In my previous post, I mentioned the sloping weedy area beside the vegetable garden as well as the desire for a flower bed. Here's the solution. First I covered the area with 25 year ground cover cloth (weed barrier), leaving plenty to pull up behind what you see above (That's it behind the steel).
In looking for something for a retaining wall, I found these laser-cut steel sheets (2x6') down in the old studio. When the sheet metal company cuts out multiple items for a certain purpose, these are the leftovers. Nils got them free years ago and we have lots of them in different patterns, the pattern being determined by what it cut from them. I find them intriguing and wonderful.
We simply supported them with rebar driven into the ground a couple feet, pulled the ground cover cloth up behind and back filled with good soil. We then topped it off with a 2x6" with a groove sawn into it which fit along the top of the steel to hold it together.
The back-filled area is about 30'x4' and is now filled with newly planted perennials and underplanted with 300 bulbs which should be glorious in spring.
