We planted flowering woodbine this year. Everything appears well - there's new growth and flowers are beginning to appear. I do notice that spme of the leaves are looking a little ratty - many are covered with white, dusty powdery stuff and other leaves are browning and look ready to fall off. It looks like the plant has an infection?? of some sort, and I'm sure I need to spray the leaves with something to kill off whatever's attacking the leaves.
Anyone know what this affliction is and know of a good spray to kill it off?
Thanks,
Bob P.
