Damage to weeping cherry Sapling has a hole gouged into it and a few vertical gouges. Is this from a woodpecker or frost? We planted it Sept and live in Kennesaw, Georgia. What treatment should we administer to the trunk?
The damage could be done by animals or birds, but likely is Sun scald.
Most trees can recover from small amounts of bark damage but you need to watch closely for signs of insects or disease.

How can you start a tree from a tree? I'm moving and won't be able to dig and take it because it is too big.
You can take some cuttings from the previous season's growth on the tree and re-grow them into trees. This article explains how:

The article said to level the dirt with the top of the root ball. Then mentioned adding mulch. Should the mulch be above or at the top of the root ball?
The dirt should be level with the root ball. The mulch will be on top of it. Make sure the mulch doesn't press up against the trunk of the tree - leave a space of several inches around it to discourage disease and pests.
I have 2 weeping cherry trees , one is doing good the other the top 1/3 seems to be dying can I cut it down and if I do what do I do with the top can I cover it somehow to encourage grown. I have fertilized it and the limbs are growing out of the 2/3 lower trunk but nothing up top.
Unfortunately it sounds as if the one Weeping Cherry top graft has died. Weeping Cherry Trees are grafted onto the trunk of a different root stock. The growth that you describe is growing from the root stock--not from the Weeping portion of the tree.
If this is a new planting--perhaps you planted it last season--the garden center or greenhouse may offer a replacement.
Here are some articles about care information.

For the last 2 years they only flower at the ends of the branches. I have had them for at least 10 years and this never happened before. What can I do?
It's possible some of your buds could have been damaged by cold. Also excess nitrogen can inhibit flowering. If you fertilize your lawn around the plant, this can lead to excess salts and high nitrogen levels. Avoid fertilizing the lawn around your tree.
You can do a soil test to determine if nitrogen is the issue.
If it is an application of phosphorous, like Bone Meal can help boost flowering.

We have had a weeping cherry tree in our yard for the past five years, and it has done fine. This year it started to bud, but then we had a couple of nights in the high 20's and the buds turned black and it appears to have died. Is there anything we can do to bring it back to life?
If the buds were touched by frost and died off, you will not get flowers.
Give the tree time to recover and it should leaf out.
