Cut off a dead leaf at its base, next to the stem. Use clippers or a sharp knife and take care not to nick living areas of the plant.
Prune a Nepenthes stem at its base when the stem has dead leaves or bare areas. Feel along the stem to where it ends in the pot if it is a large plant or it has crowded stems. Insert the clippers around the stem as close as possible to the plant without cutting other stems, or use a knife to sever the stem. Cut the stem 1 to 2 inches from the growing medium.
Remove dead material regularly and new shoots will help to fill out the plant. Pruning gives your Nepenthes a healthy and lush appearance, free of bare areas.
Cut dead traps off a Nepenthes by clipping them right next to the stem. This keeps the plant from having stumps on the stem. Use sharp clippers.
Prune a mature Nepenthes 30 percent in the spring to encourage new growth. Cut all of its stems back by almost one-third of their length. Support remaining stems on a wire trellis or allow them to hang over the pot.
