Tritoniopsis triticea is difficult to grow because the corms tend to rot easily as they are adapted to the well-drained, nutrient-poor soils of the Cape (Graham Duncan pers. comm.) ; moles and porcupines eat the corms; nevertheless, the species is striking enough to encourage perseverance in trying to grow it. It is best planted in a well-drained, sunny rockery that gets little summer water, or on a slope in a water-wise fynbos garden. If these conditions cannot be met, this species could be tried in a deep container and staked when in flower.

Plant the corms in autumn, 3-4 cm deep with 6-8 cm spacing in well-drained soil. If planting in a container, use an acid, sandy growing medium such as three parts medium-grained river sand and one part fine acid compost or finely milled acid bark, and place them in a well-ventilated, sunny location. Give them a good soaking every seven to ten days during the growing period (autumn-winter-spring), and be careful not to over-water. When in flower, the stems can be staked to prevent them from falling over. This species requires protection when grown in very cold climates.

Propagation from seed: sow seed when it is ripe, in autumn-winter in a well-drained, sandy soil mix: 2 parts sand and 1 part milled bark. Cover them with a thin layer of fine-milled bark. Allow seedlings to stay undisturbed in the original container until the next season.
