Light
Bright indirect light. Rotate the pot every few weeks so growth stays even.
Water
When soil is mostly dry. 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. 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
Do not cut off old flower spurs; they rebloom from the same spot.
Common problems
- No flowers: Needs brighter light and some maturity.
- Shriveled leaves: Underwatering.
- Yellow leaves: Overwatering.
Pets
Non-toxic to cats and dogs (ASPCA), according to the ASPCA plant list. Check any plant in our Pet-Safe Plant Checker.
