Hardened-off field grown tree
Notice the roots growing through the burlap (arrows). This indicates that the tree has survived the digging process. The survival of this tree is now dependent on the irrigation and handling it receives in the landscape. A tree with roots growing through the burlap in this fashion is said to be hardened-off.
