Light

Bright indirect light; no harsh sun. Rotate the pot every few weeks so growth stays even.

Water

When the top 1 in of soil is dry; more in bloom. 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 medium. Average room temperatures most of the year. To set flower buds in autumn, give it cool nights of about 50-59°F (10-15°C) or 13+ hours of uninterrupted darkness for about six weeks; below 50°F (10°C) can injure it.

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

To set buds, give it cool nights (50-60°F) and long, uninterrupted nights for about six weeks in autumn.

Common problems

• Buds dropping: Moving the plant, drafts or drying out while in bud.
• Limp segments: Root rot from overwatering, or severe drought.
• No flowers: Too much light at night or too warm in autumn.

Pets

Non-toxic to cats and dogs (ASPCA), according to the ASPCA plant list. Check any plant in our Pet-Safe Plant Checker.
