@robert_2007 I’ll email Wes Rice to clarify. EDIT: Warren-346 is type Type 1/protandrous:

@northwoodswis4 according to the many folks in zone 4 WI where native pecans are, they crop and fill their shells. I see absolutely no reason why you cannot grow pecans.
Wes Rice says for an ultra-northern pecan cultivar, he likes ‘Deerstand’. I think you should have one of those included somewhere where pollination types work together. You can buy ‘Deerstand’ from Grimo Nursery in Canada. They send beautiful stock.
