The leaves may be falling like mad, but it's not too late to plant another tree. Weekend arborists who show up Saturday morning (Nov. 7) at DeWees Park in North Baltimore can pick up a free seedling, courtesy of a new partnership between the city and Constellation Energy. Red oak, willow oak, redbud and river birch can be had for the asking.

The power company has pledged to kick in $300,000 over the next three years to help increase Baltimore's tree canopy through plantings and tree maintenance in neighborhoods and at schools. TreeBaltimore, as the effort is known, is part of Mayor Sheila Dixon's Cleaner, Greener Baltimore initiative. It aims to double the city's tree canopy within 30 years.

The tree planting/giveaway takes place from 9 a.m. to noon, with a ceremony at the outset celebrating Constellation's partnership. The park is at 5501 Ivanhoe Avenue, 21212.  For more, go here.
