Maintain consistently moist soil, akin to a damp sponge, but avoid waterlogging. Use distilled, rainwater, or reverse osmosis water as tap water can harm the plant.

Reduce watering slightly in cooler months but never allow the substrate to dry out completely.

Pruning is generally not required for health, but spent or dead pitchers can be trimmed off to improve aesthetics. If the vine becomes too leggy, you can prune it back to encourage bushier growth.

Use sterile cutting tools to prevent disease introduction.

Nepenthes rafflesiana can be propagated by stem cuttings or seeds. Stem cuttings are more common; take a section of healthy stem with at least two nodes and plant it in a well-draining, moist medium.

Seeds require specific conditions and are slower to germinate.

Repot only when the plant outgrows its current container, typically every 2-3 years. Use a well-draining, airy potting mix, such as sphagnum moss, perlite, and coco coir.

Handle the roots gently to avoid damage, as they are sensitive.
