Growing Tips
Light & Placement
A large species whose vines reach 300 cm, so it needs plenty of space. A greenhouse where humidity can be maintained suits it.
Watering
Keep the medium moist with purified water or rainwater. Maintain humidity at 70% or more.
Temperature & Overwintering
It prefers warm, humid conditions at 22-35°C. As a lowland species, keep it warm through winter without letting temperatures drop.
Soil & Repotting
Use sphagnum moss alone or a similar moisture-retentive material. It grows large, so repot into a generously sized pot.
Pruning & Shaping
Because it grows so large, cut back overgrown vines to keep it compact. Otherwise it is fairly easy to grow.
