Mixes of succulents benefit from organic matter, which increases the water content and absorbs nutrients. You can choose from decayed organic materials and mineral particles, which form loose soil, and with these characteristics, the plant will grow fine, because it is well aerated and does not hold water. The soil is not able to hold enough water, so water will not move as well. Also, roots cannot access nutrients. They will be more common in the northern regions, which are much cooler and less humid than those found in the eastern range.
