What I need to be happy in your home:
Light: Dieffenbachia plants are popular indoor plants largely because they do well in shady conditions, but these plants do appreciate bright light during the winter months. During the growing season, the plant prefers dappled shade or indirect light. The plant will favor the side facing the light, so periodically rotate the plant to keep its growth balanced.
Water: 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, but in the winter, cut back on the water. At the same time, it's important not to overwater a dieffenbachia, which can cause rot problems. Make sure the top of the soil is fully dried out before watering.
Amy's Tip: Dieffenbachia can cause serious side effects if eaten.
