When we bought our house 12 years ago, we started with this little raised bed made of rocks and soil (the one closest to you). We added two additional beds and the rock path a few years later.
These pallets will be sawed in half to outline our new garden beds. The rocks are nice, but need to be re-stacked as the soil shifts. I think it will look nice when it's all done. We are looking into soil delivery and trying to figure out what to plant. We cleared out some smaller trees and shrubs but still have to contend with limited sunlight.
