Published source-backed guide. This guide meets Lorekeeper's published source, care-completeness, safety, and identity checks. It is source-backed, not an expert-review claim.
Non-toxic. This is not a guarantee of safety. Avoid eating houseplants and contact a veterinarian or poison service if exposure causes symptoms.
Care
- Light
- Medium to bright indirect light.
- Water
- Keep lightly moist, never waterlogged.
- Growing medium
- A fine, airy mix that holds some moisture.
- Feeding
- Feed weakly during active growth.
- Temperature
- 65–80°F
- Humidity
- High humidity with airflow.
- When to consider watering
- Use the plant, roots, growing medium, pot weight, and recent conditions together. A calendar is a reminder to observe, not an instruction to water automatically.
- Watering method
- Check below the surface. If care is needed, water the full root zone and allow excess water to drain rather than giving repeated small sips.
- Repotting
- Repot when root condition, drainage, or stability shows a need. Increase pot size modestly and avoid burying the crown or stem more deeply than before.
- Pruning
- Remove damaged or fully spent tissue with clean tools. Avoid cutting healthy variegated or developing leaves only to change appearance.
- Beginner note
- Start with stable light and careful observation. Do not create an automatic task until the plant has been observed in its actual home.
Observe the plant and growing medium before acting. A reminder is a prompt to check, not an automatic instruction to water.
