Hi, I'm very new to gardening and getting ready to plant a new orchard. I ordered several trees from Stark Bro's that should be here any day. All of the trees that I ordered are dwarfs except one semi-dwarf. This is causing me to question the layout of the orchard. Where should I plant the semi? I don't want it to shade and stunt the dwarfs. Any help/advice would be more than appreciated. Thank you
