Question

What is the moral of the poem my own true family

Answer 1

I think you mean "My Own True Family" by Ted Hughes.

The moral is that humans should stop deforestation and save the nature. You can elaborate in the same topic. The child is just opened to the truth behind Man's and nature's relation and how Man badly terrorizes nature. The trees make the child promise that  he will plant two trees wherever he sees one cut down with the threat of rooting him to the ground like a tree. The boy emerges from this experience with "the walk of a human child, but his heart was a tree."
