Keep the substrate consistently moist but not waterlogged, using distilled, rainwater, or reverse osmosis water. Allow the top centimeter of soil to dry slightly between waterings during active growth.

Reduce watering slightly in cooler months but never let the plant dry out completely.

Trim away dead or browning leaves and pitchers promptly to prevent fungal issues and maintain a tidy appearance. Use sterile scissors or a sharp knife. Remove any spent flower stalks after flowering.

Pruning is generally minimal for Nepenthes maxima.

Nepenthes maxima can be propagated by stem cuttings or seeds. Stem cuttings, taken from healthy mature plants, should be rooted in a moist, well-draining medium like sphagnum moss or perlite.

Seeds require specific germination conditions and are slower to establish.

Repot every 1-2 years, preferably in spring, when the plant becomes root-bound or the potting medium degrades. Use a loose, well-draining, acidic mix, such as a blend of sphagnum moss, perlite, and orchid bark.

Avoid compacting the soil, which can impede drainage.
