Succulents (and cacti) are native to dry, arid climates, so they prefer sandy, well-draining soils.
In this manner, is it OK to plant succulents in regular potting soil?
They want a soil mix that will work for most anything. When succulents are small, they need more water, so a dense soil (like regular potting soil) works at that stage. … They will greatly appreciate the healthy new soil and room for their roots to spread.
In this way, what depth of soil do succulents need?
Some sources recommend preparing the soil three inches (8 cm.) deep, but others say at least six inches to eight inches (15-20 cm.) down is necessary. The deeper, the better when adding the outdoor succulent soil to your bed.
Can I use orchid soil for succulents?
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.
For the best potting soil for succulents, start with a basic cactus and succulent soil mix, or even an African violet mix, available at most garden centers. Then add some extra ingredients to find the one that will make watering easier, improve the drainage, and hold up a long time without compacting.
