I bought a birdcage and several succulents with the intention of making something like this. I'm uncertain what to use as a planting medium. Obviously soil isn't the answer as it would flow right through the bars. Any ideas? Also, most of the plants I bought have babies. If I want to use those, do I need to let the stem form a scab before planting? I've also read that I need to use a rooting hormone. I'd appreciate hearing from anyone who has done something similar.
Thanks!!
