"Plant the Sapling" is an objective in the side quest Tree Hugger in Tiny Tina's Assault on Dragon Keep DLC.
Walkthrough[edit]
Once inside the Lumber Yard you will see a highlighted area to plant the Sapling. Bring it there and interact with it to get in the ground. It now becomes the Treant Sapling. The surrounding Orcs will immediately attack it. You need to keep its health up throughout the assault of orcs. The main ones to worry about are the Warriors.
