Light and form
Lower light may keep the plant alive but can lengthen internodes and reduce variegation. A support encourages larger climbing growth.
Watering
Use pot weight and mix moisture rather than a calendar. Root rot and black leaf margins can follow prolonged wetness.
Pruning and propagation
Cut above a node to shorten sparse vines. Healthy node cuttings can root in water or a suitable medium.
Safety
All parts can irritate the mouth if chewed. Keep out of reach and contact a veterinarian or poison service if exposure causes symptoms.
