Hi,
Hope you are well!
We have a lawn that gradually slopes a little at the end of our garden. Probably about 2 feet over a distance of 10 feet or so. I have seen that you can build a retaining wall with hollow blocks in which you can place soil in and plant flowers so you wouldn't know that there was a wall. So the garden would have a straight lawn and flowers against a fence......you wouldn't know the flowers were in a wall. Does this makes sense and is it fairly easy to do?
