Before I start, let me be clear: My goal here is not high production, it is using space that would otherwise not produce any fruit.

Does anybody have much experience growing grapes up trees? I have a large maple tree. I am considering running a muscadine (so I don't have to spray) vine up it. I would not maintain it, beyond perhaps some very occasional pruning. Any fruit I would get would be pure bonus, coming from an area that would otherwise produce none.

I know everyone recommends sun for grapes, but in the wild they grow up trees, so I assume that's just for max production. If I'm ok with low yield, is there another reason I should disregard this plan?
