I believe you Carolyn - (as always)
I clicked on this thread to say exactly what you did. Hntrss, if you get a good ground freezing winter - you shouldn't have anything to worry about from those two diseases next year.
In December of 1983, we /DFW Texas area had 295 consecutive hours with temperatures below freezing from the morning of the 18th until the afternoon of the 30th. I have never seen anything close to it freezing here that long before or after December of 83.
