Baltimore Mayor Stephanie Rawlings-Blake and Baltimore County Executive Jim Smith teamed up to plant trees along Chesley Avenue in Overlea Thursday as part of the Growing Home Campaign to plant more trees.

The city and the county, as well as watershed and community organizations, are cooperating in an effort to expand the region's tree canopy and, therefore, improve water quality in urban areas.

Since Growing Home began in 2006 more than 7,000 grees have been planted. And there are $10 money-off coupons available to homeowners who purchased trees worth $25 or more at particpating retailers.
