Dieffenbachia plants are listed under the Leafy Tropicals section of the Jungle & Loom Plant Care Card. They prefer medium to bright indirect light. They can tolerate low light, however, they will grow slowly. Water when the top 2-4 inches of soil are dry for small plants and 3-5 inches of the soil are dry for large plants. Decrease watering frequency slightly less if the plant is in a low light area.
