How much topsoil?
Just having a 1 meter high wall built across the back of my yard and I want to plant a mix of evergreens / bushy foliage stuff. (I know nothing about plants). The area gets good sun on summer afternoons and partial shade the rest of the year.
How deep should the topsoil be ? At the moment it's just three quarter filled with rubble but I'm guessing I'll need to replace some of this hardcore with better quality stuff and topsoil. what should I do next? And any ideas on suitable plants? I like the idea of a mix of variegated leaves lavendar and evergreen
