6 Reasons for Yellowing Leaves on Dumbcane

Confused about what causes a Dieffenbachia plant to turn yellow? Though the dumb cane rarely gets sick, improper care can lead to yellow leaves on Dieffenbachia plants. Let's take a look at six reasons why this happens, and how to help your plant.

{1}. Excess Water. During the growing season, your Dieffenbachia needs to be placed in rich, organic soil. Like every plant, they require a good amount of water. But, over watering can cause the roots to rot. The result is yellow leaves.
{2}. Lack of Sunlight. The leaves of the Dieffenbachia are susceptible to sunburn. This condition is caused by direct sunlight, especially during hot summer days. You can avoid this problem by placing the plant near a south-facing window. You can also use tree ferns, Kentia palms, or philodendrons to shade the Dieffenbachia.

If the leaves on your plant are turning yellow, and it's not due to the location, move the plant closer to the window. That way, you can still get the sunlight you need, but your plant won't get scorched.
