Bituminaria bituminosa is highly drought-tolerant once established, requiring minimal watering. During its establishment phase, water regularly to encourage root development. Mature plants typically only need supplemental water during prolonged dry spells or extreme heat, thriving on natural rainfall in suitable climates. Avoid overwatering, as this can lead to root rot.

Pruning for Bituminaria bituminosa is typically minimal. Light trimming after flowering helps maintain a tidy shape and encourages bushier growth. Remove any dead, damaged, or leggy stems to improve air circulation and overall plant health. While hard pruning is generally unnecessary, the plant can tolerate it if rejuvenation or significant shaping is desired.

Bituminaria bituminosa can be propagated effectively by seeds or cuttings. Seeds benefit from scarification or soaking prior to planting to enhance germination rates; sow them in well-drained soil during spring. For cuttings, take semi-hardwood sections in late summer or early autumn, rooting them in a moist, sandy medium, optionally using rooting hormone for better success.

As an outdoor perennial, Bituminaria bituminosa is usually grown in the ground, making repotting unnecessary. If cultivated in a large container, repotting might be needed every few years to refresh the soil and provide adequate root space. Select a pot only slightly larger than the current one to prevent issues like overwatering and ensure healthy growth.
