Podalyria buxifolia is easily grown from seeds. Collect seed pods when they are dark brown, dry and beginning to split open. Place in a paper packet and put in a warm, dry place such as a windowsill where the pods can explode. The packet will prevent the expelled seeds from being lost. Store seeds in a bottle and drop some insecticide dust into the it before closing the lid. This will prevent predators from eating all the seeds.

Sow seeds in late summer or autumn, although they will probably germinate at any time of the year. First soak the seeds in hot water of about 80 degrees Celsius until the water has cooled. Sow the seeds into a well-drained, acidic, potting mix in trays, plugs or individual pots, and cover lightly. Place containers in a well-ventilated, warm, sunny position where the seeds are protected from rain. Sowing directly into plugs or pots minimizes root disturbance and maximizes the number of surviving seedlings. Do not over-water and allow the medium to dry out a little between waterings. The seeds germinate very quickly within three weeks.

Podalyrias, like most legumes, are very susceptible to pre-emergence damping off and treating the seeds with a fungicide to combat this will improve the percentage of surviving seedlings. These fungicides are available at your local nursery. The seedlings should be potted into small pots at cotyledon stage before the first pair of true leaves develop. The potting mix should be well drained. A mixture of equal parts well-rotted pine bark or compost and coarse river sand is recommended. The small plants should be fed every week or second week with an organic liquid fertiliser. The seedlings will establish relatively quickly and should be ready to be planted into the garden in 12 months.

Podalyrias generally do not root easily from cuttings, and the plants are never as strong as seed-grown plants. Podalyria buxifolia appears not to root from tip or heel cuttings taken from the main branches. However, this species roots well if heel cuttings are taken from the underground rootstock, otherwise known as rootstock cuttings. Rootstock cuttings can only be taken from mature plants that have developed an underground rootstock from which new shoots emerge. This is only possible when the plant is resprouting after fire or after being cut to the ground. Cuttings can only be taken from wild plants if you are in possession of a collecting permit and have landowner permission.

Podalyria buxifolia is a lovely spreading, openly branched shrub. It is perhaps best planted mixed with other medium-sized fynbos plants. More time will be needed to experiment to see what manicuring is needed to bring out the best in this species. It is likely that a mature plant should be pruned hard to the ground every few years to encourage it to resprout; this should also encourage flowering. To achieve a more compact, bushy specimen, plant it in full sun and pinch back young growth.
