I bought 5 potted peach trees. I have an area next to my drive where I was planning on planting. All in a straight row. However, before I started I looked up some websites and they are typically recommending a spacing of 20x20 for orchards. I found one site that said you could go down as much as 10x15. I'm planning on only 1 row and really have room to plant only 10 feet apart. I might get away with it as I only have 1 row and no competing trees real close. Any experience here? Will they be too crowded?
