About Nepenthes tentaculata

Nepenthes tentaculata · also called Tentacled Pitcher Plant, Borneo Hairy Pitcher · tropical

Nepenthes tentaculata is a compact highland tropical pitcher plant from Borneo and Sulawesi, named for the bristly tentacle-like hairs on its pitcher lids. It traps insects in nectar-baited pitchers. Grow it cool, bright, and constantly humid in a peat-perlite mix, watering only with rain or distilled water to avoid mineral burn.

Preferred mix: Mineral-free carnivorous-plant mix

Watch for — Stalled, soft growth: Usually root rot from soggy, stagnant medium or accidental fertiliser in the soil. Repot into fresh airy carnivorous mix and never feed the roots.
