Windbreaking tips

The effective zone of protection for a windbreak can be 30 times the height of the trees. However, the maximum protection occurs within 5 - 7 times the tree height. For example, if the windbreak will be 25 feet tall, it should be placed from 125 to 175 feet from the house.

Characteristics of an effective windbreak

• The windbreak extends to the ground.

• Foliage density on the windward side is optimally 60%.

• Two to three rows of evergreen trees in staggered order should be used. If using deciduous trees, there should be five to six rows.

• The length of a windbreak should be 11.5 times the mature width of the stand of trees.

• The tree heights within the windbreak should be varied.

• Evergreen shrubs and small trees can be planted as a solid wall at least four to five feet away from the north side and provide a windbreak. However, it is better to have dense plantings further away so air movement can occur during the summer.

• If large trees need to be planted, it is best to select trees that have a moderate growth rate rather than fast growing varieties. Moderate growing varieties are sturdier against storm damage and generally more resistant to insects and disease.
