Their lush dark green evergreen foliage is what characterizes them. When spring arrives, a coppery-bronze emerges, followed by tiny blueberries in fall & winter.

When Your Tree Is Diseased, It Will Show the Following 3 Signs:
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.

You must know that Japanese blueberry trees usually shed leaves every 2-3 years but will be replaced with new ones.
