You don't have to do soil, I use only sand/fine gravel for my plants and it works great, but if you still want to you can do it either way, maybe mesh bags will make it less messy but as long as you cap it with a lot of sand it should be fine.
Some plants, called epiphytes, such as java fern and anubias, like to be glued to wood and rocks and not buried in the substrate, while some other plants, like stem plants, like to be buried.
