What is this on my blueberries?

Asked June 5, 2016, 10:20 PM EDT

I have what looks like rust spots on my blueberries. I have a Rubel and a Pink Lemonade. The Rubel has it the worst. Only one small place on the Pink lemonade...I have attached pictures of both plants. What is it and what do I do about it if anything. Thanks for all of your help!!

Might be a couple of things to cause these symptoms. The leaf spots in the first picture could be fungal but it is hard to tell from the image. The other looks nutritional - do you know what soil pH you have? Blueberries need it to be very acid:

Give your local county agent a call as well. I will reassign to them also.


Hi,
Jay's right: it's hard to tell from the image. Can you call or email me directly? We can figure out what our next steps might be.
