Pls compare the 2 pictures below of my Strelitzia nicolai. What's wrong with the leaves? How do I rejuvenate it? LEFT PIC — plant when I bought it from store in Guangzhou, China. The leaf edges were unfurled, unfolded, unraveled, arched up, and flat. They open out, stretch out and up, curve up. RIGHT PIC — Now the leaf edges have furled, curled up, folded up, crimped, and scrumpled. And the leaves have discolored and become less green! Plant is still in Guangzhou where I live.
