What's ailing my Coleus??

CAROL HDebbie ManerGail Salminen


I'm getting this discoloration on the leaves of my red Coleus - only the red. The spots are only on the older leaves. There are no visible signs of ?? on the cuttings I've taken from these plants. I've sprayed the affected plants with a fungicide, with no results. Any ideas??? Forgot to mention, they are in my greenhouse.

    difficult to say without actually seeing or testing. I could be ring spot virus or just watering issues. Are the spots getting larger or getting necrotic(dead or dying tissue) around them?

    @CAROL H It is hard to say without seeing the underside of the leaf as well. What I would suggest is that you take a leaf and seal it in a clear plastic baggie and bring it to a nearby nursery. They should be able to help you with identifying the problem and the treatment. Let us know what the diagnosis is.

    Take a leaf to your Columbia County extension agent. That is their job.

    I'm going to take it into the Columbia Co. extension to see what's going on... That was a good idea!! I'll post the finding, Thanks!!
