Plumeria leaf tips burned, leaves spotty, some curling
I moved this plumeria from school & a south facing window to my home about 5 months ago. The only place I have to put it is near my balcony door, which gets afternoon sun. When I moved it, it had whiteflies. I wiped off the leaves occasionally but didn't worry too much about it. It did look like they were making spots on my leaves though, so I tried an insecticide. After that many of the leaves turned yellow & fell off--so I decided that wasn't the best route. I've been spraying the leaves, top & bottom, with soapy water. New leaves though are coming out with burned edges, spots, and the leaves are starting to curl. Should I continue with the soap spray? It looks like I've gotten rid of the flies, but they've come back before, so they need to be treated. Anyway, I guess my question is, are the flies the problem or is something else going on?
