In this short video I'll show you how I laid out and built a rustic pumice stone wall. This wall was used to create a small garden of Dwarf Snake's Beard plants around a satellite dish on my porch roof.
The pumice stones are usually used in chimenae, a clay oven. If you live in a volcanic area you can find pumice washed up on the beach as it floats on water. I used pumice because it's lightweight, perfect to put on a roof.
