Small shrubs usually are added in a fourth row if possible. Their shorter height leads the wind up and over taller trees, instead of providing a single straight wall, and provides bird habitat. Seedlings are about 6 inches tall when planted and need to be watered and protected for about two years before becoming established. Field windbreaks provide protection from the hot dry southerly wind. The goal is to reduce evapo-transpiration and increase crop water use efficiency during the summer and while providing uniform snow distribution across the field in winter.
Livestock require protection from north and west winds.
Producers should choose a location easy to transport hay in inclement weather. This is usually in a valley, but may be above the valley to create a holding area out of a low spot. Plant the windbreak in an L-shape with the angle to the northwest. Plant home windbreaks on the north and west sides of the house. They should be dense and stop at least 150 feet away from the house.
