I have had a Nepenthese Ventrata for 6 years now. For several years it struggles and didn't grow much. It started vining a few year ago, and a year ago I trimmed off some tiny sucker vines and some dying yellowed ones, and it took off. It has 3 vines, the tallest is 4 feet. I have it propped up on a makeshift trellis made of bamboo skewers bound with twist ties lol! It still only produced a few pitchers (like 4) and 3 are half dried up after a few months.
I live in Minnesota, and though we get humid weather in the summer it gets really nasty so we use the AC a lot. Humidity usually in the 50's. Over the winter it can get down to around 35% though.
I have it planted in a mix of perlite, sphagnum moss, and orchid bark.
First off, short of putting it in its own tank or room what can I do to help it grow more pitchers rather than the tips just shriveling up. Secondly, is it okay to let it vine out like I have? Thirdly, if letting it vine like I have is ok, can I get suggestions on how to manage the vine? Can anyone recommend some sort of trellis, and provide tips on how to train the vine without hurting it? Lastly, post up any other suggestions on plant care that I missed that might help please.
