"It's a nice community service and we like the children to get involved in the community," she said. "We are very excited about it and we are having a great time. I think everybody should try it."
She noted it was a good learning opportunity for kids.
"They are going to learn how to dig and plant," she said.
Nicoll and Nick Christ, of Baldwin, were working on another pin oak along with Alex and Zach, who Nicoll said were in fifth grade and kindergarten, respectively.
The boys attend Youth's Benefit Elementary in Fallston and are trying to complete the Patriot Program, Nicoll Christ said.
"I think it's wonderful," she said of the Arbor Day event, adding they thought it would be great to volunteer and her kids like "digging and getting dirty."
A group of teenagers from the Havre de Grace Boys and Girls Club also seemed to like the idea of the project.
Alana Scott, 17, of Havre de Grace, said it was a great experience.
"They are going to be here forever," she pointed out about the trees.
Nick White, 16, of Aberdeen, also understood the bigger mission.
"We are saving the planet here," he said.
Their coordinator, Justin Neville, said the group thought it made sense to spend their morning on the grounds of Edgewood Elementary.
"You can never have too many trees," he said.
