Selecting the Right Soil
Succulents flourish in well-drained soil. That is why a drainage hole is so important. Likewise, using the wrong soil can kill a succulent. In fact, I have killed more succulents using ordinary potting soil than anything else. As I’ve said before, succulent roots don’t like to sit in water–they will rot.
The Perfect Succulent Soil Recipe
As a general rule, you want to plant succulents in a well-drained soil that has relatively large particles, about ¼” or 6mm. The best soil I’ve used for succulents combines equal parts pine bark fines, crushed granite and turface. Most of these ingredients can be found at Home Depot or Lowes, or at a local nursery.
If you’d like to purchase soil pre-mixed and ready-to-go, you can order your soil at Bonsai Jack. While I used to make the soil mix myself, I not get it exclusively from Bonsai Jack as it is great quality and convenient.
