This year all the leaves on my nandina dropped and are still not leafed out. Never had this before?

I thought Heavenly Bamboos (Nandina domestica) was always evergreen. The database shows a minimum hardiness zone of 6a so I'd think it would survive winters in your zone unless you had an exceptionally cold winter. You can try scratching a branch to see if there is any green wood; or prune a branch back a little way ... if all you find is brittle wood, than the plant may have expired.

A couple hard Winters here have defoliated my Nandina each time. I have not pruned or did anything but water them in warm spells, and they always refresh their stems and leaves in Spring here.

And interestingly, I see more new plants growing beneath them in bad Winters. I think the seeds need the cold.

I am going to be transplanting the new shoots up in the Fall to expand them I really like Nandina!

Thanks for the info. And I have the same thing happening.... new Nandina all under and around the old ones.
