Barriers and Buffers

Asked April 4, 2016, 3:40 PM EDT

What suggestions do you have for trees that are hearty, grow fast, and give a good barrier to traffic/noise,and give privacy. I prefer a tree that is attractive and less expensive (if that's possible). Any ideas would be appreciated. Thanks.

Some suggestions which meet your criteria are:
Thuja Plicata 'Green Giant' grows to 20-40ft tall and 12-20ft wide.
Cryptomeria japonica/Japanese cedar 'Radicans' grows 30-40ft tall,15-20ft wide.
Ilex/holly 'Nellie Stevens' grows to 15-20ft tall and 5-10ft wide.
Juniperus chinensis 'Spartan' grows to 15-20ft tall and 5-10ft wide.
Some shrubs grow as tall as small trees. Consider Viburnum prunifolium-the Blackhaw viburnum. It is multistemmed and grow to 12-18ft tall.
Consider a mixed screen-clusters of 3-5 either in a single row or in a layered planting. Advantage of staggered plants is that they can be spaced more widely allowing for better air circulation while still achieving a full screen. Good air circulation helps reduce the incidence of disease problems. Even is one species does develop problems so severe it has to be removed, the entire planting will not be sacrificed. Mixed screens can also be more interesting and rewarding throughout the seasons, offering a chance to turn a utilitarian screen into a beautiful part of the entire landscape.
