Q.How To Prevent Rhubarb Red Spot Fungus From Overwintering.

Zone Chester, VT 5a | Ragsanchance added on October 6, 2020 | Answered

I have been battling Red Spot Fungus on my rhubarb all summer, with a Fungicide. It is better, but not gone. I have NOT composted any of the leaves. Will it come back again next year. (This is the first time in 7 years). What can I do now to prevent it’s return in the Spring?
