Follow the objectives and you'll get to the "rock placing" objective.

As you look for the place to place the rock your controller will start to vibrate. As the vibrations get stronger you will have the opportunity to press Y and place the rock.

I'm not sure how you'd do this if you did not have vibration (broken or disabled), but it does seem the right spot to place it is also a dark spot on the ground.

Once you find the first spot, the other two are pretty easy. Since there are three rocks to place, they are spaced at 120 degrees from each other and about the same distance from the tree.

Note: You usually have a bit of a fight before you place the first rock and after you place the last.
