This lovely tree planting bed is so much more than meets the eye! These home owners took great care to protect the existing trees when they graded their new yard.

Remember to keep the root flare exposed when planting a tree or moving dirt around existing trees.  The root flare area takes up oxygen for the tree.

A second thing to be careful about is adding too much weight (with soil or paving) over the root zone.   Most roots grow in the top couple of feet of soil.   They will extend farther than the trees canopy.     A tree takes up the majority of its nutrients from the roots along the drip line (the edge of the canopy).

There is always a risk of damage or loss when changing the grade around existing trees.   But planting beds like these can help lessen that risk.
