Apple advice for Zone 4
We're landscaping a new house in zone 4 (Michigan's Upper Peninsula) and would like to grow some apple trees. I'm looking for apple recommendations (honeycrisp, mcintosh, etc.) and tips for putting in young apple trees. We probably have room in areas of full sun for 3 trees. I've heard you should plant two of one type and one of another. Forgive the simple questions... I'm quite a novice. Thank you.
Good places to order for Michigan?
