Dieffenbachia brown tips
Brown tips usually reflect repeated stress rather than one emergency. The key is separating dry air and salts from underwatering, wet roots, and pest damage.
For dieffenbachia, adjust the diagnosis around this plant profile: Dieffenbachias show yellow lower leaves, drooping, and soft stems when watering or temperature is off. They also react to cold drafts and low light.

How to confirm it
Look for white crust on the soil or pot rim.
Check whether tips worsen near vents, heaters, or hot glass.
Inspect whether new leaves are forming cleanly while old tips remain brown.
Feel the cane base for softness before adding water.
Check whether lower yellow leaves are old leaves or a spreading pattern.
