The Japanese blueberry tree is unique and fabulous. Its scientific name is Elaepcarpus decipiens. As its name suggests, it does produce berries, but curiously, they are inedible to humans.

Understanding Japanese Blueberry Trees

Japanese Blueberry Trees are exotic. And they are also known as Green Emerald Blueberry. They are native to China and Japan, but it is common in the southern United States.

Generally, Japanese blueberry trees measure up to 25 or 35 feet tall. So they are good landscaping candidates since they can also serve as a privacy barrier when planted in a row.

Fungal Diseases

Once your Japanese Blueberry Tree leaves start turning yellow, you can say that something bad is happening to them.  2 factors can be causing it, and they are.

Improper watering: This is one of the most common reasons leaves turn yellow. Generally, it is because of the underwatering. If your tree does not receive the necessary water, it won’t be able to receive the required nutrients.
