I am planting apple trees this year for the first time. I am planting different varieties as I believe I am supposed to. My question in spacing is this - Am I OK to plant these trees in a straight line meaning tree A will be 60' from tree C (with tree B in the middle) or should they be in some more of a circular or triangle type arrangement so that A and C are closer to each other?
Sorry for the dumb rookie question like this.
