I'm looking for ideas on how to figure this area out. I want to raise the right side of the garden bed so its level with the concrete slab on the top right corner of the photo. Where I have placed bricks, I want to either have bricks (I don't have many on hand, however & budget conscious), or sleepers to create a wall. The other issue is the sleeper that is at the bottom of the concrete under the fence - I assume it was left there accidentally after the concrete & fence were installed (was like this when we bought the house). Without removing possibly the entire garden soil, what can I use to cut the edge of the sleeper, so it doesn't come out further than the concrete wall? Its about an inch.
If I was using sleepers to replace the bricks in the photo, would I need a post at both ends of the sleepers? As there is a mess of concrete under there, on the fence end. Grass end is fine.
Or something completely different, could I possibly have some sort of waterfall or water feature to hide obvious change in bed height. Solar only!
