leaves and debris from one of Woodbury's rain gardens Saturday, May 4, in preparation for new plantings.

The rain garden is one of several located at Trinity Presbyterian Church, considered a "green congregation" by the Washington Conservation District. Gardens are positioned to absorb water flowing down the hill toward the church on Tower Drive.

Anna Barker, a University of Minnesota Extension Master Gardener and Ramsey-Washington Metro Watershed District Master Water Steward, said the cleanup was part of a twice-yearly experiment to upkeep the area's rain gardens.

"It's a trial balloon for what maintenance is needed," Barker said.
