OMG! whats the deal with all this being about my english skills. Okay! OKay! lol! I will try to consult a dictionary before i post next time.
Coming back to the topic, to divide Dionaea muscipula, A number of key factors should be considered:
1) Dionaea muscipula seem to propogate from their rhizomes as the plant ages. This should mean that a well cultivated plant, shouldn't necessarily require assitance for division, as in the course of time, the plant will put forth a new growth point, initiate growth and split in accordance as the division gets older.
2) It isn't recommended to disturb Dionaea muscipula for the sake of an additional plant by up-rooting it and taking a section. Veteran horticulturalists tend to perform divisions and showcase the process with even younger plants, but more importantly, very healthy plants.
VTFlover, my recommendation would be to let your Dionaea muscipula specimen grow undisturbed for atleast one whole season. Ensure that the plant has acclaimatised to your growth conditions and can strive and germinate in that habitat before considering a manual split.
