English Ivy Getting Spots and Turning Brown
I have English Ivy growing on the north side of my house. Many of the leaves are getting brown spots, turning yellow and then brown. My neighbor to the south has the same problem with their ivy. I would like to know if this is an insect, a disease, or the effects of winter in Utah. I would also like to know how to combat the problem. Do I need to prune it way back so that there is only new growth that is not infected?
