Pruning and Repotting Large Nepenthes: Best Practices

A grower with a leggy, vining Nepenthes in a 12-inch pot asked about pruning and the best soil mix.

Pruning

Nepenthes are vines; you can cut back vines to encourage branching from the base or nodes.
Cuttings can be rooted like ivy but are slower.

Standard: 1 part sphagnum peat : 2 parts perlite.
Premium: 1 part peat : 1 part orchid bark : 1 part coconut husk (better aeration).
Never use fertilized or chemically amended products.

Pre-mixed soils are available from specialty vendors (e.g., cobraplant.com, californiacarnivores.com).
