Serruria cyanoides is propagated from cuttings or from seed. Tip or heel cuttings are taken during spring or autumn. A rooting hormone is applied to the semi-hardwood cuttings that will stimulate rooting. The cuttings are rooted in a mixture of 50% milled pine bark and 50% polystyrene granules. Good rooting will only take place if the propagation house has misting and underbench heating. Rooting will take place from 5 weeks onwards. Once the cuttings have rooted, they are hardened off for 4 weeks before being planted. The rooted cuttings should be planted in a fynbos type soil medium. Fynbos type soils are usually nutrient poor and acidic. A suitable well-drained fynbos soil mixture consists of a mixture of acidic river sand, composted pine bark in equal parts and loam/topsoil.

Seed is collected from a mature flowerhead. The seed is sown in late summer or early autumn as the effects of higher day temperatures and cooler night temperatures play a vital role in initiating germination. The seeds can also be exposed to short periods of high temperatures followed by cooling water, which, by mimicking the autumn temperature regime, stimulates the seed to germinate very well. The seeds should be treated with a fungicide that prevents pre- and post-emergence damping off. Transplant the seedlings as soon as they are large enough to handle.

The young seedlings or potted cuttings should be grown in an area that is well ventilated and well lit. The plants should preferably be watered in the morning and may be fed with an organic seaweed-based fertilizer. The young plants can be planted out into the garden in autumn or during the cooler months. This allows the root system to become established before the onset of the hot, dry summer and gives the young plant a better chance to survive and thrive. Serruria cyanoides is best suited to sandy soil, and will grow well in fynbos or sandveld gardens. It is a small shrub, so plant it among other slightly taller plants, or in the front of a bed as an edging plant. Being a resprouter, it should not mind the occasional pruning to keep it neat and compact. Plant in full sunlight and ensure that the soil is well drained. Mulching with compost or woodchips during summer will keep the soil cool and help feed the plants.
