Serruria adscendens can be propagated from seeds or cuttings.

Propagate Serruria adscendens by semi-hardwood or heel cutting. In Harold Porter NBG, this species is propagated by tip cutting, taken from a firm shoot that has completed its growth period, from a healthy and disease free stock plant. Cut about 150 to 200 mm long shoots, removing the leaves on the lower third of the cutting. Dip the cuttings in a solution of rooting hormone for 5 seconds. Commercial rooting agents such as Seradix 2 or the liquid Dip and Grow can also be used. Place cuttings in a well-aerated mixture consisting of equal quantities of peat or milled bark and polystyrene. Rooting takes about 8 – 16 weeks. Rooted cuttings should be hardened off under 50% shade cloth for 4 weeks before being placed in full sunlight.

Sow seeds in late autumn in a well-drained, acidic soil consisting of two parts sand, one part of sifted bark and one part loam. Treat the seed with a smoke treatment; sow seed at the depth of one and half times the size of the seed, then cover the seeds with sand. Place them under 8 0 C night temperature and 20 0 C day temperature. Germination period varies from 1 – 3 months.
