I used this without cement for a stone garden wall. However, I used a tamper to pack down the earth and then levelled it. I wouldn't recommend laying the stones down on mulch. They'll shift as the mulch deteriorates. It would be better to remove the mulch, tamp the earth and level, then gravel, then stones. I'm not a pro, but I did a lot of research.
