south facing garden land scaping idea

Are you sure that's the correct size, Kisho? 5 feetwide? could you please confirm - is this a long VERY thin piece of ground? Or is it a border, part of a garden?

Kisho, you could set out your path edging (if you are having one), lay weed suppressant down on the path and over the garden area. Cover the path with e.g. gravel etc. and cover your garden area with bark or similar to a depth of approx. 2 inches. That is your maintainance free garden!
To plant you uncover and cut through the weed suppressant membrane, dig your hole, plant and replace membrane and bark.
Hope this helps
