Light
Bright indirect light unless the plant label says otherwise. Stretched stems and pale leaves usually mean more suitable light is needed, while bleached or crispy patches can mean the light is too intense. Increase exposure gradually after a move.
Watering
Check the mix before watering and avoid a fixed calendar. Empty any saucer or cachepot after watering. A pot with a drainage hole is essential, and the correct interval changes with pot size, temperature, light, and season.
Soil and potting
Use loose, well-drained houseplant mix in a pot with a drainage hole. Repot only when the mix has broken down or roots have filled the pot. Move up one pot size so extra mix does not stay wet around the roots.
Humidity, temperature, and feeding
Average household humidity; avoid sudden drafts. Keep the plant away from heating vents, fireplaces, and cold glass. During active growth, feed lightly at the label rate or half strength. Skip feeding when dormant, newly repotted, or stressed.
Pruning and common problems
Let new growth and the condition of the mix guide small adjustments.
- Yellow leaves with wet soil: check drainage and roots before watering or fertilizing again.
- Brown, crispy edges: check dry-down, direct sun, salts, humidity, and drafts.
- Leggy growth: increase suitable light gradually and rotate the pot for even growth.
