Can you plant 10 trees in five rows with four trees in each row?

Planting 10 trees in five rows yields two trees per row. Putting four trees in a row yields two full rows with two remaining trees. An optimal pattern for 10 trees is to place them in two rows of five trees each.

Generally, when planting trees in a row, they should be placed 10 to 15 feet apart. The rows should be separated by 20 to 50 feet. This pattern of planting is effective to create a windbreak at the edge of a field, giving the plants sufficient space so that they are not crowded when they grow larger. Using trees as a snow fence only requires a single row of trees, while screening out high amounts of traffic and noise takes up to six rows of trees to be effective.
