My basjoo was poorly protected over the winter and rotted to roughly ground level. I cut it off and it has since put out some growth from the center, but only about two inches. It's basically a telescoping effect that's going on without a true leaf dominating yet. It's been uncovered about three weeks. Is there anything special to do when the pseudostem is cut to ground and it starts growing again? It just seems like the outer leaf remnants are inhibiting the growth of the new leaves.
