Pananep,
When the basal is first produced, it is sustained with food from the main vine. When it is large enough, it will make its own food. Your basal looks big enough to not to have to fight with the main vine for food. Just keep the plant in bright light as much as possible. That will allow the plant to make enough food for both the vine as well as the basal.


From what I see in your pic, your plant is already a upper vine cutting when it is given to you i.e. with green upper pitchers. So the basal shoot produced will started climbing very soon.

If you want to take cuttings of the vine, they are most likely to produce intermediate to upper pitchers than lower pitchers. The cuttings will not go back to producing only lower pitchers.
