Hedges can enhance your property and provide so many other benefits. Growing a living fence or hedge can reduce noise from passing traffic, create private outdoor spaces, offer a habitat for birds, and provide natural beauty, shade and a windbreak. When planning hedges and privacy screening, you can create a more formal look by planting trees in a straight line. For a more informal look, plant them in groups. One key to growing a beautiful hedge is spacing the trees at the correct distance. Pay attention to the mature height and spread of the trees. Other factors to consider are hardiness zone, sunlight and soil requirements, maintenance requirements and foliage color.
