A customer has asked me to come up with an idea to make the front of there property more private from the main road. They have a square patch of grass about 5m x 5m rasied 1m from the road by a brick wall. (their house is on a hill) They want to plant a hedge around the perimeter that will bush up quickly (within 2 years) but doesnt need to be cut to regulary! they idealy want it to grow about 5 ft tall and be quite dense. Any ideas welcome!!! ???
