I am planning the layout of a small orchard (2 apple trees, 1 pear and 2 cherries). I live in Iowa (zone 5) and know the type of trees I want, but am unsure of the kind of rootstock given the space I have.
I have a 30x40 ft space. I originally planned on getting two apples on BUD 118, which are large trees and standard pear and two cherries on gisela 6. I am contemplating on whether I should get a semi-dwarf apple on M7 instead since it will be smaller.
Here is the layout I was considering: Suggestions, Thoughts?
