Does anyone have a resource recommendation--I'm looking for a breed compatibility guide? I've tried orangepippen.com but the info there is sporadic at best.

Are you asking about pollen compatible varieties to plant together to insure good fruit set? Look in the e-books and fruit growing sections of the HOS site.

Hey I forgot I'd asked this question, then found it in my own search (;

I'm curious specifically about recommendations for varieties that would go well with the Liberty and Honeycrisp that I have in my yard--I guess something in the order of a pollination chart would be helpful.

Like this? http://www.acnursery.com/apple_pollinizer.pdf

That's an excellent example--any more tips, maybe catering heirloom/home-orchard varieties?
