I think this warning is really worth paying attention to. No matter how resistant to fireblight, etc… the tree is, if your fruit all rots on the tree (as my Goldrush is rotting right now) all you’ve grown is an unproductive tree. Bitter Rot resistance, Black Rot resistance, and White Rot resistance are rarely mentioned in the reviews. This thread is one I’ll be studying carefully as I replace a couple of apples. Novamac is rated susceptible by some. Note that my experience with terrible rots on Goldrush doesn’t match other more experienced growers.
