Dieffenbachia is originally from the tropical rain forests South and Central America such as Brazil, Ecuador and Costa Rica. It is used as a decorative outdoor plant in (sub-) tropical regions of the world and can reach a height of 2 metres in those areas.
In temperate climes, the Dieffenbachia sequine makes a wonderful and popular houseplant.
Temperature: Warm weather is preferred.
Light Preference : Prefers Spots with lots of light but that is sheltered from the hottest midday sunlight – early mornings or evenings are not a problem (in fact it will appreciate it!). Usually somewhere around 3 metres from a window is ideal.
Electrical lighting:It grows well in the light of the rooms
Irrigation of water: Watering your Dieffenbachia weekly will help it to grow well – add some plant food for leafy plants to the water fortnightly. Water 2x a week in the warm summer season but do wait until the compost feels dry to the touch.
Humidity : prefers high humidity (60-70%). Spraying the plant regularly will help – 2 or 3 times a day even!
Toxic : Dieffenbachia belongs to the Araceae family and as all members of this family the Dieffenbachia contains a toxic milky sap. There is however, under normal circumstances nothing to worry about. If you do come into contact with it, it is advisable to rinse your skin with water.
As the plant generally grows towards the light, it is a good idea to give it a quarter turn every month – standing it, pot and all, on a wheeled base makes this easier of course.
