less redundancy if several are are sterile.
I’m aware of all the common diseases. I noted in a previous post that 2 of the Perdue docs contradict each other in terms of documented resistance. I prefer to reference Cornell’s Database that references multiple publications regarding disease susceptibility, which also highlights some of those contradictions.
I have done significant research and engaged with several other members of the forum regarding their more bulletproof cultivars to narrow down my selections. The Orchard I contacted specializes in apples well adapted to the humid south which should work well for me in the Mid-Atlantic Maryland area. @scottfsmith and @hambone have been very helpful in particular.
I feel like you can only do so much research on disease/pest susceptibility before you just have to pull the trigger and try something, otherwise I get stuck in analysis paralysis. the “sterile” nature of some apples was just something I had never heard of.
