Just as good fences make good neighbors, good trees can make good fences. They are attractive and can provide privacy while block both the wind and noise. Best of all, they will never require painting. When trying to decide which tree to plant, consider how tall and dense you need them to be. If you need privacy in a hurry, you may want to plant a quick growing variety. You should also consider the location you plant to plant them since some trees take up more space and require specific soil and light conditions to grow.
