It’s a closeup, a detail even, from one of our own custom Succulent Wall Panels.
We make them! Right here in the Berkeley California workshop we call a Cactus Jungle.
How do we make them? Well we start with the finest of recycled wood boards and make a box! 4 sides and a back, with a wire mesh front. The material inside is green moss, i.e. sphagnum moss, with a backing of rock wool. That’s it! No soil, never no way.
So then you lay the completed box flat on a table and poke the moss with a pointy stick, or a pencil if you prefer, to generate a small hole that you can stick a succulent cutting into. Lots of succulent cuttings. Sedums, Crassulas and Sempervivums work well. An occasional Echeveria but not too many.
Make sure the cuttings are healed over by letting it dry for a few days before sticking it in the box. So this may be a multi-day process.
Then you let the box sit in a warm sunny location for 4-8 weeks until the cuttings have rooted into the boxes.
We also use greening pins to help hold the succulents in place, because we do have to transport the boxes to our greenhouse to root, and then back again, but you don’t need to use greening pins if you don’t want to. However, after the box is fully rooted and you want to hang it up on a wall, then you might want to check to see if any of the succulents have been less than fully rooted at that point at which time you may want to use some greening pins yourself to help keep the loose succulents from falling out.
