Do not be alarmed if you see an odd shade of green sprayed on the ground or trees in Richmond.
Local residents recently spotted two trees and an area covered in a dull green colour at the corner of Gilbert Road and River Parkway.
The material is not toxic, explained city spokesperson Clay Adams.
Rather, it is a way to grow grass in an area that is needed.
The spray contains grass seeds and a binding agent to ensure a large area is covered.
"The binding agent will typically be made from peat moss and/or recycled paper and provides moisture retention for the germinating seeds as well as some erosion control function," said Adams.
A biodegradable water-based dye gives it its odd colour and is only for "esthetic purposes," he added.
"It is an economical, reliable way to establish grass on large-scale sites."
