Note this hole is shallow and wide and
is not deeper than the root ball.

Note: This hole is shallow and wide
rather than narrow and too deep.

In this case the hole
is less deep than the root mass and a drainage basin is prepared below the
bottom of the root mass.
Bad Planting Techniques:
The main reason trees would be
planted too deeply is that the planting hole was made too deep by mistake. This
is a particularly common occurrence with holes dug by backhoes because they
frequently are not too accurate. But another problem we have seen is landscape
specifications that are incorrect.

incorrect) Landscape Architect Specifications.

under the root masses. The loosened soil will not be able to support the weight of
the tree and ball, and it will settle to a point where the trunk flare is
width of the prepared holes will make it difficult to back fill them.
This will allow air pockets to remain, which will either stress the new root
growth for water or allow the tree to settle into the space, again making it
too deep in the ground. Click here

moisture and decay to affect normal trunk development and make the tree
likely to become diseased.

look closely, you will notice the trunk flare is shown slightly below soil

Another error is that the burlap has not been removed, but just folded
back and down into the hole. This double or triple layer of burlap will probably
dry out and cause new roots to die when they try to penetrate the layer. If
roots do survive, they will be perforated by the burlap and weakened. Because
these are the roots that will stabilize the tree in the ground, the wound will
make the tree more likely to fail in windstorms.
