Update: here is a picture of where I was last week. Unfortunately, someone gave me a couple of cotoneasters which I could not refuse, so they are at the bottom of the slope, three on the side you see here, and two more on the other side. Some of the pots are not going to end up precisely in the position shown, but the plants are eventually going to cover a lot of area, so I am planting them pretty far apart. The juniperus probumbens 'nana' supposedly wil get to 10' wide!!!. The j. ?? 'Blue Pacific', mostly on this picture, are going to get 5+ feet wide. Any thoughts on this?
