We recently moved into our home and inherited some beautiful landscaping. Unfortunatly we are new to it all and are learning. We just noticed some vinery that is covering our fence has started to yellow and leaves are falling off. Their seems to be some sort of polleny/white material on the leaves and branches. I am not sure what type of vine it is to even begin figuring out what is wrong. I am so worried all the leaves are going to fall off and leave us with just branchy twigs on our fence-HELP!
