I bought a HUGE N. bical 15 yr. old plant last month. She was in a 17" pot with dark green, 2.5 ft. leaves, but no pitchers. I let her sit in this pot for two weeks under a shade cloth lanai in Tampa area of Florida climate. She started showing black spots on the leaves and the leaves became "curly", I increased the amount of watering she was getting and made sure she received less direct afternoon sunlight. The lanai is getting sun from a north-westen angle. I then transplanted her into a 24" deep pot with spagnum moss, perlite, pumice, orchid bark and peat moss. After a week or so, the leaves continued to get curly and more black, so I cut the leaves mostly. Only three leaves remain, but they are curly and have some black edges and spots. It looks like the plant is dying on me.
For anybody that has extensive experience with N. bicalcarata, please give me some advice to save this plant and get it thriving. Thank you.
