Water Droplets on Dieffenbachia: Guttation vs. Overwatering

An office dieffenbachia produces puddles of water on leaves and desk each morning – more than typical tip droplets.

Likely Causes

• Guttation: Normal nighttime pressure releases xylem sap from leaf margins when soil is wet and humidity high. Usually small droplets.
• Overwatering: Excess soil moisture forces more water out. Check if someone is overwatering or spilling.

Action

Allow top quarter of soil to dry before watering. Ensure pot drains well. If puddles are excessive, reduce watering frequency.

Dieffenbachia sap contains calcium oxalate crystals – avoid contact with skin/eyes and keep away from pets.
