Title: What to do about leaf spot on Vaccinium myrsinites in Clearwater FL?
Answered by: Jimmy Mills

QUESTION:

I have recently planted many Vaccinium myrsinites (shiny blueberry) in my yard. These plants seem to have many dead twig branches without leaves. The remaining leaves have red spots. I visited a native nursery yesterday and noticed that their Vaccinium myrsinites have the same issues. The nursery salesman could not explain the cause. Do you have any suggestions on how I can correct the problem? Or tips for healthier Vaccinium myrsinites? Thanks!

ANSWER:

To Mr. Smarty Plants, its sounds like your blueberries Vaccinium myrsinites (shiny blueberry) may be suffering from leaf spot which is a fungal disease. This site of the Plant Pathology Extension of North Carolina State University has pictures of the symptoms, names of the causative agents, and suggestions for treatment. The Blueberry News, the official Newsletter of the Florida Blueberry Growers Association, also has useful information about this problem.

I would also suggest that you contact the folks at the Pinellas County office of the UF/IFAS Extension for some help closer to home.
