Yearly Lifecycle
Care Essentials
Feed every two weeks with a balanced liquid fertilizer during active growth (spring through autumn). Stop feeding in winter when growth slows.
Watch For
- Spider mites in dry indoor air
- Scale insects on leaf undersides
- Root rot from waterlogged soil
- Leaf tip browning from low humidity
Care Requirements
Light
Bright filtered light, no direct sun
Prefers bright indirect light or dappled shade. Direct afternoon sun can scorch leaves. In temperate climates, a conservatory or bright room is ideal.
Watering
Regular moisture, high humidity
Keep soil consistently moist during the growing season. Mist frequently or use a humidity tray. Reduce watering in winter but never let the rootball dry out completely.
Fertilizing
Biweekly liquid feed in growing season
Feed every two weeks with a balanced liquid fertiliser from spring through autumn. Stop feeding in winter when growth slows. Vigorous grower that benefits from regular nutrition.
Pruning
Remove spent flower stalks and dead canes
Cut spent flower stalks to the base after blooming. Remove dead or damaged canes in spring. Thin congested clumps every few years for vigour and airflow.
