Trying to plant a hedge to keep children safe
I have an area outside my front door that is 546 cm by 66 cm that has been concreted over with stones on top to decorate. I want to have hedges there and have today tried digging the area up, but there seems to be no end to the concrete and no sign of earth or anything resembling it. So the only other option is to make a raised bed to plant the hedges in but that might only be 6" deep. Really my question is do I continue digging up the concrete or do I/can I plant hedges in a raised bed that is only 6-8"deep?
