Someone in Virginia asked me to send him quince scions. I thought, "Wait, Virginia is a summer rain and humidity area. Quince might get a ton of diseases there." Any opinions on that? I know that Viron and other people in that part of the country on this site might be able to give us some ideas about that.
Thanks,

PDX OR
I opened up a very dusty copy of Sunset Western plant encyclopedia that covers everything east of Colorado state. There's no mention of fire-blight that we should worry about. On the other hand everywhere else in continental US is of great concern to almost impossible.
So this link ranks pears and apples verses 6 fruiting quince clones for fireblight resistance;
https://www.ars.usda.gov/resea.....blications
; and the news does not compare favorably in the quince tree department.
One such person living on the east coast could try and become creative using some of the **pears that are listed as the most resistant. They are easy to find ratings. But it involves lots of talent users back east don't much have. Like establishing a scaffold tree of a very resistant rootstock such as some betulafolia or other species clones are supposed to be. Then if your pear does get blasted it only destroys the branch to the point of attachment to the scaffold branch.
**I purposely omitted taking about grafting quince to pyrus stocks because it is not recommended due to incompatibility
Pyrus betulafolia rootstocks are not producing pear trees with early production. So an asian/japanese pear (syn: nashi pear) must be used. At any rate I had great results at home using nashi pears on betulafolia with early cropping of which in the days of paper pictures is still a favorite of mine. So if anyone gets interested in the idea could request a copy via PM. For the rest it's a 30 inch tall young tree that stands with flowers at 3 times the height of my old cat in the picture. Such a thing is never possible with regular pear. Shinseiki is one self fertile nashi pear as listed highly resistant for fire-blight, but I would still recommend seeking out the best cultivar options for the scaffold rootstock as well.
Back to the point of my double ** on graft incompatibility. It's possible to place pear on quince but the other way is asking for trouble.
...who knows why(?) but that's way off the original topic.
John,
My bad. Normally I would also say Virginia would be OK with quince as they grow apples in Virginia:

However, you are saying that the area the person wants to grow quince is the "Eastern Atlantic peninsula of Chesapeake Bay." If this is the area I am thinking of, it is right by the ocean and the warm Gulf Stream with it's own warm micro-climate. That is a job for the local agriculture extension service to sparse out. Here is one link:
