Dieffenbachia Dripping Water: Guttation and Toxicity

Water droplets on the tips of Dieffenbachia leaves are a natural process called guttation—the plant releases excess moisture through hydathodes when soil is wet and humidity is high. It’s a sign of a healthy, actively growing plant, not a problem.

Important Safety Note

The droplets are poisonous, as is all parts of the plant. Dieffenbachia’s common names—“dumb cane” and “mother-in-law’s tongue”—refer to the temporary vocal cord numbness caused by calcium oxalate crystals in the sap. If you have pets (especially cats) or small children, place the plant well out of reach. Ingestion can cause serious irritation, swelling, and distress.

Care Reminder

• Bright, indirect light.
• Water when top inch of soil is dry.
• Keep away from drafts and cold windows.
