Fuji won't ripen in Z4 but Spartan probably would do fine. I'd consider the Minnesota releases like Honeycrisp and Zestar- both very nice. Spartan might be better in the kitchen though.

There's so many possibilities, even September Fuji might work but Fuji's are difficult to manage- at least on vigorous root stock.

Well, it turns out my macintish seeds sprouted. I know they wont be true to type, but it would be a good pollinator, or host tree for some other branches.

Ive thought of honeycrisp, but im not sure what is available here. I am cramped for space and im thinking of grafting.

SPartan apples are my favorites next to fuji. It would be great to be able to grow them here.

Thanks for the advice
