Light
Medium to bright indirect light. Rotate the pot every few weeks so growth stays even.
Water
About weekly; let bark dry slightly. Always use a pot with drainage holes and empty the saucer after watering. Plants use far less water in winter.
Humidity and temperature
Humidity: average to high. Most houseplants prefer 60-80°F (16-27°C) and dislike cold drafts and heating vents.
Soil and feeding
Use a well-draining potting mix with bark or perlite for air. Feed lightly in spring and summer with a balanced houseplant fertilizer at half strength; skip feeding in winter.
Our tip
Pot in bark, not soil, and never let roots sit in water.
Common problems
- No reblooming: Needs 2-4 weeks of cooler nights (around 55-65°F) in autumn.
- Wrinkled leaves: Root rot or underwatering; check roots.
- Bud drop: Drafts or sudden changes.
Pets
Non-toxic to cats and dogs (ASPCA), according to the ASPCA plant list. Check any plant in our Pet-Safe Plant Checker.
