Dieffenbachia
Dieffenbachia
Dieffenbachia, or Dumb Cane, is a fast-growing tropical with large pointed leaves patterned in cream, yellow, and green. It fills a bright corner quickly when you keep moisture and light steady. Keep it out of reach of pets and kids; the sap is irritating if chewed.

Pet Warning
Contains raphides (calcium oxalate crystals). If ingested, it causes intense burning and swelling of the mouth, tongue, and throat, which can lead to temporary loss of speech. Keep away from cats, dogs, and children.
Care Notes
Light
Place your dieffenbachia in bright, indirect light. Direct sun can scorch the leaves; too little light fades the variegation and stretches the stems.
Water
Water when the top 1–2 inches of soil feel dry. Use a planter with drainage holes and empty the saucer after watering. Cut back in winter when growth slows.
Soil
A well-draining, peat-based potting mix works well. Good drainage is the main defense against root rot.
Humidity & Temperature
Aim for 65–80°F and moderate to higher humidity. Mist the leaves or use a pebble tray if your home is dry, and keep the plant off cold drafts. Wear gloves when pruning; the sap can irritate skin.
Common Issues
Yellow leaves often mean watering is off in either direction. Drooping can signal thirst or a cold draft. If the plant gets tall and bare at the base, prune the top to encourage bushier growth.
