Care
- Light
- Medium to bright indirect light.
- Water
- Water after the upper root zone begins to dry; do not keep saturated.
- Growing medium
- An airy tropical mix with reliable drainage.
- Feeding
- Feed lightly during active growth.
- Temperature
- 65-85 F.
- Humidity
- Average to high humidity with airflow.
- When to consider watering
- Use observed moisture, pot weight, light, and season instead of a fixed weekday.
- Watering method
- Water after the upper root zone begins to dry; do not keep saturated. Wet the root ball evenly and never leave drainage trapped in a cachepot.
- Repotting
- Repot only when roots, drainage, stability, or broken-down medium justify it; increase the pot size modestly.
- Pruning
- Remove damaged growth with clean tools and avoid unnecessary pruning during stress.
- Beginner note
- Treat reminders as prompts to observe. Record what you found, then complete, snooze, pause, or adjust the care item.
Observe the plant and growing medium before acting. A reminder is a prompt to check, not an automatic instruction to water.

Problems to recognize
These links describe possible or look-alike relationships, not a diagnosis. Start with visible evidence and rule out alternatives.
- Excess moisture / root stress: Soft canes and yellow leaves require a root-zone check.
- Bacterial leaf spot syndrome: Wet-looking lesions can spread through splashing and handling.
- Spider mites: Inspect patterned leaf undersides for stippling.
