In this way, can you plant succulents in normal soil?
Regular potting soil isn’t the best choice for easy succulent cultivation, but with a couple of precautions you can make it work. Potting soil is mostly organic materials like bark, peat moss, and compost. It has a dense structure and it takes a while for it to dry.
Additionally, can you plant succulent aerial roots?
(Some plants, like mangroves, grown in very wet or swampy conditions actually use aerial roots for the reverse process — to help the plant to breathe. Succulents are likely to die from such wet conditions before aerial roots could be developed.) Aerial roots also provide support for plants in a few ways.
Can you plant succulents in just rocks?
Succulents have unique adaptations that have made them hardy and versatile enough to survive a variety of harsh conditions. Therefore, your succulent should be able to survive on or in rocks so long as they have just enough soil to cover their roots.
I would not recommend the orchid mix on any of your current succulents. Your plants will really hate getting too moist at root level, it will easily rot the fine roots or the base of your plant. I would rather add more pumice with the cactus mix.
