I bought these two starter Nepenthes Lady Luck plants from an Etsy seller, they arrived last month. I have a house full of thriving plants but as you can see, one of these is quite dead and the other is headed the same way, can anyone tell by the state of the mostly dead plant what can be done to save the other one? I have kept the soil moist - but should I change to a special soil? I bought a little tabletop greenhouse to keep them in and they get plenty of light and humidity. If anyone has any ideas about saving the other plant - please let me know!
