What Is Causes Reddish Brown Leaves On Blueberry Bushes?

Overwatering and root rot can cause reddish-brown spots to appear on the leaves of Blueberries. However, these brown regions are not actually spots, since they are just the consequence of leaf tissue drying up as a result of a lack of water.

A phosphorus deficit may manifest itself in the form of maroon-colored blueberry leaves in the springtime. The reddening of the leaves is caused by an increase in anthocyanin synthesis, which normally begins in the older sections of the plant and progresses downward.

It is because of this first setback that the leaves of young blueberry plants sometimes become brown and burn, as they lose water at a quicker rate than their roots can restore it. Keep the soil wet at all times, but allow for enough drainage — blueberries that sit in soggy soil are susceptible to root rot, which also causes the leaves to become yellow and then brown.
