I received my first nep a little over two weeks ago. When I received it, the very tip of the leaf on the plant was split. In the two weeks time I've had it, the tip of the leaf has browned. This nep doesn't have very many large leaves and I would like to try to save it because I want it to look bushier. I know with orchids you can cut the browning part off and put cinnamon, a natural fungicide, on the open cut. Is that possible with neps too, or will the entire leaf decay after that? Is there any way I can save the leaf?
