Frequently asked questions
How often should I water a Dieffenbachia?
In average conditions, water a Dieffenbachia about every 8 days — but always check that the top inch or two of soil is dry first. It needs less in winter and more in bright light or summer heat.
Is the Dieffenbachia toxic to cats and dogs?
Dieffenbachia is toxic to pets if chewed and can cause mouth irritation, drooling or vomiting. Keep it out of reach.
How much light does a Dieffenbachia need?
Dieffenbachia prefers medium indirect light.
Why are my Dieffenbachia leaves turning yellow?
Yellowing usually means overwatering. Let the soil dry more between waterings, ensure the pot drains, and confirm the light matches its medium indirect preference.
