Canopy Keeper care instructions attached to newly planted treebox tree

Looks like DDOT Urban Forestry Administration (UFA) is out planting treebox trees in the neighborhood.  

See this just-planted sweet gum rotundaloba tree planted on the northwest corner of Flagler and V Street NW.

And note the Canopy Keeper sign attached to the wires that are attached to the posts holding up the young tree.

Nice to see explicit instructions provided on caring for the tree.
