Parkinsonia x desert museum in zone 24
I have a Desert museum cross growing half a mile from the coast in San Diego. It has never flowered and has mildew on its leaves. I have noticed other Desert museum crosses with the same problem growing close to the coast in other neighborhoods. Is there a treatment for this malady or should I replace the tree?
