Your Delosperma echinatum requires rich, well-draining soil to thrive. We recommend using a cactus or succulent potting mix to ensure your plant has the best soil conditions. If you do not use well-draining soil or the container it is in does not have drainage holes, your plant will suffer from root rot. If you have regular potting soil, you can mix it with coarse sand to ensure your plant will have properly draining soil.
