Dieffenbachia prefer soil that is consistently and lightly moist, but not soggy. Generally, aim to water when the top 1”- 2” of the soil is dry, but if the plant is in a lower light condition, it can comfortably dry out a little further.
As a general guide, use a complete fertilizer such as 20-20-20 and feed every 4-6 weeks only during the active growing season. Maintain moderately moist soil. Watering is an important part of growing dieffenbachia. Water thoroughly and then not again until the surface of the potting medium is dry to the touch.
The Dieffenbachia Camille plant and most Dieffenbachia can tolerate low light and even heavy shade. You can place them in areas of the home where there is low light, although they will not grow very fast in these conditions. When watering, water thoroughly and then allow the surface of the soil to dry to the touch.
The Dieffenbachia does well as a houseplant, thriving with year-round average room temperatures of 65° – 75° degrees Fahrenheit. Dieffenbachias will not tolerate low temperatures. Anything below 60° degrees Fahrenheit and growth begins to slow.
Upon purchasing, if the pot is too small, proceed to repot so that the plant may grow adequately. After that, every 2 or 3 years and preferably in spring, repot your dieffenbachia in a pot of a slightly larger size. The roots hate excess water.
