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.
