I am building a short retaining wall and have a question about back filling it as I did not dig the trench wide enough (and want to avoid more digging, honestly). This is in Minnesota so freezing is a concern. Also, I will be needing to add 6 inches of class 5 on top of it, so j just feel like putting that on top of pea gravel or key stone (recommended by the place that sold me the blocks) would be less stable than compacted soil plus class 5, but I am admittedly new to this. More information in the post below along with pictures. I appreciate any help. Thanks!
