Hello, My husband and I recently purchased a home with 20 beautiful, tall Cypress trees. One of them has a brown spot that seems to be getting bigger and bigger. The others are green on the outside but it you pry the tree open, you will see that it is brown inside. Are our 20 beautiful trees dying? I had asked for an arborist to come see and treat them, but they are so busy in our area that they are not available until two months later (in Nov). By then, the trees might be dead! So worried. I have photos if you need to see them. Thank you so much.
