Sorry to hear about the death of your oaks. It's often hard to tell what's going on from a description alone. There are at least 16 different plant diseases that we know of which affect oaks. So we can best assist you, can you please share photos showing both the entire tree and also a close up of any symptoms that you notice? Or you can bring a sample (a good sized branch showing the problems that you notice) to your local Extension office. You can find us here:
