Ollalieberry Problem





I think this is a disease. What do you guys think? We had a lot of ash on our plants from the Park Fire and then we had rain in August, which we normally don’t.

I appreciate any help in treating this problem. My husband thinks it’s magnesium deficiency and we’ve been giving Epson salt so he thinks the problem is solved, but I’m not so sure.

Check for any bug infestations under the leaves as well?

I’ve never seen them go completely black before… either bacterial disease or herbicide? Not sure myself. Following to see what other people may think. I grow a lot of raspberries and blackberries
