What kind of soil environment is suitable for clivia? With soil recipe

Use humus soil; well-rotted peanut shells, pine needle soil, and tree bark can all be used, mixed evenly with coarse sand. Air permeability should be good, with stones placed at the bottom of the pot. It is best not to use garden soil. Clivia likes slightly acidic soil, so add a little ferrous sulfate when watering. I would not tell just anyone this.
