I only just noticed today that two of my plumeria trees (they're about 8 feet tall, have brown spots on both sides of the leaves. I'm suspecting a virus...... I removed a number of the affected leaves. Two other trees planted further away aren't affected. I'm assuming there isn't a cure ? I'm reluctant to remove the trees. I can't figure out how they would get these spots. They've always been healthy.
Brown spots on leaves
Would have liked to have seen a picture. Have you been cutting on these plants where do you figure a virus comes in to play here? Lets see a picture and go from there
