Today I ran into a couple want to be hardscapers. They were atempting to build a raised bed out of retaining wall blocks. The wall was prbably about a foot tall. The only problem was they had no base or footing under it. All they did was dig down a few inches to remove the sod, leveled the loose dirt and started laying the blocks. I say after a couple winters, the wall will settle, become un-even, look terrible and other wise be junk. I asked them about this and they just shrugged their shoulders and said "I hope that doesn't happen." Based on my limited hardscape expirience, this methood is incorect and will only lead to problems - your opinions.
