Serruria dodii is one of the species recommended for use in fynbos gardens, especially water-wise gardens. Once the plants establish in the garden, they require very little watering. The species can be propagated by both seeds and cuttings. Seeds germinate well, but seedlings are often prone to fungal infection after being potted up. This susceptibility makes it challenging to grow and maintain the plants in the garden. The flower heads are bagged to collect seeds one month after flowering, allowing for pollination. The seeds will drop into the net bag and should be stored in suitable conditions at an appropriate temperature.

Seeds are sown from late summer to autumn (February to April) in the Western Cape, when temperatures begin to drop and nights are cooler. The seeds are treated with systemic fungicides before sowing to prevent pre- and post-emergence damping-off fungi and are exposed to smoke after sowing to break seed dormancy. The ideal medium is a well-aerated fynbos mix with a pH level between 5 and 7.

Cuttings are taken from summer to autumn. Semi-hardwood cuttings are collected early in the morning while it is still cool. They should be about 30–70 mm long, dipped in a semi-hardwood rooting hormone, and placed in a propagation medium. The trays should be kept in a mist house on warm benches at around 25°C until rooting begins. Seedlings and cuttings can then be transplanted into bags or pots to grow until they are ready for planting in the garden.

To prevent root disturbance, dryness, and weeds, apply a 5 mm layer of mulch in the garden bed. Chipped mulch is highly recommended, as it decomposes slowly and gradually releases small amounts of nutrients to the plants.
