When you propagate nepenthes through root cuttings and stem cuttings, how old usually are the plants? Does it matter the age or is overall plant size more important? I ask because I want to be sure ahead of time exactly how I should go about it in a way as to avoid killing the original plant and ensuring that the cuttings have a chance of rooting. I will probably only really do stem cuttings, but in case I feel up to it I would like some advice on root cuttings too. Despite my experience with plants, I have very little experience propagating anything by cuttings. Since I am going to end up trimming vines anyways, might as well not waste potential plants. But I want to do it when the plant is good for it, I don't want to waste my rooting powder if it turns out plant age is a factor.
