Dieffenbachia problems can be easily overcome in most situations. The most common problem with growing dumbcane dieffenbachia is too much moisture. Overwatering is a common problem with many houseplants and the dieffenbachia houseplant is no exception. Plant in a well-draining soil and water lightly, keeping the soil consistently moist, but not soggy. Check the soil to make sure it is dry 2.5 cm down before watering the dieffenbachia plant. When growing dieffenbachia, most varieties do best in a filtered light situation, where bright to moderate light shines through a sheer curtain or other filtering window cover. Filtered light is particularly important in the spring and summer, when dieffenbachia is producing new, tender leaves that are subject to sunburn if the light is too bright or shines directly on the plant. Rotate plant regularly to provide adequate light to all sides of the plant and prevent it from reaching toward the light on one side. Some dieffenbachia plants require low filtered light. Fertilize twice a month to encourage growth and a healthy plant. A houseplant food high in nitrogen.
