I got a few frames for free and thought I would try using them for succulents…. here’s how I did it: First I sprayed the inside edge with sealer to help it repel water and hopefully last longer. I built a box to fit using a composite decking board (it’s made with plastic and won’t rot).
Sprayed one side of a piece of hardware cloth black (the dark color blends in better than shiny metal until the plants cover it up) and stapled inside.
Lined the hardware cloth with a layer of moss and filled with potting soil (packed tightly).
Stapled some shade cloth and plastic fence over the potting soil into the back and added wires for hanging (either vertical or horizontal). Inserted succulent cuttings by poking roots into the moss with a skewer or stick. Lie flat and water regularly until the cuttings are rooted well before hanging.
