Sorry to hear this Chummer. How a tree is apparently disease resistant in one locale and not another is a mystery but apparently so. Your Franklin trees had such great growth on them and excellent form as well.
Our properties are close enough that I would expect similar results here. This is a good example, we really need a compilation of reviews by forum members on all of these newish trees coming out so that we can avoid planting and growing trees for a year or even a few years only to find out the variety may not Stand up to our area growing conditions.
