Pet Warning
Contains insoluble calcium oxalate crystals. If ingested, it can cause severe mouth and throat irritation, drooling, and digestive distress in pets and humans.
Care Notes
Light
Bright, indirect light keeps the clump full. Lower light can stretch growth. Avoid direct afternoon sun that scorches leaves.
Water
Water when the top 1-2 inches of soil are dry. Use a pot with drainage holes and cut back in winter. Empty the saucer after watering.
Soil
A well-draining aroid mix with peat or coco coir, perlite, and pine bark keeps roots aerated.
Humidity & Temperature
Keep temperatures around 65-85°F. Moderate humidity helps; mist or use a humidifier if your home is very dry.
Common Issues
Yellow or damaged leaves can be trimmed at the base. Soft yellowing often means overwatering. Sparse growth usually means more light.
