Just to let everyone know, Arbor Day in NC is Friday, March 21st! If you join the Arbor Day Foundation its just $10 for six months and they will send you ten free trees (about 8" babies). I know the rain deficit is keeping me from spending too much on plantings but this way the kids can plant some trees for Arbor Day and if they survive everybody wins.
Those trees really are barely rooted cuttings, but it's a great idea to use them for educational purposes with the kids. Maybe set up a rain barrel to water them from, and be sure and plant them where you can keep an eye on them. You could put them pretty close together at first, and then transplant them in a couple of years if they do well.
