I kept putting off propagating this beast, but I think now is the time to do so. The 50 cm long vine was pulling the pot out of my hanging planter and got stuck to everything. And the pitchers weren’t all that magnificent this year anyway.
So I cut the vine into 3 pieces, each with 4-6 nodes, and wrapped some paper around the base of the cuttings as a sort of reverse diaper to keep them moist. The water I use is reverse osmosis water with 0 ppm dissolved salts. This is what I usually use to water my carnivorous plants. Nepenthes take a long time to grow roots and I don’t expect them to do anything for the next month or so.
