Light:
- Prefers bright, indirect light for optimal growth and vibrant leaf color.
- Can tolerate moderate light but may lose some of its variegation and grow slower in lower light. Avoid direct sunlight, as it can scorch the leaves and cause discoloration.
Watering:
- Water when the top 1–2 inches of soil feel dry to the touch.
- Make sure the pot has good drainage to prevent water from sitting in the bottom, which can lead to root rot. Allow the soil to dry out slightly between waterings, especially during the winter months when the plant is not actively growing.
Humidity:
- Prefers high humidity (60–70%) to maintain its vibrant foliage.
- In drier conditions, mist the plant regularly or place it on a humidity tray. Grouping it with other plants can also help create a more humid microclimate.
Temperature:
- Ideal temperature range: 65–75°F (18–24°C).
- Avoid temperatures below 60°F (15°C), as the plant is sensitive to cold drafts and temperature fluctuations.
Soil:
- Use a well-draining, lightweight potting mix. A general-purpose houseplant mix with added perlite for drainage is ideal.
Fertilizer:
- Feed with a diluted, balanced liquid fertilizer every 4–6 weeks during the growing season (spring and summer).
- Reduce fertilization during the fall and winter months when growth slows.
Pruning:
- Remove yellow or damaged leaves regularly to maintain the plant's tidy appearance.
- Pruning is not typically required, but you can trim the plant to control its size and shape if necessary.
Repotting:
- Repot every 1–2 years or when the plant outgrows its container.
- Choose a pot that is slightly larger than the current one, and refresh the soil with a well-draining mix.
Pests:
- Watch out for pests such as spider mites, aphids, and mealybugs. Inspect the leaves regularly, particularly the undersides. Treat infestations with insecticidal soap or neem oil.
Toxicity:
- Toxic to pets and humans. All parts of the plant contain calcium oxalate crystals, which can cause irritation and swelling if ingested. Keep it out of reach of children and animals.
