Brown Tips on Dieffenbachia: Light and Water Fixes

Browning on dieffenbachia (dumb cane) is almost always caused by too much sun or too much water.

Immediate Corrections

• Light: Bright indirect light only—no direct sun on leaves.
• Water: Water thoroughly, then wait until the top 2 inches of soil are completely dry before watering again.
• Pot size: Do not repot a new plant for at least a year. If you must repot, use the same size pot or only 2″ larger.

If You Suspect Fungus

Spray leaves (top and bottom) weekly with a diluted Lysol-type spray for a month. Only repot after the plant looks healthy.

Keep the plant in its original pot, correct light and water, and it should recover.
