The time has come to hack down my 3' + tall nepenthes. Now, how much should I cut? My N. sanguinea has like 4 shoots (2 from each stem) so should I cut just above the shoots? And should I cut down both of the stems, or just leave one to continue growing? With my N. bongso x maxima, it has 4 growing points/stems. Should I cut them all, or just the tallest one and how far?
