Dieffenbachia is a very popular house plant due to its easy going nature. Plants that receive too little light or too little water will simply not grow as quickly as plants that are given proper care.
This plant prefers bright, indirect sun light for the optimal growth. It will accept lighting conditions up to full shade and continue stunted growth. Full sun will burn the leaves.
For the best results, keep the dumb cane plant's top inch of soil moist at all times. It will tolerate extended periods of watering neglect, but the leaves will begin to shrivel. Watering makes the leaves stiffen. Before moving the plant, allow the soil to dry out. This will give the leaves a more rubbery texture which will better survive the handling process.
