Lady Margaret is looking just terrible. Being super busy, I forgot to water it day before yesterday when I noticed it looking a bit wilted. By yesterday morning, the leaves were completely dried out to crispiness. I'm just sick about it. That's how fast it happened. I watered it both yesteday and today, a small amount in order not to shock it yet again.

It had been watered maybe 4-5 days earlier. I had no idea passies went downhill so fast when not watered right when needed. Is this true of all passies? I sure hope its not a goner, and can be saved. What should I do? Defoliate it? Or cut it off down to the roots? Will it come back from the roots? Any help would be so much appreciated.
