Withering Morus Rubra

Sob sob, I think I have killed my little cutting with my "SMART" idea.
People have use pertile to root the cutting. Since I am unable to locate the pertile, I used the moss instead as it also holds water. After 1 day, the leaves on the plant withered and the cutting looks dehydrated. Now I place it back into water.
Praying hard it will grow well again.
