I’m looking at getting a fruit tree. In my area (southeast WI) apples would probably be the most successful.
Is it correct that I need at least 2 otherwise they won’t produce fruit unless they pollinate each other? What about those trees that have different fruits on them, are they any good? I saw ones that have two trees wrapped around each other and then I think some of them graft different tree branches onto one trunk. I don’t think I’ve seen any one with a decent tree that had the multi-fruit, so does that mean they never really grow well?
