My Father-in-Law has a small walled garden and has recently had a small
wall built around the edges of the garden to create flower beds. The
issue is that the existing plants are now about a foot below the top of
the wall and he does not want to damage the plants by covering them in
Does anyone know how he can protect the root of his existing plants
whilst filling up his new walled beds with topsoil?
Any help would be gratefullly received?
