Light

Bright light with some direct sun. Rotate the pot every few weeks so growth stays even.

Water

When soil is dry; water lightly. Always use a pot with drainage holes and empty the saucer after watering. Plants use far less water in winter.

Humidity and temperature

Humidity: low. 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 extra grit or perlite. Feed lightly in spring and summer with a balanced houseplant fertilizer at half strength; skip feeding in winter.

Our tip

Use a shallow terracotta pot and gritty soil; rot starts at the crown.

Common problems

• Shriveled pearls: Underwatering or root rot; check the roots.
• Mushy pearls: Overwatering.
• Bare top: Too little light at the crown.

Pets

Toxic to cats and dogs (ASPCA), according to the ASPCA plant list. If a pet chews it and shows symptoms, call your vet or the ASPCA Animal Poison Control Center. Check any plant in our Pet-Safe Plant Checker.
