Hello Disneygram, I still see hope for the plant. I would add more soil, up to the similar level it was in before. Either carefully bury it but keep green part above soil level or add more soil to it to bury the neck but keep green part above soil level. I see a good root and there is green at the center so that tells me the rhizome is still alive. Just have to keep it moist and warm, and use a container with drainage holes. Be very patient, it takes awhile after almost dying and then being disturbed with the repot. New leaves form from the center, so it is really good to see the center part of your plant is green, there is good potential for recovery. It actually looks more promising than the state my plant was in when I tried to help it recover. Water the soil and keep it moist, not the crown of the plant.
My plant suffered outdoors in a shady area, but our heat was intense going triple digit at times, got too dried off for about a month or so in the summer of 2011, but with very careful nurturing, keeping it moist, and in shade, then pulling it indoors during the cold months, it recovered. I am really amazed with this plant's staying power.
This is my plant's recovery photos:
It underwent again another bout of getting too dry, we have to be away on an emergency, but it stayed indoors last August all that time, so some leaves dried out, but resuming watering it recovered once more, much faster recovery this time, I guess being in shade and away from intense heat helped.
In both occasions, I did not apply any fertilizers, it is in a bad shape, so got to make it recover properly first. I have not repotted this plant since 2011, so the soil level is rather low now. I plan to do that in Spring. It made its first bloom stalk in July 2016 since its recovery and so far still holding onto it.
This November 2016:
Good luck, hope your plant recovers!
