Hi, firstly, I apologise for all the questions I am about to ask but they will help you get a better answer and therefore (hopefully) a successful outcome.
How much sunlight does the area get? What part of the country are you in? Is it sheltered? Do you use the drive for the car as shrubs will go out as well as up - how much width are we talking about? How far out from the fence have you excavated? Sometimes a lot of rubbish is found at the base of a wall or fence but further out -18" the soil might be of much greater quality and any plant would have a much better chance of survival.
