• Common Name: Dieffenbachia
  • Family: Araceae
  • Facts: Dieffenbachia plants can grow outdoors in tropical climates, but specimens kept as houseplants must be kept indoors during most of the year outside the tropics. Temperatures below about 5C (40F) can kill the plant. The plant needs light but filtered sunlight through a window is usually sufficient. When the plant is brought home from the nursery, it will likely need repotting. The plant needs moderately moist soil. The soil should be fertilized with either regular liquid fertilizing or fertilizer pellets or spikes. Leaves will periodically roll up and fall off to make way for new leaves. Yellowing of the leaves is generally a sign of problematic conditions, such as a nutrient deficiency in the soil. Dieffenbachia responds well to hot temperatures and dry climates.
