Plant leaves have spots - sick, or dying?

July 16, 2018 5:27 AM

My plant leaves have spots - both blueberry bushes and either a raspberry or blackberry bush. Any idea what it might be?

I have multiple plants with spotty leaves - there doesn't seem to be anything on the underside of the leaves, however.

Any thoughts on what this might be? I am trying to decide if they are salvageable, or if I should give up now, and start over once I have a house where I can put them in threground.

Those aren't so bad, should be salvageable. I'd treat with a fungicide because they likely have some sort of rust. Maybe a 3-in-1 type product, because the blueberry may have some insect damage too.

How big are the pots? They don't look big enough to let a raspberry flourish. I'd put them in larger pots in the fall, or if you have room you could half bury the pots - that will let them root out and grow better, but still let you move them to another place without too much hassle when the time comes.

Response by poster: The pots are not super big (maybe 16"?) - they really grew this spring. I will be able to put them in the ground this fall!

Pretty sure this is not rust, but it could be a lack of air circulation. Try pointing a low-speed fan in their direction and see if that helps - it will take a month or so to tell.

Looks like something fungal, and also like they may be getting overwatered. I wouldn't think twice about it other than to avoid splashing the leaves when watering. They're going to lose all their leaves in the fall anyway, this is not a reason to trash them.
