Even though these trees are still considered saplings, transplantation can be stressful and some shock-types symptoms are to be expected. On the other hand, a sand- gravel soil drains water really quickly, and the most important thing you can do for newly transplanted trees is to give them lots of water. Here is a link that explains how much water new trees should receive:

These trees should be mulched as well. A 6" layer of mulch will help keep the moisture levels even. Make sure that you leave about 4" of space where the trunk meets the ground - no "volcanoes" of mulch!

Provide water to these young trees up until the ground starts to freeze. If we have a light snow cover this year, the mulch will be doubly important.

I hope this is helpful. Please contact AaE again if you have further questions.
