Planted two Allee Elm trees at the same time...is this stress on one??

Question

One tree grew tall and skinny this year, one grew more full, a little shorter, and the trunk even was larger. The shorter one leans a little and the base of the trunk is starting to lose its bark. It is still very strong at the trunk, but the bark is coming off about the first 6 inches of the tree. Would the weight of the tree(I planted it this spring) and the rapid first year growth cause this tree to stress like this?? I have since staked both trees to stop them leaning.

You can eliminate dutch elm disease.

This elm from eastern Asia is known mostly for its long, narrow leaves and its attractive bark. It tolerates urban conditions, is resistant to Dutch elm disease,
The (bark exfoliates in a puzzle-like pattern exposing light gray, slate gray, gray-green and orangy brown colors.")
Other:
Is Resistant to Disease
Is Resistant to Drought
Is Resistant to Insects

The tree seems to be resistant to almost everything so maybe you need to check the above marking for exfoliating bark.
