Sow seed in autumn. Use a seed tray, place gravel or stones at the bottom to ensure sufficient drainage and fill it up with at least 10 cm of mixed soil suitable for succulent plants, such as 2 parts of coarse river sand / 1 part loam / 1 part sieved compost. The principal is that the soil should not become compact and have good drainage. Place the seed tray in a warm, sheltered area. During this time, the seed trays must be kept constantly moist, but must not be overwatered. It takes more or less fourteen days to germinate.

Repot the seedlings in the same soil mixture and add about a half part of vermiculite and some bone meal as fertilizer.

Othonna herrei must have a complete resting period during summer. This water-wise plant loses its leaves in early spring. It is an interesting plant to have in a rockery in the low-rainfall, winter-rainfall area, or in a pot where the watering can be controlled. Companion plants should also come from winter rainfall areas. It can be planted with small, non-deciduous, colourful succulents such as Crassula deltoidea, Aptosimum sp.  and deciduous ones such as Albuca spiralis, Cyanella lutea, and small species of Moraea.

Watering depends on the growing conditions: this information is to give an idea to guide the gardener. Use preferably rain water. It could be watered once every fourteen days in the growing season (winter time). Reduce the water gradually in spring so the plant can begin its resting period. Cease watering in summer. Start watering gradually in autumn.

It doesn’t need to be fed in cultivation, but it needs to be repotted every 5 years. No pests have been recorded except the attack by caterpillars on the leaves.
