. I have been growing passionflower in my yard as an annual (in Canada) for the last few summers. This past fall I brought it inside cut it back and have it in a large east facing window with a grow light above it which I keep on approx 5 hrs a day. It took off and grew beautifully for a few months but now it has what looks like mold developing on the branches. Can I save this plant with some sort of treatment? Any help would be appreciated
