I want to plant a fast growing, hardy shrub/hedge about 3-4 feet from a heavily-used dirt road. My house, sited at an angle to the road, will be between 5 and 10 feet from the hedge. Depending on the season, sand or mud will be thrown up at the hedge and, in the winter, snow will be plowed up in front of it. The location is mostly sunny. The main purpose of the hedge is to protect the house. Any suggestions?
