Planting your trees and shrubs as windbreaks
Plant windbreaks to the north and west of the area you're planning to shelter. The first row should be planted 100-150 feet away from the house or building to be protected. Follow the general planting directions in Easy Steps to Planting Nursery Stock.
Trees will grow 2-3 times faster if weeds are kept down the first 2 years. Plant the tallest trees in the middle, with shorter trees next to them and bushes on the inside. Use densely needled evergreens for the outside rows. Distance between windbreak rows may vary, but if you plan to use a cultivator for weed control, leave room to maneuver.
