Choosing the right substrate composition is quite important as it needs to be nutrient rich while still very high draining. Cacti like a wet / dry rotation so the substrate mix needs to be gritty to allow for drainage and for the roots to dry out quickly.
This substrate mix is the best that has worked for me personally. All ingredients are carefully and sustainably sourced.
The mix has 3 goals in common:
- Gritty and free draining
- Retains water without being “wet”
- Rich in minerals
There is nothing stopping you from buying the components individually and making your own substrate mix, I am just offering some pre made mixes for ease of use and not having to spend a fortune buying everything individually.
