The klipdagga is fast growing and can be propagated by cuttings or seed. The seed develops and is held in the spiky sepals on the flower head and can be collected once they ripen and turn black and the sepals turn brown. Fill a seed tray with a mixture of composted bark and coarse river sand. Press the medium down evenly and firmly. Water the medium and allow it to drain. Once drained, the seed can be sown evenly on the damp soil surface and covered with a thin layer of the medium. Trays are to be kept in a warm semi-shaded area and watered daily until seeds start to germinate and the seedlings emerge. Once the seedlings are showing, reduce watering to 3 or 4 times a week.

Semi-hardwood stem cuttings can be taken in the late spring or summer months. Cuttings with internodes close to one another should be chosen and soft tips can be pinched out. Cutting material must be collected before 10 am to prevent the cuttings from suffering from heat stress. Material collected should be placed in a clear or light-coloured plastic packet with some water, to help keep the cuttings cool.

A propagation medium used for rooting should be well draining. A combination of sifted bark, coir and perlite at a 1:1:1 ratio can be used. Once cuttings are made with the lower leaves removed, they are to be dipped in a rooting hormone specifically for semi-hardwood cuttings. The cutting is inserted into the tray with the rooting medium, with no less than 3 nodes inserted into the soil. The trays with the cuttings are then placed under mist irrigation in the glasshouse, where the medium is kept moist, but not soaking wet and the leaves are kept damp in order to slow down transpiration from the leaf surface. After 3 to 4 weeks, cuttings will root. Once the cuttings have rooted, remove the cuttings from the misting unit and place them in the hardening-off unit where they will receive longer cycles of irrigation, but less frequently throughout the day. This helps to promote root growth and allows the rooted cutting to adjust to the new conditions, before being potted into a bag with potting soil.

When the rooted, hardened-off cuttings are ready to be potted, pot them into a well-drained potting medium. Newly potted plants are to be placed in a semi-shaded area for 2 weeks and then moved out into the full sun. When they are ready to plant out into the garden, they can be placed in a sunny area in the garden bed or in a rockery. L. ocymifolia is very easy to grow and is a very hardy plant. Plants can be planted in the rainy season, to allow them the chance to become established. In the warm months they can be watered up to 3 or 4 times a week.
