Dieffenbachia plants appreciate bright light during the winter months. During the growing season, the plant prefers dappled shade or indirect light.
Use a fast-draining, well-aerated potting mix. Make sure their drainage is good to avoid damaging the roots; they should never be left in soggy soil.
During the growing season, Dieffenbachias like regular moisture and do not want to dry out. A large dieffenbachia might need to be watered twice a week. In the winter, cut back on the water.
This plant likes above-average warmth. If the temperature drops below 60 degrees Fahrenheit or if the plant is exposed to cold drafts, it is likely to lose lower leaves and assume a palm-like appearance.
For best results, feed regularly (every 4 to 6 weeks) with a balanced, diluted fertilizer, such as a 20-20-20.
Potting and Repotting
Repot annually for best results—simply lift the plant as a whole, knock away any old soil and dead material from the roots, and replace it in a larger container. Watch out for signs of stress on the plant, like roots poking out from the surface, crowding, or falling leaves, which could signal that the plant needs repotting. After repotting a dieffenbachia, give it some time to adjust to its new setting. Make sure to wear thick gloves, or else you risk hurting yourself by contact with the milky, mildly toxic sap.

Dieffenbachia is a genus of tropical flowering plants in the family Araceae. It is native to the New World Tropics from Mexico and the West Indies south to Argentina. Some species are widely cultivated as ornamental plants, especially as houseplants, and have become naturalized on a few tropical islands.
The Dieffenbachia is a lush and showy plant from the tropics of Mexico, South America, and the West Indies. Often called “Dumb Cane” due to its toxic sap that causes irritation when ingested, this plant is not ideal for a space with small children or curious pets. However, with a small amount of caution it poses no significant threat.
This plant will thrive in a spot that receives bright ambient light, but direct sun will scorch the leaves. In an office space, the Dieffenbachia can adapt to fluorescent lighting, though it may take some time to adjust
