Does anyone know what this is? Is it a fungus or some kind of disease? What should I do about it.
We have had a lot of rain. The vines are still growing. These are the bottom leaves, but it seems to be spreading. I got rid of the affected leaves after taking the picture, but I can't continue to do so or there won't be any leaves left and I assume they need the leaves for proper growth.
If anyone can help, I would greatly appreciate it.
