The plants perform equally well in boggy and well-drained conditions, but must be dried off completely during the summer dormant period, otherwise the corms tend to rot. The corms should be stored in dry soil in summer to prevent shrivelling. Wurmbea stricta is cold tender, requiring the protection of the cool greenhouse or conservatory in cold climates. The flowers are displayed to great advantage when interplanted with low-growing, late winter- and spring-flowering buchu species, such as Agathosma glabrata and Acmadenia heterophylla. The seed capsules of W.stricta develop rapidly and are attractive when ripe, displaying their dark brown, irregularly shaped seeds.

The plants are easily propagated by corm offsets that develop towards the end of the winter growing period. They can be separated from the adult corms at any time during the summer dormant stage by gentle tugging, and be replanted in autumn. Seeds are sown in mid-autumn, once night temperatures have cooled down significantly. The seedlings are most successfully raised in a well-drained medium such as equal parts of river sand and finely sifted compost, in deep seed trays or raised beds, placed in bright light or full sun, and watered every two to three days using a watering can with a fine rose cap. Seedlings should remain undisturbed for two years, and then be lifted and planted into containers or out into the garden in early autumn, at the beginning of their third growing season, during which they should flower for the first time.

Wurmbea stricta is not particularly susceptible to pests or diseases, but the petals are sometimes nibbled by snout weevils, and the corms may become infested with mealy bugs when grown in containers. Fungal rotting of the corms may occur if they are not dried off sufficiently over the summer months.
