Candelaria Silva reports that Grow Boston Greener will be giving away trees to Bostonians with a place to plant them in May:

... The trees are 6-8' tall and come in containers. GBG asks each new tree steward to fill out a site evaluation form which is a brief survey of the growing conditions specific to your yard area so staff can help match the right tree to the right place. Trees need to be planted within a week of receipt and watered once a week for two full growing seasons (April through October) to establish well and grow into the future. ...
