The trees are available through TreePhilly, a program at the Philadelphia Parks and Recreation Department.
"You know, it's part of a multi-pronged strategy for increasing the tree canopy in the city in general," said Erica Smith Fichman, the program manager.
The current tree giveaway is for private property and yards in neighborhoods, but not sidewalks.
"As the city's parks and rec department, we also plant street trees and we plant trees in parks and our natural lands in the forests, but we also wanted to provide a service for people to plant trees on their private property," Smith Fichman said.
The program has been in place for seven years.
"We have people who have gotten trees from us back in 2012 and their trees are huge now," she said.
TreePhilly hopes to increase the tree canopy in every neighborhood in the city by 30 percent.
