Light details

Medium indirect light

Place it one to two metres from a bright window. Avoid direct midday rays.

Watering details

Water once the top 3-5 cm of soil is dry and empty the saucer afterwards. Yellow leaves mean too much water; drooping means watering was late.

Watering needs change with room temperature, pot size and season, so check the soil rather than following a fixed schedule.

Humidity

Average humidity

Copes with normal indoor humidity; keeping it out of direct AC airflow helps.

Temperature

Ordinary indoor temperatures between 18 and 28°C suit it well.

Avoid direct AC airflow and intense heat behind glass in summer.

Soil

A well-draining indoor potting mix.

Fertilizer

A balanced diluted liquid feed once a month from spring to early autumn; stop in winter.

Repotting

Repot when roots fill the pot or push through the drainage holes, when the plant becomes unstable, or when growth slows. Move up one pot size only.

Pruning

Remove yellow or dried leaves at the base; most of these plants need no regular pruning.

Leaf care

Wipe broad leaves with a damp cloth to remove dust, and avoid leaf-polish products.

Caring for this plant in Riyadh

Easy in AC rooms; wash hands after pruning as the sap irritates skin.
