At the New England CP show i was talking to Thomas of Dangerous Plants, and he said he has great luck getting basal rosettes to form on amps by letting them dry out just to the point the leaves start to wilt on the edge. Says it has worked every time for him, and he is just trying to get up his courage to try it on his red amp.
So, even if your basal rosette grows, you know how to trigger a new one to form.
I'm excited to finally have an amp of my own (thanks again, WildBill), considering it was the first nepenthes i remember seeing (in a National Geographic decades ago), and very nearly the first CP, at that. It is a cutting, and has developed the first new pitcher. I'm curious what kind of lighting you all give your amps. Is a single fluorescent tube a few inches away enough, or does it need more? I've heard both ways - that they like low light, and that they like a lot of light. I want basal rosettes!!!!
Second question: how extensive (and deep) is the root system? I noticed while repotting my N. alata and by observation of some N. gracilis that the first has a very limited root system, while the second has a very extensive one. Does it tend to be lowlands that have more roots?
Sorry to take the thread off topic....
