This was my first lime tree, I have a Satsuma orange tree and a lemon tree. I bought the Thornless Key Lime Tree and then planted it in the ground. I watered it extremely well when planted. But then I left for a business trip and my wife didn't water it at all in the first week. When I got back half of it was brown and the leaves were wrapped up dried to where they crunch and are falling off. So I watered it every day for a week and gave it some hormones to help bring it back to life but after 3 more weeks The tree is completely brown and hardly has any leaves on it maybe 2 dozen.

Is their hope or should I just call it?

Thank you very much.
