Dieffenbachia grows best as a houseplant in bright, indirect light. Being a tropical plant, your dumb cane plant will thrive excellently in high humidity.

Dieffenbachias in their growing season love frequent moisture and don't like to dry out. You need to water your plant at least twice a week. In the cold months, this plant does not demand much water to avoid much watering. Simultaneously, it's necessary not to overwater your plant, which can lead to rot problems. Let the soil completely dry out before watering.
