It is possible to grow these plants by vegetative means as well as sexually. The quickest way of making more plants is by removing the small plantlets thatd evelop around the base of the dying mother plant, after flowering, or by taking leaf cuttings. These plantlets and cuttings can be rooted in coarse river sand: place them in trays filled with the coarse river sand in an area with good air movement and shade of about 40%.  Rooting normally occurs a few days after the cuttings are taken. The Plantlets and cuttings must be kept moist, especially after roots appear, until they are large enough to be planted out into the garden. 

Sow the seeds, which are light brown and very fine, on a fine sandy medium and water from below by placing the trays in a drip tray to allow water to be soaked up by the soil, and then remove the tray and let it drain.  The following medium usually works well with most succulents:

• 4 parts coarse river sand
• 4 parts fine river sand
• 1 part sieved well-rotted compost
• 1 part perlite
• 1 part vermiculite

Always treat seeds with a pre-emergence fungicide as seedlings often suffer from fungal diseases which causes them to die rapidly after germination. 

Remember that these plants are from well-drained, rocky areas and prefer a similar garden habitat with free-draining soil and plenty of direct sunlight in order to thrive.  

Other plants that do well with Kalanchoe luciae include Cotyledon orbiculata, Tylecodon paniculatus, Crassula rupestris, and Crassula arborescens.
