Water Bituminaria plumosa thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during the dormant winter months, allowing the soil to dry out more between waterings. Ensure good drainage to prevent waterlogging.

Prune Bituminaria plumosa to maintain shape and encourage bushier growth. Remove dead, damaged, or leggy stems in early spring before new growth begins.

Light trimming can be done throughout the growing season to control size. Pinch back young plants to promote branching.

Propagate Bituminaria plumosa from seeds sown in spring, or from semi-hardwood cuttings taken in summer. Seeds require stratification and light for germination.

Cuttings should be treated with rooting hormone and kept in a warm, humid environment until established.

Repot Bituminaria plumosa every 2-3 years, or when it becomes root-bound. Choose a pot one size larger than the current one with ample drainage holes. Use a well-draining potting mix, such as a cactus or succulent blend.

Repot in spring before the active growing season.
