A better alternative is a succulent potting mix.

It is better to grow succulents in an indoor container during cold weather. 

First off, put some gravel at the bottom of a plant pot and fill it with a potting mix. 

The container for transferring Pacyphytum oviferum doesn’t have to be too deep. 

Next, plant the stems deeper into the pot and cover it with enough sand. 

Water the plant well enough for the soil to become moist, not wet. 

Place a thick layer of black pebbles over the soil for some visual appeal.  

Make sure to place the pot container in a sunny spot for the right dosage of sunlight.
