It's easy to see from these leaves that something is terribly wrong with my sweet bay. In years past I've had scale. I know what to do about those disgusting little things, but this is something I know nothing about. I have questions. Should I remove all the leaves that look diseased? Is this some contagious disease so that this plant should be isolated from my other plants? I prefer not to use chemicals, but maybe? Worst of all, is this something terrible and terminal so that my bay tree should be exiled and sent outside to an icy death?
It's easy to see from the picture that this plant is in big trouble. Perhaps I let it get too dry or watered it too much.The important thing is what should I do next?
