Your Dieffenbachia will do best in bright, indirect light. It can also tolerate lower light environments, though growth will slow. Avoid direct sunlight which can burn the leaves.


Water your Dieffenbachia when the soil volume is 50-75% dry. Water thoroughly until it drips out the bottom of the pot and remove excess water that accumulates in the saucer.


The Dieffenbachia does fine in average household humidity. It won’t mind an added boost in humidity during the drier months of winter.


Your Dieffenbachia prefers temperatures between 60-80°F. Avoid cold drafts and sudden temperature changes.


Fertilize your Dieffenbachia once per month during the spring and summer with a general purpose houseplant fertilizer diluted to half-strength. Be sure the soil is damp; never apply fertilizer to dry soil.


Dieffenbachia are considered to be toxic to pets and humans if ingested.
