Rose a Sharon not leafing out

Question

I have several plants in a row. All planted at the same time. 4 are not leafing at all as of mid May?? The branches are not dry and drown indicating the plants are dead.

Answer 1

If the branches still bend but don't snap off, just give them a bit more time.
