When?

Repot in spring when roots circle the pot or push out of the drainage holes. Take stem cuttings with at least one node in late spring or summer.

Step by step

Place near a bright window but out of harsh midday sun.
Add a moss pole or stake and tie stems loosely to it.
Water deeply when the top 2 in is dry; never leave it sitting in water.
Feed monthly in spring and summer with balanced fertilizer.
Guide aerial roots into the pot or onto the pole rather than cutting them all.
Dust leaves with a damp cloth every few weeks.
Repot every 1–2 years while young, then top-dress older plants.
