How to Grow

Cultivation

In cooler climates, grow in a warm greenhouse or as houseplant (minimum 10-15ºC) in a draught-free position, in moist but well-drained, peat-free, loam-based potting compost, in bright indirect light with moderate to high humidity; sponge the leaves to keep them free of dust and dirt, and water freely and apply a balanced liquid fertilizer once a month in the growing season, but water sparingly in winter; it can use its aerial roots to climb if given support, for example on a moss-covered pole; in warmer climates, grow outdoors in moderately fertile, humus-rich, moist but well-drained soil in partial shade. See houseplant cultivation and Monstera for further information

Propagation

Propagate by internodal softwood cuttings, by tip cuttings with one leaf attached, or by leaf cuttings, all with bottom heat in a sandy propagating mix in summer; or by air-layering in autumn
