What is afflicting my Rhubarb? #571629

Asked June 18, 2019, 3:21 PM EDT

I have had extremely healthy rhubarb here in Duluth for the last 30 yrs. It has flourished in a sunny spot. I was gone for a few days and found this on the leaves. Suggestions as to how to treat it? Thanks Julie Seelke

Expert Response

It looks like your rhubarb has a leaf spot. It is more common when it is wet. Clean up any leaves come fall and dispose of them. You can still use the rhubarb. Here is a link to info. https://extension.umn.edu/planting-and-growing-guides/growing-healthy-vegetables
