Different types of fruit trees have different spacing needs-pretending otherwise is literally comparing apples to oranges. However, you likely don't need the space you'd expect to plant a fruit tree. Dwarf fruit trees can be planted 8 to 14 feet from each other, depending upon variety. They have a much smaller spread and can be placed in rows just five feet wide. These smaller varieties of trees are outstanding for gardeners without huge, orchard-sized yards. Standard size fruit trees should be given plenty of space to avoid overcrowding. For bigger trees, aim for at least twenty feet of space between them. Remember, your tree may have heavy requirements for sunlight, in order to reach the top of your landscape's canopy.
