Is my peach tree still alive ?

[Noelia1983]

I bought some trees a few months ago. The trees lost their leaves. Two died, but one of them is still alive. I made the test and you can see the green color on the trunk.
Is he going to died? What I did wrong? Can I do something to fix it.
My husband is upset with me because I am wasting money...
I love in Zone 6. It's a peach tree, Elberta. The soil is clay.

Thank you

That looks fine Noellia.
Keep it well watered and it should be fine.
