Question
Hi! I wonder if you can help me with the following

My nephenthusus alata has produced a little cup but the lid hasn磘 poped off and it has been two months now. I keep it in my bedroom window sil and it gets, at least, 5 hours of sunlight

Answer
The primary reason why this happens is because of large fluctuations in humidity during the time when the pitcher was developing.  This is a normal occurrence with newly acquired Nepenthes or when the seasons change.  It may take several months (6-12) for your plant to fully acclimate to its new environment.  Just make sure the soil is always moist and the plant is getting lots of sunlight.  For more information on growing Nepenthes, read our care sheet on our main website.
