Actually most native NC trees do quite well if you dig them up and
transplant them while they are still dormant. I have successfully
done this numerous times and not lost a single plant. All you need to
do is dig them out with a decent sized root ball and plant em quickly
in a good sized hole, and of course water a bit the first summer. You
can also get great trees from cuttings. I've got a bunch of live
oaks, willows, crape myrtles growing in the shade of the back yard
right now from cuttings... there are several web sites with good
information how to do this. I've been surprised at how easy it is with
most trees.
