Disease Identification for Dahlias

10 months ago

last modified: 10 months ago

I noticed yellowing leaves at the bottom of my dahlias. Then black areas forming. This all is occurring toward the bottom of my plants, so I'm assuming it's some type of fungus. I'm removing the leaves, but on a couple of dahlias, it's moving inward and upward. Any thoughts on what's ailing my plants and how to treat them?

add the perennial forum if you still can...

your plant is stressed.. and shedding its oldest lowest leaves... were they recently planted.. local drought like MI??.. lawn sprayed???

stressed plants.. and leaves do weird things.. you have to solve the stress.. not the leaf issue...

how about some pix of the whole plants... so we can rule out this isnt entirely normal...

and in every post.. include your big city location... it often matters...

W O W !! What a beauty! Sorry I can't help name it, as I have never seen one like that before. I'll be coming to the UK in September. Do you think one would be able to find dahlia tubers in September? Beautiful dahlia. I'd love to have one like it.

How interesting. The viral diseases look similar to Rose Mosaic Virus. And Smut looks like watering leaves in the heat of the day. I don't think I'll look to closely. Carol
