Is there someone who can clue me in as to how to save my almost-dead Anthurium harleyi? The photos show at what point my plant is. I don't want to lose this plant. I cut off all leaves about a month ago and put it into a plastic bag (no dirt, just air and humidity). The leaves were green but shriveld. Either I'm impatient or it's not showing any remorse at dying. I am thinking about planting it into a pot and putting the pot into a plastic bag but I'm not sure of a medium. Is there a 'best' hospital medium in a pot, inside a ziploc for A. harleyi? It's such a tough plant and it took a long, long time to get to this point. I suppose it will take a long long time to come back if it has that much life left. Still, any help would be appreciated! This plant dwindled due to dry weather as opposed to wet weather.

The plant root base is still green and firm. The roots that are left are also firm. To me, it has the appearance of being capable of growth but it's just not putting out anything new. I have to get it into a constant environment and that's what I need to know about. Any ideas please.
