Dieffenbachia (dumb cane) thrives in bright, indirect light and warm, humid conditions (65-75°F/18-24°C), making it an excellent, low-maintenance houseplant.
Key Care Requirements:
- Light: Prefers bright, indirect light, but tolerates medium to low light conditions. Direct sun can scorch leaves.
-
Water:
Keep the soil consistently moist but not soggy. Allow the top 1–2 inches to dry out before watering again. Drooping leaves often indicate a need for water.
Humidity & Temperature: Thrives in high humidity (60-80%) and warm temperatures (65-75°F). Avoid temperatures below 50°F (10°C) and cold drafts.
Soil: Use a well-draining,, porous potting mix, such as one containing peat, perlite, or coconut coir.
Fertilizer: Feed every 2-4 weeks during the growing season (spring through summer) with a diluted, balanced, liquid fertilizer.
Maintenance: Rotate the pot regularly for even growth. Dust leaves occasionally and prune if the plant becomes too tall or leggy.
Toxicity: The plant contains calcium oxalate crystals; keep away from pets and children, as the sap causes irritation and numbness if ingested.
Common Problems:
- Yellowing Leaves: Often caused by overwatering, poor drainage, or cold drafts.
- Brown/Crispy Tips: Indicates low humidity or underwatering.
- Leggy Growth: A sign of insufficient light
